Step 1

Measure the overall width of the belt in inches from outside edge to outside edge.

Step 2

Count the number of wire strands in a 12 inch length of belt. This will determine the exact pitch (or distance from each woven strand of wire to the next) in terms of wire strands per foot.

Step 3

Measure the wire diameter with calipers or a wire gauge

Step 4

Check to see if the belt has single loop edges, C-Cure Edge®, or double loop edges. Measure the loop edge width.

Step 5

Count the number of rectangular openings (spaces) across the width of the belt.

Step 6

Determine if all the spaces are of equal width. Occasionally, end spaces will be of different width than the middle spaces.

Step 7

Determine belt material. Most common materials are stainless steel and music wire. Music wire has a strong magnetic attraction. Stainless steel has only a slight magnetic attraction. Use a magnet to distinguish.

Flat-Flex® single loop edge (SLE) using full strand joining method

Tools you will need:
  • Safety glasses
  • Flat end pliers
  • Needle nose pliers
  • Cable ties/soft wire/string (optional)
  • Cutting pliers
  • Wire straightener (optional)
  • Necessary tools for conveyor belt take up adjuster

 
Step 1 – Before you begin joining

  • Slacken any belt take up adjuster to allow the maximum take up capability when belt is fitted.
  • If possible move the two ends of the belt to be joined to the discharge end of the conveyor unit. This may help to hold the belt in position while joining.
  • Confirm that the edge loops are curving back away from the direction of belt travel (as shown in Diagram 1). If not, check to be sure the belt is not threaded backwards on the conveyor.
  • Remove a strand (joining strand) from one end of the belt, or spare belt roll. Lay the strand down between the two belt edges and check to see that the edge loops are going in the same direction as the belt’s edge loops. (The strand must also be “right side up” for it to lay flat. You will know immediately if you have installed the joining strand “wrong side up” and will have to start over.)
  • If necessary you may want to attach the two ends of the belt together, to maintain stability, using cable ties, soft wire or string in the outside spaces (see note 3 below).


Step 2 – Begin Joining In The Center

  • FLEX the strand from each side enough to INSERT the ends into the two spaces next to the center space (Spaces A and B - Diagram 1).
  • INSERT the strand ends up through the center space of the opposite near side edge (Space C - Diagram 2).
  • Pull the ends of the strand through until the center space “locks” in place.
  • Use pliers or the Wire Belt wire straightening tool to STRAIGHTEN the wire in the center space (Once the center is connected, you may remove the ties holding the belt edges together).


Step 3 – Weave Strand To One Side

  • FLEX or BEND in the center of the next space and INSERT it down through and around the Z-bend in this space on the belt end wire closest to you (Space D on Diagram 3).
    Note: Always try to avoid bending the wire at the Z-bend!
  • BEND the wire toward the center and INSERT up through and around the Z-bend next to the center space (Space E on Diagram 4).
  • Pull the strand wire through the mesh and STRAIGHTEN it with your pliers or wire straightener.
    TIP: Pull the strand in the direction that it goes through the Z-bend links.
  • Repeat these three moves until you reach the side edge of the belt (Diagram 5).

  • Using your pliers, connect the join strand’s edge loop to the belt’s edge loop on the near edge by hooking the edge loop up through Space F on Diagram 5.
  • Connect the edge loop on the far edge of the main belt to the strand’s edge loop by gently flexing the outer space strand up through the connected join strand using your flat nose or needle nose pliers (Diagram 6).
  • STRAIGHTEN the strand with your pliers.

Step 4 – Weave Strand To The Other Side

  • Repeat number 3 on page 6, going in the opposite direction, weaving to the other side edge of the belt (Diagrams 3 through 6).
  • If you are installing a new belt, you are finished joining. *See Important notes below.

Step 5 – Check Drive Shaft Sprocket Alignment

  • There should be a typical 3/16” clearance between all sprockets (and/or blanks) and the Z-bends next to them.
  • Check alignment of sprocket teeth with a straight edge (only necessary if the sprockets are not keyed to the Drive Shaft).
  • Drive shaft set up should be according to the Standard Arrangement.

Step 6 – Check Drive Shaft Sprocket Alignment

  • Z-bends should NOT come in contact with ANY conveyor component (including end rolls, wear strips, transfer support rails or nose bars, etc.).
  • Adjust as needed.

Step 7 – Check Drive Shaft Sprocket Alignment

  • Flat-Flex® is a low tension belt. Use minimal tension… only enough so that drive sprockets properly engage the belt.
  • Run conveyor and check to be sure it runs smoothly.
    NOTE: Too much tension will cause premature belt failure!

* IMPORTANT NOTES:

  • Avoid permanent deformation of the ‘Z’ form links when joining. To assist it may be necessary to place a bend in the wire space adjacent to the space being woven; however you must ensure that this wire bend is straightened before continuing the joining operation. Re-straightening of wires at this stage or at the end of joining can be achieved using the flat end or needle nose pliers or wire straightener.
  • Avoid any bending of the join strand wire in their vertical plane. Any necessary bending of the wire strand should take place in the horizontal plane.
  • For wider belts it may be necessary to secure the 2 ends together at more regular intervals across the belt which can be removed as the strand is woven towards the outside edge.

Flat-Flex® double loop edge (DLE) using full strand joining method

Tools you will need:
  • Safety glasses
  • Flat end pliers
  • Needle nose pliers
  • Cable ties/soft wire/string (optional)
  • Cutting pliers
  • Wire straightener (optional)
  • Necessary tools for conveyor belt take up adjuster

CLICK HERE FOR SLE JOINING INSTRUCTIONS.


1. DIAGRAM A

Flat Flex double loop edges diagram 1

  • At the last space before the double loop edge, gently bend the joining strand in the center of the last space.
  • Insert the end of the joining strand into the double loop edge (small space) on the near side. You will need to rotate the wire to feed the DLE through the space.
    NOTE: If you have difficulty with this process you may unhook the main belt near edge loop first and then re-connect this at the final stage of the process.


2. DIAGRAM B

Flat Flex double loop edges diagram 2

  • Insert needle nose pliers from underneath, grab the center of DLE on strand and pull up into space.
  • Straighten initial bend


3. DIAGRAM C

Flat Flex double loop edges diagram 3

  • Flex the belt by pushing down in center of last row of spaces on the near edge.
  • Rotate joining strand so you can push the end up from underneath the last space on far edge.
  • Hook DLE up over last large space Z-bend.
  • Straighten any distortion to this connected Z-bend using needle nose pliers or the wire straightening tool.


4. DIAGRAM D

Flat Flex double loop edges diagram 4

  • Connect the splice strand edge hook to the near side loop edge using pliers hooking up under the near edge strand.


5. DIAGRAM E

Flat Flex double loop edges diagram 5

  • Connect the far side loop edge by hooking it into the splice strand using pliers.
  • Connect the opposite edge of the belt in the same manner, only in mirror image.
  • Straighten any bends in wire strands.

IMPORTANT NOTES:

  • Avoid permanent deformation of the ‘Z’ form links when joining. To assist it may be necessary to place a bend in the wire space adjacent to the space being woven; however you must ensure that this wire bend is straightened before continuing the joining operation. Re-straightening of wires at this stage or at the end of joining can be achieved using the flat end or needle nose pliers or wire straightener.
  • Avoid any bending of the join strand wire in the vertical plane. Any necessary bending of the wire strand should take place in the horizontal plane.

 

How to make joining clips

To make your own belt joining clips you will need the following tools: 2 sets of pliers and 1 pair of wire cutters.

Next follow steps 1-5 below to make the following types of belt joining clips:

  • One-space clips
  • Three-space clips
  • Double loop ends clips






 

Flat-Flex® single loop edge installing joining clip method

Tools you will need:
  • Safety glasses
  • Flat end pliers
  • Needle nose pliers
  • Cable ties/soft wire/string (optional)
  • Wire straightener (optional)
  • Necessary tools for conveyor belt take up adjuster

Joining clips come in two varieties: single space and 3-space clips. The 3-space clip is obviously stronger because its center space is woven into the belt as in the full strand joining method. These two types of clips should be used together, whenever possible to create a stronger joint and to help minimize the spacing gaps in the belt. (For example, a 7-space belt could be joined using two 3-space clips... whereas, a 9-space belt would use 1 single and two 3-space clips. See "HOW MANY CLIPS" below.)

IMPORTANT NOTE:

  • Two different end loops from adjacent clips cannot be attached to the same Z-bend. Only one joining clip end loop per Z-bend is allowed.
  • If a belt has damage in more than one place on account of fatigue, do not try to repair it. Install a new belt. Also, never save old belts to use for repairs because they have already been weakened from use. Purchase several extra feet of new belt to use exclusively for repairs.
  • The use of clips produces a double space pitch gap between adjacent clips and you should fully assess their use for both the product process and safe use in the operating environment.


 


 

 

1. Before you begin joining

  • Turn off and lockout power to the conveyor.
  • Slacken any belt take up adjuster to allow the maximum take up capability when the belt is fitted.
  • If possible move the two ends of the belt to be joined to the discharge end of the conveyor unit. This may help to hold the belt in position while joining.
  • If necessary you may want to attached the two ends of the belt together to maintain stability, using cable ties, soft wire or string in the outside spaces. For wider belts it may be necessary to secure the 2 ends together at more regular intervals across the belt, which can be removed as the clips are woven in.
  • Plan out the number, type and placement of joining clips by laying them out in position across the belt.
  • Make certain that no two edge loops on the clip hook around the same Z-bend and that all closed loop edges point in the direction of belt travel.

2. Begin installation with the center space:

  • Begin installation with the Center space
  • If installing a single clip, install the clip around the center space on the far end of the belt.
  • Using needle nose pliers grip the joining clip, and in turn hook the two single loop edges up through and into the center space on the opposite belt end.
  • -OR- If a 3-space clip is used:
  • Gently bend the clip in the center and insert the clip ends down into the spaces either side of the center space.
  • Then insert the clip ends up through and into the center space of the opposite belt end and pull through until the center “locks” into place.
  • Then, gently straightening the wire, hook the single loop edge down through and around the space adjacent to the center space.
  • Use the needle nose pliers to grip the single loop edge, hook it up through and into the space adjacent to the center space on the opposite end of the belt. Repeat for other edge loop.
  • Straighten the wire with pliers or the wire straightener tool.

3. Install the next joining clip on an outside edge if a single clip is used:

  • Remove the tie holding the ends together.
  • Insert the joining clip around and through the far end edge space of the belt.
  • Connect the splice clip edge loop to the near side belt edge by gently flexing the splice clip edge loop up and through the near side outside space. The use of needle nose or flat end pliers may help in this process.
  • Grip the joining clip with yoiur pliers and hook the second edge loop up through and around the adjacent Z-bend on the near end of the belt.
  • -OR- if a 3-space clip is used:
  • Remove the ties holding the edges together.
  • Bend and insert the joining clip around the second space in from the belt edge and insert the clip ends up through the second space into the opposite end of the belt. Pull through until center locks in place.
  • Using needle nose pliers connect the joining clip edge loop to the near side belt edge by gently flexing the joining clip edge loop up and through the near side outside space. Then hook the far outside edge loop up through the edge of the joining clip.
  • Then on the other end of the splice clip hook it down through space number three on the far belt edge, then flex the edge loop down and up through second space on the near end of the belt.
  • Straighten wire with pliers or Wire Belt’s Wire Straightening tool.

4. Install joining clip on the opposite edge:

  • Install the same type of joining clip on the opposite edge in the same way

5. Install the remaining joining clips:

  • Install the remaining joining clips, as appropriate, across the belt. There should be the exact same number and type of joining clips on either side of the center clip (the first clip you installed)

6. Re-tighten the conveyor belt tension

EZ-Splice® belt joining instructions

Tools you will need:
  • Safety glasses
  • EZ-Splice Strand
  • Profiling Pliers

 

EZSplice 1

  • Place the EZ-Splice® strand between the two ends of the belt to be joined, match and align the spaces of the strand with the spaces of the belt.

 

EZSplice 2

  • Make sure that the cut end of the EZ-Splice® strand is on the bottom.
 

EZSplice 3

  • Once both ends of the belt are aligned with the spaces in the EZ-Splice® strand, turn the EZ-Splice® strand over and hook both end loops in as shown below.

 

EZSplice 4

  • Hook end loop in place.

 

EZSplice 5

  • Repeat opposite end.

 

EZSplice 6

  • EZ-Splice with endloops hooked.
 

  • Now that you have both end loops hooked, turn the EZ-Splice® strand 180º or 1/2 turn.

 

  • Turn and insert the second space of the EZ-Splice® strand through the second space of the belt to be spliced and repeat every other space until the end of the belt is reached.

 

  • Now the bottom half of the joint is completed.
 

  • Once the bottom half is all locked into the appropriate spaces across the width of the belt, turn the EZ-Splice® strand about 1/4 of a turn or about 90º up as shown.

 

  • Take the top half of belt and hook the first space over and through the first space of the EZ-Splice®.

 

  • Then repeat every other space until the end of the belt is reached.

 

EZSplice 13
  • Now that joint is in place, follow step 5 and step 6 to lock your EZ-Splice® in place.
 

EZSplice 14

  • Insert the beveled edge of the bit into the jaw slot, pushing in with your index finger until you hear a click indicating that the bit is locked into place. Make sure to use the correct bit that matches your belt.
 

EZSplice 15

  • Starting in the center of the belt to be crimped, insert the low jaw of the profiling pliers into the joining strand, match the joint bend of the strand up with the corresponding grove on the lower jaw of the profiling pliers and crimp down.
  • Moving outward, insert the lower jaw into the next joint bend making sure to match it up again with the corresponding grove on the lower jaw. Repeat until the end of the belt is reached.
  • Crimp the Z bends in the splice strand to the proper profile height to insure required belt clearance throughout the conveyor circuit. Profile pliers will bottom out when fully crimped.

Sprocket Placement

Flat-Flex® typically uses pairs of drive sprockets located in the odd-numbered spaces, with blanks supporting the outside edges of the belt. This arrangement facilitates sprocket alignment and allows the use of splicing clips for installation and belt repair.

The correct clearance must be present between every sprocket and its adjacent Z-bend. This cannot be emphasized too often. Belt life will be severely reduced if the Z-bends come in contact with any component of the conveyor.

General Best Practice: Wire Belt recommends that only genuine Wire Belt sprockets and blanks be used. Commercially available sprockets can cause the belt to surge, jump teeth, and may cause premature failure.
