Step 1 – Begin Splicing In The Center

• Move the two ends of the belt to be spliced to the
  discharge end of the conveyor unit.
• Confirm that the edge loops are curving back away
  from the direction of belt travel (as shown in Diagram A). If not, check to be sure that the belt is not threaded backwards on the conveyor.
• 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 splice strand “wrong side up” and will have to start over.)
• BEND the strand from each side enough to INSERT the ends into the two spaces next to the center space (Spaces B and D in Diagram A)
• INSERT the strand ends into the center space of the
  opposite edge (Space 3 in Diagram B)
• Pull the ends of the strand through until the center space “locks” in place (You should be pulling the strands toward you)
• 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 2 – Weave Strand To One Side

• BEND one end of the wire up and INSERT it around
  the Z-bend in the next space on the edge of the wire
  closest to you (Space 5 on Diagram C). Always try to avoid bending the wire at the Z-bend!
• BEND the wire toward the center and INSERT around the Z-bend next to the center space (Space D on Diagram D)
• Pull the strand wire through the mesh and STRAIGHTEN it with your pliers
• Repeat these three moves until you reach the side edge of the belt
• Using your pliers, connect the strand’s edge loop to the belt’s edge loop (on the far edge)
• Connect the edge loop on the near edge of the belt to the strand’s edge loop
• STRAIGHTEN the strand with your pliers

Step 3 – Weave Strand To The Other Side

• Repeat the steps in #3, going in the opposite direction, weaving to the other side edge of the belt (Diagrams C through G)
• If you are installing a new belt, you are finished splicing

Step 4 – Check Drive Shaft Sprocket Alignment

• There should be a 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)

STEP 5 – Check Entire Belt Circuit

• 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 6 – Adjust Tension

• 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!

Splicing a Flat-Flex® Double Loop Edge

DIAGRAM A

• At the last space before the Double Loop Edge, gently bend the splicing strand in the center of the last space.
• Insert the end of the splicing 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.

DIAGRAM B

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

DIAGRAM C

• Flex the belt by pushing down in center of last row of spaces
• Rotate splicing strand so you can push the end up from underneath the last space on far edge.
• Hook DLE over last large space Z-bend.

DIAGRAM D

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

DIAGRAM E

• 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.
