Product catalog summary
Introduction: The document provides instructions for joining or repairing Flat-Flex belts using joining tubes. It outlines the necessary tools, procedures, and precautions to ensure a successful and safe belt joining process.
Selection of Tube Length: The joining tube should be slightly less than two-thirds of the belt space. If the exact length is unavailable, choose the nearest shorter tube.
Required Tools: Safety glasses, needle nose or flat end pliers, wire straightening tool (optional), and side-cutting pliers are needed. The wire straightener and pliers can be ordered from the sales department.
Cutting the Space Wire: The first cut should be made at one-third of the space length in non-driven, odd-numbered spaces. Ensure the joining tube can cover the longer wire section.
Procedure:
  • Relax the belt tension adjuster and unzip a single strand from the belt's upper end.
  • Make the first cut and weave the short piece through the lower and upper belt spaces, turning clockwise to join the ends.
  • Use pliers to loop the edges together and straighten the wire.
  • Repeat the process for subsequent spaces, turning anti-clockwise as needed.
  • Insert the joining tube over the wire sections, ensuring a minimum 5 mm gap from the Z-form.
  • Use bolt cutters to secure the joining tube, avoiding the cut wire position.
Final Steps: Repeat the joining process across the belt width. For added security, crimp the tube twice on each side of the cut wire. For wider belts, use cable ties to hold the ends together temporarily.
Additional Information: Tube joins are available for all belt wire diameters from the Wire Belt Company. Contact customer services for assistance.

Flat-Flex® Tube Join Instructions Make Flat-Flex endless – with joining-tubes Application – To join a new belt or to repair a damaged belt. Please note: Before undertaking any other method of belt joining, including the tube method described here, it is important that a risk assessment is undertaken and that all applicable regulations are complied with. Selection of Tube Length The tube length should be a few millimeters less than 2/3rds of the belt space. If this joining tube length is not available then choose the nearest shorter available tube. Which tools do you need? • Safety Glasses • Needle Nose and /or Flat End pliers • Wire Straightening tool (optional). • Side-cutting pliers – Knippex Compact Bolt Cutters are ideal for both cutting of wire and crimping the tubes. You can order the wire straightener and pliers from our sales department. Where should the space wire be cut? The first cut is made at one third of the length of the space, exclusively in those spaces that are not driven – the odd numbered spaces. CAREFUL: The cut must ALWAYS be set so that the joining-tube can be pulled completely over the longer part of the cut wire section. These spaces are cut through and later put together again with the joining-tubes. To avoid confusion later, only cut off the part you need to use next. Space length The joining-tube must fit completely over 2/3
