Splicing Press Machine

Timing Belt Splicing Machine

A timing belt splicing machine is a specialized industrial equipment used to join the ends of timing belts (such as polyurethane timing belts, rubber timing belts, HTD timing belts, and GT2 belts). It utilizes advanced methods like hot melting or mechanical fastening to create seamless, high-strength joints that ensure smooth power transmission and prevent belt slippage or breakage.

Hot-Melt Splicing Machine for PU Timing Belts

Belt width 100 / 150 / 200 mm (custom) · Up to 230 °C · Pneumatic pressure · Water-cooled platen

▎Introduction

1 Timing belt joint machine.jpg

BAYRICH Timing Belt Splicing Press is a dedicated hot-press machine for making endless splices in open-end PU (polyurethane) timing belts. The upper and lower platens melt both belt ends, which are then pressed together under even pressure and cooled to form a seamless endless belt. Compared with mechanical fasteners and cold bonding, a hot-pressed splice gives higher strength, smoother running and longer service life — the preferred joining method for PU timing belts. Built-in water-circulation channels and temperature sensors in the platens ensure stable temperature control; pneumatic pressure with interchangeable molds covers belt widths of 25–200 mm and a wide range of tooth profiles, including double-sided timing belts.

▎Key Features

● Seamless endless belt—splice approaches base-belt strength; no tooth jumping	● Precise temperature—built-in sensor + water cooling for consistent quality
● Even pressure—pneumatic pressure gives uniform splice thickness, no voids	● One machine, many sizes—change the mold for different widths and profiles
● Double-sided belts—double-sided timing belts can also be spliced	● Lower stock—keep open-end roll stock and splice any perimeter on demand

▎Applications

● Food & packaging—filling, labeling and pouch-packing lines	● Printing & textile—presses, dyeing and setting equipment
● Tobacco & logistics—cut-tobacco lines and sorting conveyors	● Electronics assembly—3C, lithium battery and automated lines
● Automotive—final assembly and servo drive systems	● Custom retrofits—on-site endless belts of any perimeter

▎Operating Procedure

1. Cut both belt ends square, with the teeth aligned;	2. Install the matching mold and position both ends in the upper / lower molds;
3. Set heating temperature and time; bring the platen to process temperature;	4. Move the platen between the molds and lower the upper platen so both ends melt against it;
5. Retract the platen and press the upper platen down to weld;	6. Hold pressure, cool and set, then open the mold and trim the seam.
