SCHWABE USA - Cutting Belt Installation
​
SCHWABE Press Option now includes a Belt Vulcanizing Channel for reduced downtime and Quicker Belt Changeover of both Urethane and Nylon cutting belts.
  • Belt installations on SCHWABE cutting press systems is now even easier to install with the SCHWABE unique vulcanizing channel, incorporated into the feed system of the press.​
  • Utilizing the new SCHWABE vulcanizing channel installing a cutting belt is up to 15% faster than conventional methods. 
  • Note: Belt vulcanizing can be used with a urethane or nylon cutting belt.
The vulcanized finger splice shown below is a process recommended for applications where 100% operating tension is required or where a smooth splice surface area is required.
(i) SCHWABE USA vulcanizing channel is located beneath the removable belt support plates of the feed system.

(iii) The cutting Belt Ends are squared to ensure a straight spice and correct belt tracking.
- The new belt is fed through into position of the SCHWABE vulcanizer press channel
  • Feeding new belt across bottom base weldment and around the belt pulley of SCHWABE press towards the vulcanizer press channel
 (iv) The bottom section of the vulcanizer is positioned in the SCHWABE vulcanizer press channel and the belt with single splice is placed on the bottom platen
 (iv) The bottom section of the vulcanizer is positioned in the SCHWABE vulcanizer press channel and the belt with single splice is placed on the bottom platen
(v)The finger sliced belt is placed square on the vulcanizer press using SCHWABE purpose built channel, and the seams are aligned before clamping and the top platen is secured..

  • The new belt is clamped, with top section of belt vulcanizer, the heat platen is now in position.  
  • The squareness of the belt ends is double checked using a square before clamping.

(vi) Once the belt vulcanizer heat platen is in position, the belt will be heated to 340F.
In order to attain the recommended belt temperature levels, the temperature of the platens may have to be increased approximately ten degrees higher.

After the cure time has passed, the temperature is cooled with cool water until the temperature falls below 100 degree F.

Summary
  • SCHWABE USA presses using die cutting on a urethane or nylon belt can be equipped with an innovative vulcanizer press channel.
  • The SCHWABE USA vulcanizer press channel makes it easier to work  the belt into position on the heat platens of the vulcanizer press and to align the finger splice.
  • The SCHWABE USA vulcanizing channel saves up to 15% on the conventional endless belt installation time.
