4 - Vulcanizer in place heating up

(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.
