  • Arrangement for cutting thin-walled belts from a closed band of rubber
    Patent number: 5188010
    Abstract: An arrangement for cutting thin-walled reinforced closed bands of rubber into rectangular belts having the same width is suggested wherein the closed band is tensioned between two rollers. By deflecting one of the two rollers, the closed band experiences a force component parallel to the roller fixed in position which drives the closed band against a stop. With this arrangement of the stop on the end facing toward the cutting device even thin-walled closed bands can be cut into rectangular belts with a uniformity in width not attained previously.
