Machine for producing fold grooves in corrugated paper

摘要

The corrugated paper(42) passes through a channel(S) between two pairs of endless members(10,12). The components(26,28) for making fold grooves are attached correspondingly on each of the endless members. The members are toothed belts or chains and pass over pulleys or chain wheels respectively. The components for forming the grooves consist of segments(26,28), the respective cross sections of which form protrusions and cavities.
