Problems solved by technology

[0005] Chip shredders can generally only be used with sheet plastic material that is sufficiently solidified by cooling, at least in its surface area, because in the case of the traditional design of the device briefly described above, it would easily result in a still insufficiently solidified agglomeration of plastic materials

Abstract

The invention relates to a comminution device for the production of particles (16) from a strip-shaped material (17), said device comprising a longitudinal cutting device (1) having a first cutting roller (2) and having a second cutting roller (3), and a transverse cutting device (4), which is disposed downstream from the longitudinal cutting device (1), wherein the first cutting roller (2) and the second cutting roller (3) each have special profiles according to the invention.

Description

technical field [0001] The invention relates to a shredder for the production of pellets from sheet material as claimed in claim 1 or the preamble of claim 2 . Background technique [0002] Such shredders for producing granules (more specifically, granules in the form of regular-shaped flakes) from sheets usually have a longitudinal cutting device with cutting rollers and a transverse cutting device with cutting rollers, wherein the transverse cutting device is positioned at the longitudinal cutting behind the device. The supplied sheet is first shredded by such a shredder into a plurality of longitudinal strips, and then the longitudinal strips are shredded transversely to the direction of travel of the sheet by a cross-cutting device, which results in the generation of corresponding granules. This could serve as an alternative to crushing the material, which would, in contrast, result in a less regularly shaped flake morphology. [0003] Such shredders are used in partic...
