PCT No. PCT/DE88/00159 Sec. 371 Date Nov. 16, 1988 Sec. 102(e) Date Nov. 16, 1988 PCT Filed Mar. 16, 1988 PCT Pub. No. WO88/06959 PCT Pub. Date Sep. 22, 1988.The invention relates to a strand cutter, more particularly for granulating plastic materials. It has for its object the provision of a strand cutter in which the fixed bed knife can be replaced with a new bed knife without interrupting the granulating process. This is to prevent the deterioration of the cutting quality, and thereby the shape of the granules, due to the progressive wear of the bed knife or to prevent down-times during the changing of the knife. This object is achieved according to the invention by keeping the bed knife (2) in a guide free from play at right angles to the delivery direction of the strands (3) and moving the bed knife (2) forward at a low feed rate or replacing it with a new bed knife (2') during the granulating process.
