Abstract:
The invention relates to mechanically cutting sewing materials, fibres and fabrics. The aim of said invention is to increase the elasticity, flexibility, reliability and the service life of a knife and to extend the technologically capacities of the device. The invention is characterised in that that the knife is made of thick metal and polymer strings combined into a multilayer structure, wherein the metal strip is placed between the polymer strips and is angularly abutted; the device is provided with a control unit for positioning the drive disc of the band knife whose cutting branches are arranged on the external surface of a post having a cross section which is embodied in the form of a two-side wedge and forms, at the end positions of the drive disc, equal acute angles &agr and β which range from 5 to 30 grads and whose bases are arranged on the same straight line and are opposite to each other; the device comprises a demountable unit containing the band knife, guiding and stretching supports which are embodied in such a way that they are removable, fixable in the removed position and can be brought close to the knife branches; a table for placing material is provided with a driven disc which is disposed above the material in a body which is connected to said table by a rod; the drive and the drive disc are disposed on the lower side of the table and an open lateral side is embodied around the cutting branches of the knife. In the second embodiment, said invention is characterised in that it comprises two-side band knives whose cutting branches are mounted on the external surface of the post whose cross section is embodied in the form of a two-side wedge and form simultaneously two equal acute angles &agr and β which range from 5 to 30 grads and whose bases are arranged on the same straight line and are opposite to each other.
