DEVICE FOR STEPPED RUBBER CUTTING AND METHOD FOR STEPPED RUBBER CUTTING USING SAID DEVICE Russian patent published in 2017 - IPC B26D1/00 B29B17/00 

FIELD: physics.

SUBSTANCE: device is designed for implementing a method for stepped rubber cutting and includes a frame on which is mounted a device for fixing material (3) to be cut, configured to move rubber (2) in a different direction, a hydraulic cylinder (6) with a rod (6), arranged so that the rod is directed towards the rubber fixing device, a blade (1) mounted on the rod of the hydraulic cylinder; and means of controlling the hydraulic cylinder and the rubber fixing device. The device is provided with a support having an opening, the width of which is greater than or equal to the width of the blade, for passage through said opening, wherein the blade is in form of a hook whose cutting surface is located on the outer side, to provide cutting when the rod is pulled towards the hydraulic cylinder. The method is realised as follows: the material to be cut is fixed on the fixing device and the material is then moved so that it is between the cutting part of the blade and the support, the blade is pulled towards the hydraulic cylinder through said opening of the support. Part of the material which falls on the cutting surface of the blade is cut, the blade is then moved beyond the opening for cutting, and the material is moved by the fixing device so that the cut part is worn on the blade. The blade is then re-pulled towards the hydraulic cylinder through said opening of the support and cutting is continued.

EFFECT: device enables to cut rubber in the form of large-size tyres into segments on small-size equipment with low energy costs.
