The article provides information on the introduction of automatic cutting processes for a continuous plastic bar of soap with a new and improved
design. When obtaining a piece product from a continuous plastic beam, problems arise with the implementation of the cutting process with continuous movement of the beam and ensuring the size of the cut piece. In this case, it is necessary to ensure the synchronous movement of the plastic beam with the cutting body or to discretize these processes. As a result of the conducted research, a fundamentally new design was developed that provides a high level of cutting dimensions and accuracy, perpendicular to the cutting surface, taking into account a number of
disadvantages of the above cutting methods. The results of experimental tests of the new design ensured the accuracy of the cutting-edge dimensions and the perpendicularity of the cutting surface in comparison with existing devices.
