CS263487B1 - Device for magnetic tape's tensioning stabilization - Google Patents

Abstract

The device belongs to the magnetic field record. The goal is to ensure optimal security tape winding and tensioning speed in its rewind mode. Established oile is achieved by putting the device on stabilizing the tension of the magnetic tape are rotational side rotation speed sensors are introduced parts, electrically connected together with electric motors and a system of stabilization of speed rotation of the electric motor coupled to the regulated portion resistance
