Analysis of the Device for Unwinding the Tape Material

Abstract

Ensuring constant tape tension and the absence of sagging in machines and equipment using rolled materials determines the quality of the resulting products. Based on an analysis of the known solutions, a new mechanism for unwinding and pulling rolled material is proposed. Static and dynamic analysis showed that the developed device provides a constant tension force for the wound tape of material and does not allow sagging and inertial runout of the roll. In addition, the created mechanism makes it possible to reduce jumps significantly in the tension force of the tape during acceleration and deceleration of the broaching drive.
