Research on Redesign and Manufacturing of an Automatic Roll Cutting Machine

Abstract

Textile-and-garment industry is one of the largest economic sectors in Vietnam, with 4000 enterprises and a turnover of 20 billion USD/year. Therefore, designing and manufacturing are essential tasks for roll fabric cutting machines to serve the textile and garment industry. First of all, theoretical calculations are formulated for an automatic roll cutting machine. Then, simulations are conducted by a combination of MITcalc and Catia software. A prototype of a fabric cutting machine is manufactured and experiments are implemented. The experimental results show that the machine stably works and overcomes the disadvantages of the popular cutting machines with the core-free roll on the market. The results also found that the size tolerance is achieved about ± 0.5 mm, and this ensures good working quality. The designed machine has a significant contribution to the textile and garment area in decreasing the cost of the cutting process.
