Rectifying longitudinal cutting system for automatic cloth cutting machine

The invention provides a rectifying longitudinal cutting system for an automatic cloth cutting machine and relates to the field of textile equipment. Rectifying longitudinal cutting devices are located on the two sides of a cloth and each comprises an edge-following rectifying device, an edge-following control adjusting system and a longitudinal cutter assembly. The edge-following rectifying devices unfold the rolled edge of the cloth and detect the position of the cloth edge, the edge-following control adjusting systems adjust movement of the edge-following rectifying devices to make the cloth edge meet the precision requirement of detection of the edge-following rectifying devices. The longitudinal cutter assemblies longitudinally cut the edge of the cloth according to the required width. According to the rectifying longitudinal cutting system, the edge-rolled cloth can be longitudinally cut, the efficiency is high, the cutting-off precision is higher, and the labor cost is greatly saved; the edge of the ed
