Daroitex's new modular fabric inspection machine for woven and knit fabrics accommodates batched or folded packages. Its modular design permits quick reconfiguration to accommodate varying fabric and package types. Inverter controlled motors permit separate, automatic adjustment of loading and unloading speeds. An electronic racker automatically monitors fabric tension without stretching the fabric. A photocell controls a novel automatic centering device. Batching includes automatic analysis of roll density.
