The textile industry (distribution and spreading roll): general form of screw expanding plate, screw thread spreading roll, bending roll expander, a telescopic plate expander, cone roller expander etc.. Shearing machine common thread spreading roll (a passive or active, positive or negative, expand expansion) car and wound. Because the surface of the roller body and the fabric surface sliding, threaded on friction fabric produced zonal component. Factors affecting the efficiency of expanding: the fabric warp tension; surface relative linear velocity; wrap angle size; woven material properties; screw thread section shape, spiral angle size (usually 15.) , lead (usually 24~48mm) etc..
