摘要

An apparatus for curling yarn, comprising a filling curling device with a chamber that confines the yarn core and which defines curling, heating and cooling zones arranged successively along said chamber, and yarn feeding rollers mounted at the entrance of said chamber in order to transport the yarn to the curling area to form a core of curled yarn with said chamber, characterized by a cylindrical means mounted so as to rotate parallel to the axes of said feeding rollers and arranged in the unión of said curling and heating zones in order to independently control the control of the pressure on the core in said heating and cooling zones of said chamber, said roller being provided with a surface that grabs the core and which projects in said chamber in said joint, as well as a means for positively and rotatively actuating said cylindrical means independently of the pressure exerted thereon by the core within said crimping zone, said driving means operating to move said cylindrical means at a velocity related to the yarn feeding speed as determined by the speed of said feed rollers.
