Abstract

PURPOSE:To improve the ability of cutting a linear object composed of continuous resin hair, by winding it up in a U-shape state from a supply means by a turning roller between two continuously turning holding drums, and cutting it with a cutter and rounding off the cut end. CONSTITUTION:A resin linear object 1 is pulled out from a guide tube 26 by a motor 21 through a supply means 11, guide rings 18, 24, a traverser 23, and a guide 25. A take-in means 20 includes: take-in drums 27, 27 which rotate on both sides of a pair of right and left resin hair holding drums 12 simultaneously with the drums 12; a number of take-in pins 28 in the circumferential direction of the periphery of the drums 17 to wind up the resin hair 1 by making a U-turn. Then, the take-in pins are made to sink, the resin hair 1 in the U-turn state is transferred onto the holding drum 12, and the U-turn part is cut off with turning teeth 35, 35 of a cutter 13. Cut-off pieces are successively fed to a holder groove 31, guided to a heater 14 where the cut ends are rounded off, and taken out from a discharge means 15 collectively by a fixed amount. This enables noiseless cuttings continuously and efficiently.
