Method and device for processing winding end of thermoplastic resin sheet
专利汇可以提供Method and device for processing winding end of thermoplastic resin sheet专利检索，专利查询，专利分析的服务。并且PURPOSE: To ensure locking of a winding end by melting and securing together the winding end and a layer subsequent to that of the winding end, by a method wherein a sheet winding end portion is pressed by a press plate, a plurality of heater needles are inserted down to depth being at least one layer or more of the winding end for heating.
CONSTITUTION: A thermoplastic resin sheet conveyed on a conveyer 3 is wound on an arm 16 around a winding core 12 being vertically rockable. Upon completion of winding, a heater mechanism 21 is lowered, and a press plate 25 mounted to a heater mechanism 21 is brought into contact with a wound sheet 2A. When a winding end 2B is perceived by a sensor 44, the wound sheet 2A is stopped, and the winding end 2B is situated to a home position. The wound sheet 2A is pressed by the press plate 25, a plurality of heater needles 23 are lowered from a heat feed device 22 of a heater mechanism 21 through insertion holes of the press plate 25, and are pressed down to a subsequent layer through a layer in the vicinity of the winding end 28. After heating, the heater needles 23 are pulled off, and the press plate 25 is then raised. Thus, the winding end and the subsequent layer are thermally dissolved for securing.
