发明名称 Method for manufacturing multicolor slide fastener, and apparatus therefor
摘要 Apparatus for manufacturing a multicolor slide fastener includes an upper die 110, a lower die 120, and a plurality of unit fastening teeth-forming slots 101 formed in a lengthwise direction. Molding material-injecting passages and a plurality of sprue holes 102 are provided for injecting the molding materials S into the slots 101. Inclined passages 201 and 202 are connected to the molding material injecting passages respectively, for carrying the molding materials S from a raw material source. Heaters 240 and heat sensors 241 heat the passages 201 and 202. Pressing means 300 press the molding materials S into the inclined passages 201 and 202. Valves 400 control injection of the molding materials S into the sprue holes 102 of the upper die 110.
