发明名称 Apparatus for use in trimming molded records
摘要 An apparatus is disclosed for trimming flash from molded thermoplastic records. The records which are advantageously trimmed using the apparatus of this invention have the flash secured to the outer diameter of the molded record with a web having a thickness which is substantially less than the thickness of the molded record and the principle portion of the flash. The apparatus of this invention has a rotatable turntable means for holding a record to be trimmed and a focused infrared heating means positioned relative to the turntable so as to selectively heat and soften the web prior to trimming. The softening of the web facilitates trimming the flash and the final finishing of the molded thermoplastic record.
