Abstract:  
Matter enclosed in heavy brackets [ ] appears in the original patent but forms no part of this reissue specification: matter printed in italics indicates the additions made by reissue. This invention relate to methods and means for removing flashings and fins or the like or otherwise trimming molded rubber parts; and more particularly to improvement in methods and machines for such purposes using the technique of first "freezing" the parts so as to render the flash or fins brittle and therefore susceptible to a flasing or fin removing operation.
