DISPOSITIVO PER RIFILARE IL BORDO NON CUCITO DI UN MANUFATTO TUBOLARE PROMA DELLA CUCITURA DI UN TASSELLO PECIALMENTE IN MACCHINA PER APPLICA E UN TASSELLO A CALZAMUTANDA PER SIGNORA

摘要

A device for trimming an edge of a tubular article to form a portion of a pantyhose prior to the sewing of a gusset. A support is rotatable about its vertically disposed central axis and cooperates with a mask supported independently of the support and normally stationary. The mask has slots with which trimmers in the form of electrical heating elements cooperate, each of the trimmers being movable independently of the other relative to the mask. The support is rotated relative to the mask and one of the trimmers penetrates and cuts the cloth by heat action and enters one of the slots in the mask so that during continued rotation of the support an edge of the article is trimmed from the remainder by the aforesaid trimmers to remain engaged about the support as an annular band. Rotation of the support is then stopped and the other trimmer is extended towards the mask to penetrate the annular band and enter the other slot to sever the annular band by heat action and convert the band into an elongate ribbon which is then drawn off into a suction duct having a mouth mounted for movement with the other trimmer.
