Abstract

627,803. Sliding-clasp fastenings. WINTERHALTER, M. June 24, 1947, No. 16649. Convention date, July 6, 1946. [Class 44] [Also in Group XXII] In making elements for sliding-clasp fastenings a strip 4 is intermittently fed through a machine with tools which shear the end 24 of the strip, cut out a portion 251 and form a locking projector 28. The tool comprises members 1, 2 guided as a sub-press mechanism by posts 23 and carrying a punch 9 co-operating with a die 12 for forming the projection 28, and a punch 10 with edges co-operating with dies 13, 14 for shearing on the edges 24, 25<SP>1</SP>. The strip is fed intermittently under a plate 3, the waste portion drops down a shoot 34 and the elements are fed down a passage 27 and are secured to the tapes by legs 26. Specifications 558,427 and 570,862 are referred to.
