Abstract

939,337. Clicking knives. E. HOFFMANN. Aug. 31, 1962 [Sept. 4, 1961 ; Nov. 22, 1961], No. 33547/62. Class 31 (1). [Also in Group XXII] A clicking knife for cutting out shoe blanks comprises a template or core 1, of, e.g. press board, shaped to the part to be cut and secured by an adhesive, which remains elastic when dry, to the inner surface of a knife blade 2. Alternatively, a tape coated on both sides with an adhesive is used which is stuck around the periphery of the core prior to assembly within the knife blade 2. In another alternative, the core is surrounded by a metal band having a channel cross-section and the assembly retained within the knife by a metal adhesive. In order to obtain a wide contact surface for the adhesive the outer edge of the core is widened by splitting it in a longitudinal direction. Hollow punches 3 and perforators 4 and also drifts and knives (not shown) may be bonded to the core. The original template or a replica of same is used as the core.
