Abstract

991,052. Perforating apparatus. IBM UNITED KINGDOM Ltd. April 16, 1964 [April 22, 1963], No. 15815/63. Heading B4B A holder for use in removing punched-out portions from a pre-scored record card 22 in predetermined index positions by means of a manually held punching tool comprises a plurality of T-shaped rubber backing strips 15 supported in grooves in bars 13 extending between the ends 12 of a frame 10 of syntheticresin and a panel 18 slidably mounted in the frame whereby punched-out portions of the card may be removed. The bars may be attached to, or moulded integrally with, the frame and a reinforcing bar extending across the frame beneath the mid-points of the bars is also moulded integrally with the frame. One end of the frame is cut away and the other end and the sides of the frame are provided with a lip 23 to retain the card on the backing strips. A perforated transparent plastics card may be inserted in the frame above the record card to guide the punching tool. Specification 846,212 is referred to.
