Abstract
974,112. Perforating plastic &c. materials. J. V. ABOM. May 5, 1961 [May 9, 1960], No. 16373/61. Heading B4B. A method of perforating thin sheets of synthetic plastics and like material comprises placing the sheet material 1 on to a smooth backing 2 and forcing a punch 3 through the sheets in such a way that the punched-out material is pressed into a recess formed in the backing by the punching operation. The backing or die 2 can be formed of wood, layers of paper over wood, rubber, plastic material, cork, leather or some soft metal such as tin and lead. In the embodiment shown in Fig. 3, plastic sheeting 1 to be perforated is wrapped several turns around a roll 7, and a plurality of punches 3 are radially mounted on a wheel 8 which is adopted to perform the punching operation by co-operation with the roll 7 as the latter is rotated. The wheel and roll may be moved axially relative to each other at a predetermined rate, such movement being intermittent and only when the punches are clear of the sheeting. The punches are preferably of involute gear tooth profile.
