Abstract
675,710. Rotary punching-machines. HOMANN AKT.-GES., F. Jan. 17, 1951 [June 30, 1950], No. 1308/51. Class 31 (ii). A punching-machine comprises a plurality of twist spindles 9, provided with punches 46, which are retained against axial movement by ball-bearings 39, 43 between plates 7, 8 and are rotated by means of screwed nuts 53 held in a plate 5 attached to a carrier 4 which is recipro. cated vertically by mechanism comprising cams 13, 14 and connecting rods 17, 18, the work being carried on a platen 21 which is moved towards and away from the punches by means of a cam-operated ram 22. One or more stops 33 for positioning the work are adapted to be raised to pass through the platen by means of a cam-operated control device 30, 32.
