Abstract

457,946. Printing-machines. RIDDER, J. DE, 22, 4th Avenue, and BRILL, W. G., 100, 4th Avenue, Melville, Johannesburg, South Africa. Sept. 5, 1935, No. 24718. [Class 100 (i)] Perforating - apparatus.- In a device for perforating paper sheets simultaneously with the printing thereof, the perforating blade is actuated to change its position as the pressure member of the printing - machine recedes after the printing operation so that the blade is set for the next printing operation. In one form, the blade 1 is pivoted on a rod 2 and is urged towards its inoperative position by a helical spring 5. It is raised to operative position by a lever 6 carrying a roller 7 at one end bearing against a tapered plate 8 on the blade. At its opposite end 17, the lever projects between pins 18 on a disc 15 rotated step by-step by a ratchet-and pawl device 12, 14, so as to oscillate the lever 6. The operative stroke of the device 12, 14 occurs as a plunger 10, which is depressed by the printing-platen and carries the pawl 12, rises under the action of a spring 11. A spring- pressed retaining pawl 14a is provided for the disc 15. In another form, arranged to leave every third printed sheet unperforated, the end 17 of the lever 6 has a pin engaging a cam groove in a disc rotated by the ratchet device. The blade may be carried by parallel links operated by a lever engaged by the pins 18 on the disc 15. Also, wedge devices may be used to raise the blade. The mechanism operating the blade is arranged to give the required sequence of perforated and unperforated sheets.
