Abstract

350,949. Paper-folding machines. HOE & CO., Ltd., R., QUICK, C. G., and WHITEHEAD, W. A., 109, Borough Road, London. March 17, 1930, No. 8581. [Class 100 (ii).] In paper-folding mechanism in which the sheet is tucked by a blade 19 between gripper jaws 4, 5, the jaws are operated by a toggle-lever mechanism adapted to be moved into dead centre position to cause the jaws 4, 5 to grip the paper. In one form, as shown in the Figure, the jaw spindles 27, 30 are geared together and are operated by means of toggle levers 23, 24, the shaft 22 of the lever 23 carrying an arm 21 having a roller 11 running in a cam groove on the cylinder 1. When the levers 23, 24 are moved into straightened position to close the jaws 4, 5, the cam groove is relieved of the direct pressure required to hold the jaws closed and the wear thereon is therefore reduced. In order that the gripping action may be resilient, the lever 24 passes freely through a swivelling block 25 on the jaw 4 and springs 16 on the lever bear against the block 25 and an adjustable stop on the lever. In a modified form, the arm 21 is dispensed with and the roller 11 is situated at the joint of the levers 23, 24. The resilient connection 16, 25 is omitted but a spring-pressed rod is provided tending to keep the jaw 5 pressed against the jaw 4, which is provided with a cam part engaging the jaw 5 so that both jaws are opened simultaneously by the toggle mechanism against the spring action.
