IPC: B42C19/00
Filed: 1985-07-11
Abstract: PURPOSE:To obtain improved finish of binding in a binding device for a copying machine or the like by feeding papers one by one to a folding station by a pair of delivery rollers, and releasing the pressure between the delivery rollers after the paper is held between folding rollers. CONSTITUTION:A paper P from a paper supply station is delivered by rollers 6 and passes on a sponge roller 12 rotating in contact with an upper guide plate 8, and when the leading end of the paper comes in abutment against a fence, the paper begins to be bent in the vicinity of the rollers 6 and a lower guide plate 9. At this time, a roller 7 in form of a cylinder having a cutout portion so as to come in contact at a part of the external surface thereof with the roller 6 rotates a single turn synchronously with a sensor signal, so that, when the rollers 6, 7 begins to come in contact with each other, they seize and fold the bent portion of the paper therebetween. During this single turn, the delivery force of the rollers 6, 7 is momentarily lost at the cutout portion, and thereafter the pressure between the delivery rollers 6 is released. This permits smooth delivery of papers and good finish of binding.

Thereby, the gravel walls formed at the periphery of the outer frame of a double frame structure being formed of the inner frame and the outer frame are destroyed while sediment is being made to flow out from its place of sedimentation to the downstream side of the dam through the double frame and the weep holes, and sediment discharge function is restored.
