Title: Stencil printing apparatus
Inventor: SUZUKI ATSUSHI
IPC: B41L13/18
Filed: 2000-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a stencil printing apparatus which can deliver printing sheet stably.

This device is controlled so that V3<=V4 be established when the peripheral velocity of the delivery cylinder 11 is made V3 and the carrying speed of the carrying device 60 V4.  Since the nipping forces of the delivery cylinder and the pinch roll are stronger than the carrying force of the carrying device, the carrying speed of the printing sheet is equal to the peripheral velocity of the delivery cylinder until the rear end of the printing sheet passes through the pinch roll. When the rear end passes through the pinch roll, the carrying device can carry the printing sheet, holding it stably by suction. The speed of delivery can be made high even when the number of revolutions of the delivery cylinder is small, while an effect such as rubbing of an image is not produced even in low-speed printing, and stable delivery can be performed.
