摘要： In order to permit automated setting of operating parameters while also facilitating the removal of paper jams, a device for adjusting the gap size between folding rollers (16,18) of a rotary press folding machine includes a pair of counter-rotating folding rollers (16,18) which define a folding nip or gap (17) therebetween. Each folding roller (16,18) is mounted to one end of a pivoting support arm (20,22), and a link arm (48,50) is slidably and pivotably mounted to the other end. An extensible member (78) connects the link arms to each other, which enables the distance between the rollers (16,18) to be quickly and easily adjusted. An inflatable bag (36) is disposed between the support arms (20,22) which forces the rollers (16,18) towards each other to resist spreading of the rollers (16,18) when a paper passes through the gap (17) between the rollers (16,18). The bag (36) can be quickly deflated from a remote location to allow removal of jammed papers, and can be quickly re-inflated to the desired setting to minimize down time. A control system (86) controlling both the extensible member (72) and the inflatable bag (36) permits rapid adjustment of the folding machine to accomodate changes in paper thickness.

摘要： Web feed apparatus , for example in web printing and folding apparatus, has a pair of opposing rollers, one (28) on a fixed axis and one (22) laterally movable to define an adjustable nip gap between their peripheries. The gap is automatically set and adjusted by a setting screw (4) driven by a servo motor (60) with rotation of the screw monitors by a potentiometer sensor (64). A stop collar (52) on the screw limits axial displacement thereof to determine the set nip gap and a spring (50) urges the rollers towards each other but permits displacement under overload conditions. A rectilinear sensor (54) senses said conditions by monitoring relative displacement by of the stop collar and a programmable control system processes signals from the sensors and operates the servo motor accordingly.
