Abstract

To compensate for curling, warping, or an unlevel paper stack, the shingler arm, shown in Figs. 1 and 2, is allowed to pivot or float on a stack of sheets. For the present rotary shi-ngler (single arm with two rollers), it is only necessary to allow pivoting motion in one direction and a pin joint will suffice. Several designs are possible; the pin joint mentioned is one. Because of the need for the pivot pin coming through the center shaft, a ball and socket type of a joint with a slot cut into the arm to allow clearance for movement was designed. A retaining screw holds the assembly together.

Self Aligning Rotary Shingler

To compensate for curling, warping, or an unlevel paper stack, the shingler arm, shown in Figs. 1 and 2, is allowed to pivot or float on a stack of sheets. For the present rotary shi-ngler (single arm with two rollers), it is only necessary to allow pivoting motion in one direction and a pin joint will suffice. Several designs are possible; the pin joint mentioned is one. Because of the need for the pivot pin coming through the center shaft, a ball and socket type of a joint with a slot cut into the arm to allow clearance for movement was designed. A retaining screw holds the assembly together.

Other design ideas include moving the pivot joint up the shaft to avoid going through the pivot pin, using a flexible joint between the shaft and arm, or using a flexible shingler arm. Also, a cylinder and groove joint is acceptable.
