Abstract

A shingler wheel for feeding paper from a stack comprises a plurality of rollers spaced about the periphery of the wheel. In order to avoid concentration of the roller-to-paper impacts at a single frequency the rollers are unevenly spaced.

Shingler Wave Generator Design

A shingler wheel for feeding paper from a stack comprises a plurality of rollers spaced about the periphery of the wheel. In order to avoid concentration of the roller-to-paper impacts at a single frequency the rollers are unevenly spaced.

Fig. 1 shows a shingler wheel 10 mounted on a shaft 11 for rotation therewith. A series of rollers 12 are supported at the periphery of the wheel and engage a stack of paper 14. The rollers each impact the stack of paper and roll across it, thereby urging the paper forward. The rollers are spaced unequally about the wheel so that consecutive impacts of the rollers with the stack do not occur at a common frequency.

Fig. 2 illustrates the amplitude vs. frequency curves 15 for unequally spaced rollers and the single higher amplitude curve 16 for equally spaced rollers.
