Abstract

When documents such as money, in a transport employing rubber surface roller, can be transported in either direction, it is often desirable to maintain the document against one side of the transport so as to hold it in a registered position for delivery from the transport. This article shows a single pivoting skew wheel which provides registration regardless of the document direction. As shown in the figure, a skew wheel 11 is driven by a drive wheel 13 through a document 15, shown in dotted lines. Skew wheel 11 is mounted on a shaft which pivots on pivot point 17. When the document is moving toward the left, the friction of the skew wheel 11 on its journal causes the entire axle to pivot around pivot point 17 in a clockwise direction. Document 15 is thereby continuously urged against registration rail 19.

Pivoting Registration Roll for Bidirectional Registering Sheet Feed

When documents such as money, in a transport employing rubber surface roller, can be transported in either direction, it is often desirable to maintain the document against one side of the transport so as to hold it in a registered position for delivery from the transport. This article shows a single pivoting skew wheel which provides registration regardless of the document direction. As shown in the figure, a skew wheel 11 is driven by a drive wheel 13 through a document 15, shown in dotted lines. Skew wheel 11 is mounted on a shaft which pivots on pivot point 17. When the document is moving toward the left, the friction of the skew wheel 11 on its journal causes the entire axle to pivot around pivot point 17 in a clockwise direction. Document 15 is thereby continuously urged against registration rail 19. Stop 21 prevents skew wheel 11 from rotating more than a few degrees, sufficient for registration without inhibiting document movement. If the document is moving toward the right, friction again causes skew wheel 11 to rotate with its axle around pivot point 17 for a small angle until the axle engages stop 21. Right traveling documents can now be urged against registration rail 19 in the same manner as left traveling documents.
