Adjustable Restraint Pad

The restraint pad of this paper feeding separator/restraint system is movable so as to be adjustable and to easily permit periodic replacement, as necessary, due to wear.

A sheet of paper 10 is driven to separator/restraint nip 11 by means not shown. Rubber-like separator roller 12 is driven in the direction of paper feed and cooperates with stationary restraint pad 13. This pad is resilient and operates to allow a single sheet of paper to be fed through nip 11. However, if more than one sheet is introduced to the nip, the sheets under sheet 10 are held back and only the top sheet 10 exits from the nip.

Pad 13 is supported by a curved metal plate 14. This plate is in turn pivotally mounted onto metal bracket 15 by two tabs 16 and a third tab 17, which movably mates with an adjustable bolt 18 carried by bracket 15. The open slots in tabs 16 and 17 facilitate rapid replacement of a worn restraint pad.

Bracket 15 is rigidly fixed in position. Rotation of roller 12 operates to automatically rotate plate 14 in a clockwise direction, until optimum interference is produced at nip 11. The maximum rotation of plate 14 is determined by adjustment of bolt 18. Preferably, bolt 18 is self-locking.

The end 19 of plate 14 is extended to comprise a counterweight which maintains pad 13 generally in its operative position.
