ABSTRACT:
The present invention provides a pin-feed apparatus suitable for use in a recording system, including pin-wheels adapted to operatively engage perforations on a sheet to be carried through the recording system, at least one of the pin-wheels being adjustably movable away from and toward the other pin-wheel in the direction of sheet width by resilient engagement of openings with spring pieces, at least one of the openings having such a size that it provides a play when that opening is engaged by the corresponding spring piece.
