ABSTRACT:
Apparatus is provided for preventing a sheet drooping during sheet feeding in a first direction in a generally horizontal plane where a sheet is not entirely supported by a conveyor. A rod is mounted below the plane, having at least one collar with a support pin extending radially outwardly from the collar making an engagement angle of about 55-85 with respect to a second plane parallel to the horizontal plane and passing through the rod. The position of the support pin with respect to the rod may be readily adjusted, both the angle with respect to the second plane, and along the rod. Adjustment of the position of the collar with respect to the rod, in both modes, may be provided by a screw threaded fastener extending in a screw threaded bore intersecting the rod, and about 90.degree. circumferentially spaced from the support pin. The support pin may have a truncated cone end with a rounded tip at the end for engaging a sheet. Also the position of the rod with respect to a feeding conveyor may be adjusted, as by using notched side plates that the rod fits in and is stabilized in so that it does not rotate with respect to the side plate.
