ABSTRACT:
This invention pertains to the type of apparatus for handling sheets shown in U.S. Pat. No. 3,658,322 and particularly to the take-off conveyor on such apparatus on which the direction of the sheets issued from the sheet making machine is changed toward a stacker. The improvements pertain to the accurate adjustment of the back-up means on the take-off conveyor to correspond to the length of the sheets delivered from the sheet making machine thereby to allow accurate stacking of the bundles of sheets on the take-off conveyor; the adjustability is accomplished through a suitable selector dial on circuit control device which is calibrated for the length of the sheets and which when set to the particular length then through an electric circuit and driving mechanism moves the back-up abutments to that selected measurement accurately and automatically; another improvement is the adjustability of the snubber device at the discharge end of the take-off conveyor for adjustment to the thickness of the bundles of sheets; a further improvement includes adjustable snubbers on the layboy at the intake of the stacker device for adjustment to the width of the sheets for the proper transmittal of the sheets to the stacker conveyor.
