    Abstract: The specification discloses a sheet feeder in which the sheets are driven by one-way rotatable friction rollers mounted on a lever freely pivotably mounted on a reciprocable support, the height of the pivot of the lever being adjustable to vary the angle of inclination of said lever to the horizontal to adapt the sheet feeder for feeding different weight sheets. The pivot of the lever may also be adjustable forwards and backwards to adapt the feeder for different sheet sizes and thicknesses of paper.

    Abstract: A method and device for loading an offset master on to the plate cylinder of a rotary duplicating machine. Liquid adhesive is applied to the tail of the master prior to loading thereof, on the side which after loading contacts the master cylinder of the duplicating machine, so that the tail of the master is prevented from flapping and thereby becoming damaged. The invention is suitable for use with any form of rotary duplicating machine having an automatic clamp for engaging the leading end of a master being loaded.

    Abstract: Printing apparatus including a movable sheet sensing member cooperable with a driven slotted sheet deflector member so that a passing sheet in contact with said deflector member will cover the slot and cause the sensing member to be urged into a sheet present position to disenable the pressure roller raising mechanism. Absence of a sheet permits the sensing member to enter the slot and thereby remain in a sheet absent position.
