Abstract: The present subject matter relates to systems and methods for advancing booklets from a group of booklets are provided. In particular, a booklet feeder can include a conveying path for supporting a group of booklets with each booklet comprising a stack of bound sheet articles, and a grip remover configured for engaging booklets in a seriatim manner in the conveying path. The grip remover can be movable to remove an engaged booklet from the conveying path and advance the removed booklet to an exit path.

Abstract: An accumulator apparatus for accumulating one or more sheets or articles is provided and includes a sheet accumulator portion for accumulating one or more sheets or articles, a ramp disposed upstream of the sheet accumulator portion relative to a flow direction of the sheet or article, an actuator and a pusher plate connected to the actuator. The actuator is configured to move the pusher plate away from the ramp in a direction toward a sheet accumulation portion of the accumulator apparatus.

Abstract: A fold roller locking adjustment mechanism for a folder, and in particular a buckle folder. The invention eliminates unintended changes to roller gap in a buckle folder by reducing the effect of machine forces on the fold roller support and adjusting mechanism.

Abstract: A positive drive mechanism for use in a sheet folding apparatus includes a motor drive, a torque-limiting device coupled to the motor drive, a drive pulley coupled to the torque-limiting device, and a plurality of idler pulleys. Each of the idler pulleys is coupled to a drive shaft which supports a fold roller. A non-slip positive drive member operatively engages portions of the drive pulley and the plurality of idler pulleys. A sheet is fed into the folder and between the fold rollers in order to fold the sheet. In the event that the sheet becomes jammed between the fold rollers, the torque-limiting device operates to release the torque transmitted from the motor drive to the drive pulley.

Abstract: A wallpaper work belt and accessories including an adjustable waist belt having various tool holders disposed thereon. Tool holders include a smoothing brush holder for right or left handed dispositions, a seam roller holder, a specialized edger, and a cleaning cloth holder. An angular disposition of the smoothing brush holder facilitates insertion and extraction of the smoothing brush during use. The smoothing brush holder and edger holder are detachably affixed to the waist belt and may be removed and cleaned using conventional hot water cleaning techniques.

Abstract: An articulated document feeder and diverter which allows pivoting and rotation about two mutually perpendicular axis of rotation to thereby allow idle rollers mounted on a pivotable carrier to maintain contact with drive rollers, whether a divert pivoting occurs or not. Compliance members, preferably resilient O-rings mounted on the periphery of the idle rollers, help to absorb unevenness in the contact face between an idle roller and a drive roller/s/.
