    Abstract: A vacuum roller assembly adapted to singulate a sheet from a stack of sheets. The vacuum roller assembly comprising a stationary inner plenum having a substantially linear plenum slot disposed in fluid communication with the vacuum source and a rotating vacuum roller disposed over the stationary inner plenum and rotating about a rotational axis. The vacuum roller includes a plurality of apertures disposed in fluid communication with the substantially linear plenum slot and about the periphery in at least one region of the roller. Furthermore, each of the apertures is substantially slot-shaped and defines a major axis. The major axis is off-axis with respect to the substantially liner plenum slot of the inner plenum to reduce audible noise levels produced by the rotating vacuum roller as air flows through each rotating aperture into the stationary linear plenum slot.

    Abstract: An image recording apparatus of the present invention includes a conveyance mechanism having a circumferential wall. On the circumferential wall are formed suction holes which communicate an internal space inside the circumferential wall with the outside of the circumferential wall. A recording medium is placed on the outer circumferential surface of the circumferential wall, and is conveyed on the outer circumferential surface in a direction of the rotation of the circumferential wall. A suction unit sucks the air in the internal space to create an air flow from the outside of the circumferential wall to the internal space via the suction holes. A recording medium ejection path branches off from the outer circumferential surface at a separating position which is at the most downstream position of a record head or a position further from the supply position S1 than the most downstream position from the supply position. A blocker positioned in the internal space successively faces an inner opening of at least one of the suction holes having reached the separating position with the movement of the circumferential wall, so as to block the inner opening of the at least one of the suction holes.

    Abstract: An apparatus for removing slip sheets from printing plates has two concentric cylinders that are mutually rotatable about a common axis. Suction exerted via two elongated slots separates a deformable sheet from a relatively rigid object to which it is adhered. The deformable sheet is drawn into a recess presented by the two aligned slots. The concentric cylinders are then rotated to grip the deformable sheet between opposing edges of the slots.

    Abstract: A vacuum holddown has a holddown member with an outer surface for temporarily capturing a flexible sheet material via a vacuum force distributed across the outer surface through discrete vacuum channels. A vacuum force valving mechanism abuts an inner surface of the holddown member in a selectable sliding engagement. The valving mechanism has a pattern of apertures therethrough in predetermined pattern such that discrete valve mechanism positions produce discrete vacuum force patterns at the outer surface of the holddown member.

    Abstract: The draw-roller unit has only one suction roller (20b, 21b) as a draw roller, in which a constantly acting suction effect is effective along that circumferential portion round which the paper web is looped, whilst the remaining circumferential portion experiences no suction effect. The suction roller has a fixed hollow roller core (65) and a roller casing (61) rotatable about this and consisting of plastic-impregnated carbon fibres, with suction ports (62) distributed over its circumference. The roller core (65) is equipped, on its one side, with an axial connection piece (68b) for fastening to the machine stand and for connection to a vacuum source, on its other side with a bearing journal (66) and, on its circumference having passage orifices (70) with two radial partition walls (69) which are arranged at a specific angular distance from one another and which enclose a suction chamber between them. The roller casing is mounted on the bearing journal (66) a conical connecting flange (61b) fastened directly to the rotor shaft of the drive motor and is mounted with its other end on the connection piece (68b), the gaps between roller casing and partition walls (69) being approximately airtight. Instead of a suction roller, a draw roller subjected to compressed air on the outside along the circumferential portion can also be provided, or else the suction-air and compressed-air effects are combined.

    Abstract: A vacuum roll includes an inner rotor, an intermediate stator, and an outer shell roll. The inner rotor has open and closed portions and is adapted to rotate within the intermediate stator which is rotationally fixed and also has open and closed portions. The outer shell roll has open and closed portions and is adapted to move around the intermediate stator. Together the inner rotor and the intermediate stator define an internal rotary valve interface adapted to control fluid communication between the interior chamber and the outer shell.
