  • Patent number: 10689209
    Abstract: A noncontact support platform includes pressure ports distributed on a surface of a table, each connected to a pressure source. Vacuum ports are distributed on the surface of the table, each connected to a vacuum source. Outward flow through the pressure ports and inward flow through the vacuum ports form a fluid cushion to support a workpiece at a nonzero distance from the table. A plurality of channels each connect at least two of the vacuum ports to enable flow of fluid between the connected vacuum ports. When one of the connected vacuum ports is covered by an edge of the workpiece and the other is not, a suction force that is exerted by the connected vacuum ports on the edge is weaker than the suction force that is exerted on a part of the workpiece where both of the connected vacuum ports are covered.

  • Patent number: 10556767
    Abstract: A first leading end plate and a first rear end plate are provided at an upper part of a rotary table. When a conductor piece contacts the first leading end plate, a first contact detection sensor detects a contact of the conductor piece, and transmits a contact detection signal to a storage control unit. Upon receiving the contact detection signal, the storage control unit drives an air supply device for a predetermined period to spray air toward the conductor piece from a first air nozzle. The air spray brings the conductor piece into a tilted state with the rear end thereof moved downward. Even when the conductor piece contacts the first leading end plate and rebounds, the rear end thereof contacts an inner wall surface of the first rear end plate, thereby preventing the rear end of the conductor piece from getting over the first rear end plate.

  • Patent number: 9561671
    Abstract: A media transport system provides full vacuum under media as the media traverses an entire print path of an ink jet printer while simultaneously providing for a no-vacuum inter-copy gap that moves along with the media past print heads of the ink jet printer. This is accomplished with a dual vacuum inner/outer vacuum drum system that includes a first drum that has a matrix of holes that allows for full coverage of vacuum with a second underlying drum that is shifted to align a second set of holes to match the sheet pitch. By shifting the second drum in relation to the first drum, a combination set of holes is aligned to provide full vacuum across the media while a column of holes is blocked to provide a non-vacuum inter-copy gap.

    Abstract: A sheet supply system, for use in supplying overlapped sheets to an interfolder, includes a bed roll on which a web is cut into successive sheets. The sheets are supplied to a sheet supply passage leading to retard rolls, which overlap the sheets within the supply passage. The trailing portion of each downstream sheet bulges outwardly as the sheet is supplied to the supply passage. An air tube directs pressurized air into a volume within which the bulge in the downstream sheet is formed. The pressurized air prevents the leading portion of the upstream sheet from being drawn outwardly along with the trailing area of the downstream sheet, by counteracting a vacuum that results from outward movement of the trailing portion of the downstream sheet after it is released from the bed roll.

  • Patent number: 7384035
    Abstract: A configuration for generating blowing air or suction air, in particular a directing element in a sheet-processing machine, has a throttle path formed with vortex chambers. The vortex chambers generate vortex flows in a flow channel and they are formed by projections on just one side of the flow channel. This allows the element to be advantageously produced by molding, such as injection molding, thermo-molding, or stamping.

  • Publication number: 20040164480
    Abstract: Objects such as pieces of mail are stacked without significant contact therewith by producing laminar air flow over a surface which defines or parallels a desired movement path for the objects. The objects are placed and form a barrier between the laminar air flow and ambient air and movement such as turning an edge of the object to prevent impact on other objects and regulation of direction velocity an kinetic energy of the motion of the objects is regulated by the Coanda effect of the laminar flow. The object thus provides an acoustic barrier to reduce generation and propagation of noise by the high pressure air used to create the laminar flow. An air amplifier reduces the volume of high pressure air required to provide control of object motion.

  • Patent number: 6755009
    Abstract: A method for making and handling an improved intraoral x-ray film packet by forming a first outer and a second outer sheet from a thermoplastic material wherein the first outer sheet is made more rigid than the second outer sheet such that it has a tensile modulus of at least about 700 Kg/cm2. The two outer sheets are sealed together to form an envelope with a laminated perimetric edge wherein the laminated perimetric edge is substantially coplanar with the first outer sheet. This resultant planar surface on one side of the packet aids in the accurate positioning of the packet for subsequent operations and further enhances the ability to die cut the packet and maintain outside dimension tolerances. Individual film packets are transported to a Bernoulli fixture and a laminar air flow is generated across the surface thereof to accurately position the intraoral x-ray film packet against reference stops using the Bernoulli effect.

  • Patent number: 6606946
    Abstract: A sheet offset printing method and a sheet offset printing press includes altering flow relationships in an interior of a housing of a sheet delivery of a sheet-fed printing machine to prevent uncontrolled spread of powder in the housing by extracting powder-laden air from the housing and/or feeding air into the housing from outside at a point along a return belt of a sheet conveying device. Air currents are channeled inside the housing by feeding air not laden with powder into the housing and/or leading the air into an air flow path along the return belt downstream of the point with respect to a return belt motion direction to transport the unladen air toward a printing unit by a drag effect of the return belt and/or impeding/blocking a supply of powder-charged air from around a conveyor belt of the sheet-conveyor or a powder-scattering device into a flow path along the return belt.
