Sheet Stacking, Unstacking Or Handling Patents (Class 118/236)
  • Patent number: 9676573
    Abstract: A sheet handling apparatus comprising a rotary drum having an outer peripheral wall with perforations, and a number of separate chambers, a suction system for controlling a flow of air through the perforations, thereby to attract sheets to the peripheral wall of the drum, and a stationary shutter member for blocking the flow of air through the perforations when they pass through a predetermined angular range. The number of separate chambers extend in axial direction and are distributed over the periphery of the drum. A disk-shaped manifold at the first axial end of the drum is co-rotatably with the drum. The manifold forms a number of radial channels each connected to one of said chambers and having an opening at a radially inward end of each channel. The stationary shutter member is arranged for blocking an opening of a channel to block air flow from a radially inward end of a channel.

  • Patent number: 7966931
    Abstract: A sheet-fed offset printing press prints multiple colors on both sides of sheets, preferably on sheets of paper. A first row of in-line printing units print a first side of the sheet, before the sheets are turned in a reversing device, which is followed by a second row of in-line printing units for printing the other side of the sheets. The second row of in-line printing units is followed by one or more varnishing units that are arranged in such a way or include varnishing blanket cylinders that are arranged in such a way that the front sides and the back sides of the passing sheets are varnished.

  • Patent number: 7387818
    Abstract: When stacking stackable items in layers on pallets, intermediate layers of paper/cardboard/film are often used for preventing loss of the items during transport. Even though the intermediate layers ensure to a large extent that items do not fall off the pallet, it cannot be entirely prevented that some of the stacked items fall off because the stacked items slid on the intermediate layers. Special intermediate layers are known, having a surface coated with non-skid coating which highly counteracts the unwanted sliding of the items in the layers stacked on a pallet. However, the laying of intermediate layers with non-skid surfaces constitutes a problem as the individual pieces of non-skid coated intermediate layer will adhere to each other. Thus, there is provided a method and a sheet dispenser where pieces of intermediate layers are successively dispensed, and where these layers are coated with a non-skid coating during dispensing.

  • Patent number: 6579364
    Abstract: Sheet products, such as card stock, envelopes and other paper products (10) are advanced on a vacuum surface conveyor belt (30) beneath a glue applicator drum (35). The glue transfer strips (37 and 38) of the glue applicator drum apply stripes of glue (42 and 43) at the ends of the sheet product, leaving a belt engaging space (41) without glue between the glue stripes. The sheet product is grasped by overlying conveyor belts (46 and 47) at the belt engaging space (41), thereby exposing the wet glue stripes on opposite sides of the belts. Hot air is applied on opposite sides of the conveyor belts (46 and 47), drying the glue. The glue transfer strips (37 and 38) of the glue applicator drum can be adjusted in size, shape and position so as to apply glue to one end, the other end, or both ends of the sheet product, and if glue is applied to only one end, one of the dryers (50 or 51) can be deactivated, saving energy.

  • Patent number: 5439704
    Abstract: A powder coating line for coating either coiled strip or pre-sheared and punched blanks is provided. In order to coat strip a catenary portion of the strip is suspended through a powder coating subsystem which includes a powder coating booth and a curing oven. The coated strip is the recoiled onto a rewind reel. In the alternative, the strip may be stopped and sheared at an input region and presheared blanks introduced to the powder coating subsystem. The blanks are placed on a belt conveyor, which transports them into the powder coating booth. The blanks are then passed in a conveyor through the powder coating booth and over for subsequent restacking. After passing out of the oven, and before coiled or stacking occurs, the strip or blanks pass through a quench and an air dryer. The powder coating subsystem can be incorporated into a larger pre-treating, cleaning, embossing or post-processing line.

  • Patent number: 5421887
    Abstract: A method and apparatus for sequentially applying a predetermined amount of adhesive to a series of sheets of insulation having a frame with a conveyor mounted at one end, a magazine adapted to maintain and dispense sheets of insulation, one at a time onto the conveyor, a floating adhesive dispensing hopper is positioned adjacent to the conveyor, and a sheet stopping mechanism located on the other side of the hopper at the opposite end of the frame. In operation, a plurality of sheets of insulation are loaded into the magazine, dispensed onto the conveyor one at a time, then driven by the conveyer under the floating adhesive dispensing hopper which applies adhesive to the entire width of the sheet of insulation as the sheet passes under the hopper. The stopping mechanism beyond the hopper stops the movement of the sheet of insulation by deactivating the conveyor until the sheet with the adhesive applied thereon is removed.

  • Patent number: 4643130
    Abstract: Apparatus for forming matchbox skillets from pre-printed sheets, each sheet having a plurality of rows of matchbox blanks printed thereon. The apparatus includes a sheet feeder for storing pre-printed sheets and removing the sheets one-by-one. The sheets are fed to a gravure printing machine, which applies stripes of striking compound material to predetermined areas of the sheets as they pass therethrough. A conveyor is provided for conveying the sheets from the sheet feeder to the gravure printing machine. After leaving the gravure printing machine the stripes of striking compound material are dried in a radio frequency drier. The sheets are then cut into matchbox blanks by cutting machines. The gravure printing machine has an upper engraving roller, a lower pressure roller, and means for feeding the sheets between the two rollers so that the stripes are printed on the upper surface of the sheets in register with the matchbox blanks.

  • Patent number: 4530306
    Abstract: A device which provides an economical means for coating offset plates on one side with a solvent based coating. An offset plate is advanced along a feed table by a suction belt toward a roller assembly consisting of a fountain roller, a metering roller, a coating roller and an impression roller. The fountain roller transfers liquid from a supply of coating liquid to the metering roller which transfers a predetermined amount of liquid to a moving plate by the coating roller. The impression roller forces the plate into engagement with the coating roller. A photoelectric sensor detects the leading edge of the plate as it moves through the roller assembly and moves the impression roller toward the coating roller to begin the coating application. The sensor detects the trailing edge of the moving plate and retracts the impression roller to stop the coating application. The speed of the feed belt, discharge belt and rollers are synchronized to accurately control the thickness of the coating applied to the plate.
