An apparatus for overlapping and stacking sheets, the apparatus has a housing defining a stacking area and a travel plane for the sheets, a conveyor for transporting the sheets through the housing in a travel direction along a travel plane, and an overlapping device in the housing upstream of the stacking area for producing an overlapping stream of the conveyed sheets. A brake in the overlapping device slows the conveyed sheets of the overlapping stream. Stacking elements include stops projecting upward in the stacking area and serving to position a stack formed by the conveyed sheets of the overlapping stream. A separate frame carrying the stacking elements in the stacking area above the travel plane or extending to above the supply travel plane is mounted in the housing of the apparatus so as to be movable horizontally downstream in the direction away from the overlapping device.

Belt conveyor system comprising: an endless mesh belt, the belt having a mesh structure and having edge areas at the lateral sides, a drive mechanism drivable by a drive motor to rotate the belt, and a steering roller for steering the lateral position of the belt, wherein an edge area comprises a band running substantially parallel to the lateral sides, the band comprising an elastic filler being provided inside the mesh structure, the elastic filler being discernible from the mesh structure, and wherein the belt conveyor system further comprises a band position detector for detecting the lateral position of the band.

A post-processing device includes an output unit that outputs a medium; a stacking unit on which the medium that is output is stacked; and a blow-out unit that is disposed below the output unit and that blows gas toward the medium that is output, wherein an amount of the gas blown varies in a width direction that crosses a direction in which the medium is output.

A post-processing device includes an output unit that outputs a medium; a stacking unit on which the medium that is output is stacked; and a blow-out unit that is disposed below the output unit and that blows gas toward the medium that is output, wherein a direction in which the gas is blown differs in accordance with a type of the medium.

A sheet conveying system includes an upstream conveyor section having an endless first conveyor belt movable in a first conveying direction x and extending in a first lateral direction z, the first conveying direction x and the first lateral direction z defining a first conveying plane xz; and a downstream conveyor section having an endless second conveyor belt that adjoins the first conveyor belt and is movable in a second conveying direction x′ and extends in a second lateral direction z′, the second conveying direction x′ and the second lateral direction z′ defining a second conveying plane x′z′. The conveyor sections are adapted to hold the sheets slip-free on the first and second conveyor belts. The second conveyor belt has a shear compliance in the second conveying plane x′z′ that is larger than the shear compliance of the first conveyor belt in the first conveying plane xz.

It is aimed to provide a conveying device for absorbent articles capable of precisely sorting an absorbent article between a main conveyance path and a branch path and a conveyance method using the same. A path switching means includes a belt conveying unit with a conveying belt arranged along an annular path and configured to circulate along the annular path to be able to convey an absorbent article and a path switching mechanism configured to switch a conveyance path specified by the conveying belt between a path along which the absorbent article is transferrable from an upstream conveying mechanism to a downstream conveying mechanism and a path along which the absorbent article is guided along a sampling path from the upstream conveying mechanism.

A sheet discharge apparatus includes a discharge unit configured to discharge a sheet in a discharge direction, a stacking surface configured to stack the sheet discharged by the discharge unit, and a wall including a plurality of hole portions and an abutting part, wherein the plurality of hole portions includes a first hole portion disposed across an extension line along the stacking surface when viewed in a width direction, the first hole portion including a first edge portion and a second edge portion, the first edge portion being positioned on a side of the stacking surface, and wherein, in the vertical direction, an upper end of the first edge portion of the first hole portion is positioned above the extension line, and a lower end of the first edge portion of the first hole portion is positioned below the extension line.

A sheet stacking tray that includes a single pneumatic baffle which uses the pressure differential caused by the flow of air across a horizontal planar surface of the pneumatic baffle to hold the lead edge of sheets driven by an input nip into the sheet stacking tray above a stack especially for longer and lighter weight sheets as they are driven by the input nip to a registration wall.

An apparatus for picking a product, including: at least one vacuum cup including at least one axis passing through the at least one vacuum cup; and at least one damping device surrounding at least a portion of the at least one vacuum cup in a radial direction orthogonal to the at least one axis. The at least one vacuum cup is arranged to create negative pressure and adhere, with the negative pressure, the at least one sheet of material to the at least one vacuum cup. The at least one damping device is arranged to contact the at least one sheet of material to limit displacement of the at least one sheet of material with respect to the at least one vacuum cup.

A sheet stacking device includes a vacuum system that delivers an individual sheet toward a binder element, a sheet deflector element that presses an end of the individual sheet onto the binder element, and a sheet kick-down element that presses the individual sheet away from the vacuum system.
