  • Patent number: 7677560
    Abstract: An apparatus for deflecting sheet material from a first transport direction to a second transport direction while maintaining the orientation of the sheet material comprises a deflecting area (5) with a sheet-material supply zone (5a) and a sheet-material removal zone (5b), as well as at least one slider (11) with slider elements (12), which engages on the trailing edge of the sheet material to be deflected. By moving the slider from the sheet-material supply zone to the sheet-material removal zone around a rotation axis (13) the sheet material is deflected by the desired deflection angle. The sheet-material transport path preferably has two steps and the rotation axis (13) of the sliders (11) is preferably arranged in such a fashion that the slider elements (12) substantially only engage with the sheet-material transport path in the deflecting area (5) and emerge from the sheet-material transport path both upstream of the sheet-material supply zone (5a) and downstream of the sheet-material removal zone (5b).

    Abstract: A conveying method permits conveying of printed products, particularly in the form of a scale flow, with a constant or variable speed over conveying distances of random length, which can also contain rising or falling portions in the conveying direction, as well as curves. The method is based on the fact that each individual printed product or small group of printed products is conveyed by a conveying a element over a step length (S) which is small compared with the entire conveying distance and is then taken over by the next conveying element, while the first conveying element is moved back to its starting point. This process is repeated in a time cycle with the cycle length (T). The corresponding apparatus comprises a fixed support and a plurality of conveying elements, which are driven in a timed manner. A conveying distance or section can comprise a plurality of conveying modules, no transfer units being required between the individual modules.

The apparatus includes a rotatable ply gripping wheel, cooperating with a ply holding shoe. By rotating the wheel in contact with the ply, while restraining an adjacent area, the ply is buckled into a wave, nipped and then picked off of the stack. The gripping wheel and pressing shoe maintain a predetermined geometric relation, while being capable of independent yieldable contact with an uneven ply stack. The gripping wheel and holding shoe are operable in conjunction with an insertable flat plate, which is effective to progressively free the remainder of the ply. Thereafter, the flat plate is utilized to transport the freed ply to a desired destination, while the picking unit independently returns to the ply stack to commence its engagement with the next subsequent ply.

  • Patent number: RE30084
    Abstract: A method and apparatus for separating a single ply of limp material, such as fabric from a stack of such plies, and transporting the separated ply to a predetermined destination. The apparatus includes a rotatable ply gripping wheel, cooperating with a ply holding shoe. By rotating the wheel in contact with the ply, while restraining an adjacent area, the ply is buckled into a wave, nipped and then picked off of the stack. The gripping wheel and pressing shoe maintain a predetermined geometric relation, while being capable of independent yieldable contact with an uneven ply stack. The gripping wheel and holding shoe are operable in conjunction with an insertable flat plate, which is effective to progressively free the remainder of the ply. Thereafter, the flat plate is utilized to transport the freed ply to a desired destination, while the picking unit independently returns to the ply stack to commence its engagement with the next subsequent ply.
