  • Patent number: 5904277
    Abstract: The machine of the present invention makes single or double transverse folds in segments cut from a continuous web. It includes feeder and cutter mechanisms to transfer segments to the surface of a central folding drum. A controlled vacuum source selectively applies vacuum to leading and trailing portions of the segments during advancement and folding. Segment portions are held by vacuum applied through ports arranged in pre-selected patterns that include transverse fold lines. An air blast directed through apertures in the drum surface urges leading portions of the segment upward to project radially before fold completion by contact with a stationary plate. Air blast can be used alone or in combination with mechanical means to complete the folds. Selective placement and operation of vacuumized ports and air blast apertures in combination with mechanical means are used to achieve multiple transverse folds.
