  • Patent number: 4203584
    Abstract: First and second bundles of interfolded webs are formed. The uppermost web half of the first bundle is interfolded with the lowermost web half of the second bundle at a merging station. These web halves travel along parallel and inclined fold surfaces and become interfolded upon being discharged therefrom. To unfold the uppermost web half for travel along its associated fold surface a freely rotatable roller is positioned upstream of such fold surface. The roller is arranged to be contacted and frictionally driven by the uppermost web half. The roller is oriented toward the fold line of the uppermost web half so that upon driving the roller, the uppermost web half becomes unfolded. To promote unfolding of the lowermost web half of the second bundle a stationary elongate band is disposed between the lowermost web half and the remaining web halves of the second bundle.

  • Patent number: 4181552
    Abstract: A machine and a method are disclosed for forming pleated and wound electrical capacitors having a metallized dielectric which is metallized on both sides to form electrodes thereon. The metallized dielectric material is fed from supply rollers and it is pulled tightly over one or more rotatable discs so that it is locked firmly onto the periphery thereof. In one embodiment, three rotatable discs are employed and the center disc projects beyond the other two discs which are aligned at acute angles with respect to the center disc. After the dielectric material leaves these discs, it passes through a low pressure air stream which smooths out the wrinkles in the material. It is then fed under tension around a substantial portion of the periphery of a relatively large winding wheel.

  • Patent number: 4061325
    Abstract: A machine for interfolding webs of material which includes a plurality of interfolding mechanisms for interfolding webs into a plurality of elongate bundles. Drive mechanism is provided for advancing first and second ones of the bundles in taut condition, with the second bundle being disposed beneath the first bundle. First and second fold plates are disposed vertically intermediate the first and second bundles. These plates are inclined relative to a vertical plane and lie in generally mutually parallel planes. The first fold plate is arranged to guide the top web of the first bundle in an upwardly unfolded condition during advancement of the first bundle. The second fold plate is arranged to guide the bottom web of the second bundle in a downwardly unfolded condition during advancement of the second bundle.

  • Patent number: 3980289
    Abstract: An apparatus for simultaneously folding and interfolding a multiplicity of webs of flexible material such as facial tissue paper in the machine direction to form an endless bundle of interfolded webs which endless bundle can be cut into discrete bundles and packaged in pop-up dispensing containers. The apparatus comprises a fan-shape, horizontally disposed folding table comprising a set of tapered elongate guides having inverted V-shape cross sections. The elongate guides are disposed in side-by-side relation and thereby form tapered V-shape troughs therebetween. The webs are directed in convergent relation onto the radially outwardly disposed edge of the fan-shape table in partially overlapped relation and are drawn radially inwardly thereacross and thence about a turning guide whereupon the folds of the webs are alternately V-folded upwardly in said troughs and downwardly about the ridges of the elongate guides so that an edge fold of each web is disposed intermediate two folds of an adjacent web.
