  • Patent number: 9017241
    Abstract: Aspects of the present disclosure relate to tucking opposing side panels into a chassis of a diaper pant. The apparatuses and methods may utilize one or more conveyors that advance the chassis along a machine direction. Each conveyor may have a vacuum zone that applies a vacuum force to hold the chassis. The chassis may be positioned between a first conveyor having a first vacuum zone and a second conveyor having a second vacuum zone. The conveyors may apply opposing vacuum forces to hold the first waist region apart from the second waist region while the chassis advances in the machine direction toward a tucking device. The vacuum forces are then removed from the waist regions as the tucking device pushes the side panels toward each other. Pushing the side panels toward each other causes the inner surfaces of the waist regions to simultaneously move toward each other.

The garment is positioned between an upper vacuum conveyor and a lower vacuum conveyor. Opposing vacuum zones from the upper and lower conveyors hold a front region of the garment away from a back region of the garment. While the garment is in the opened, or pulled apart, position, the side panels are pushed between the front and back regions toward one another.

  • Patent number: 6679034
    Abstract: A vertical stand-up pouch, flat bottom bag, or flexible package, and method for manufacturing same, constructed with a quick change module modification to existing vertical form and fill packaging machines. The invention involves producing a vertical stand-up pouch or flat bottom bag from a single sheet of packaging film by creating one or two vertical creases along the packaging film tube prior to forming a transverse seal on the tube. Such creases are formed using fixed or stationary modifications to prior art vertical form, fill, and seal machines comprising, in part, a quick change module that easily installs on the base of a forming tube.

  • Patent number: 6673003
    Abstract: An elongate rail for an equal path folder that has a hollow tube having a a longitudinal axis and a vacuum applied thereto, and a first and second substantially planar surfaces parallel to the longitudinal axis and forming a folding edge therebetween. The hollow tube has at least one opening positioned angularly away from both the first and the second surfaces. The vacuum causes a negative pressure to be applied to the opening so that a web substrate passing over the first and second surfaces has at least a portion of the vacuum applied to a face of the web substrate when the web substrate is proximate to at least one of the first and second surfaces thereby substantially reducing particulate matter build-up on the folding equipment and substantially reducing the undesirabie particulate matter left on the out-going web product.

  • Patent number: 6612974
    Abstract: An adjustable card folding station includes an adjustable vacuum bed and moveable gates. The vacuum bed includes at least two sections that are movable with respect to each other to accommodate cards of different widths. Each section of the vacuum bed further includes multiple suction cups, each of which is individually connected to a vacuum supply. The vacuum supply independently controls each suction cup so that vacuum can be applied to selected or all suction cups such that cards of different lengths can be accommodated. The movable gates are pivotally mounted with respect to the vacuum bed and operated by motors to pivot 180 degrees from open to closed positions to fold the cards.

  • Patent number: 6514187
    Abstract: A method of folding pants is suitable for use with discrete articles including mechanical fastening components and suitable for the manufacture of prefastened and refastenable pants. The discrete articles define leading and trailing halves with opposed side panels. The leading side panels can be maintained separate from the trailing side panels during folding and until the discrete articles are downstream of a folding nip.

  • Patent number: 5915319
    Abstract: A hemming and seaming machine (5) having a hemming conveyor (16) on which a workpiece is moved along a path of travel toward and through a hemming station which sews a hem in the workpiece is disclosed. The hemmed workpiece is then moved downstream to a folding station (25) where a spaced series of first air jets (61) selectively emit streams of air between a folding plate (26) and clamping plate (55) to create a vacuum therebetween to draw the leading edge of the workpiece off of the hemming conveyor and between the folding plate and the clamping plate. The leading edge of the workpiece is held between the clamping and folding plates while the workpiece continues to move along the path of travel. After a predetermined period of time has elapsed from the detection of the leading edge of the workpiece, or in response to the detection of the trailing edge of the workpiece, the leading edge of the workpiece is released from between the folding and clamping plates.

    Abstract: A hemming and seaming machine is disclosed, the machine having a hemming conveyor on which a workpiece is moved along a first leg of a U-shaped path of travel toward and through a hemming station which sews a hem in the workpiece. Thereafter, the hemmed workpiece is then moved downstream toward a folding station where a spaced series of first air jets selectively emit a stream of air in a direction opposite the direction of the path of travel between a folding plate and a clamping plate to create a vacuum therebetween to draw the leading edge of the workpiece upward and between the folding plate and the clamping plate. Thereafter, the leading edge of the workpiece is held between the clamping and folding plates while a second series of air jets positioned upstream of the folding plate selectively blows a stream of air underneath the folding plate and against at least a portion the workpiece as it moves along the path of travel.
