    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: 5954006
    Abstract: The apparatus of the invention is applied to a case of folding, for example, the sleeve cloth of short-sleeved T-shirt in half while conveying. A holding device grips the leading end of the cloth conveyed on a conveying surface of narrow conveyor belts, lifts the gripped leading end of the cloth from the conveying surface, and holds it above the conveying surface temporarily. A cloth stopping device stops conveying of the front side portion of the conveyed cloth on the conveying surface at a position of an upstream side in the conveying direction from the holding device. When cloths are put on the conveying surface by overlaying mutually in part, a space is formed between the preceding cloth and succeeding cloth by the cloth stopping device, so that the leading end of the cloth is gripped and lifted by the holding device.

  • Patent number: 5782737
    Abstract: A vehicle safety airbag is folded to an annular compact accordion-like configuration for placement around a conventional bag inflator. The bag folding operation involves axially stretching the bag, restraining localized areas of the stretched bag against radial expansion, and axially compressing the bag while moving the restraining devices together, such that annular accordion-like folds are formed in the bag.

  • Patent number: 5779614
    Abstract: An arrangement is provided for the automatic folding of toy balloons. A series of folding plates are provided along a path of travel and a vacuum conveyor provides traction force for the balloon as it slides across the folding plates. The folding plates interfere with the path of travel of the balloon causing the balloon to fold side-to-side. Tucking blades fold the balloon lengthwise to complete the folding operation.

  • Patent number: 5730695
    Abstract: An apparatus for stacking zig-zag interfolded articles such as towels (3) cludes two carrier forks (22, 23) extending toward each other from opposite sides and forming a two-piece stacking table (8) onto which the folded towels are stacked. The apparatus further includes a pair of separating and auxiliary carrying forks (11, 12) that reach into the forming stack from opposite sides. In a method of stacking interfolded towels, the towels are stacked on the two piece stacking table (8) so that the folded edge of consecutive towels alternately faces to the right and to the left. The carrier forks (22, 23) of the two-part stacking table (8) reach under and support the bottom of the stack (2) from opposite sides and lower the stack onto a conveyor belt (26). Meanwhile, the separating and carrying forks (11, 12) reach under and support the bottom of a new stack being formed, from opposite sides.

  • Patent number: 5729954
    Abstract: A flap opening apparatus wherein envelopes are sequentially conveyed past a jet nozzle, which delivers timed blasts of air to open the flaps of each envelope. A computer controller tracks the position of the envelopes by a shaft encoder, and activates the jet nozzle when each envelope is correctly positioned. The opened flaps of the envelopes are held in an open position by a plate so that mail materials may be inserted into the envelopes.

  • Patent number: RE35265
    Abstract: An automated system is disclosed for folding vehicle air bags so that a small folded-bag profile and a desirable bag deployment pattern results. A machine having numerous moveable arms is controlled by a controller. An edge folding assembly (EFA) of the machine has five arms, including a center arm, two outer blades, and two outwardly facing U-channel forks, which reside between respective outer blades and the center arm. The EFA moves forward so that all of its five arms engage an unfolded air bag. The forks then raise upward to a level at which the outer blades are aligned with a gap between tines in the forks. The outer blades mesh with this gap causing two pleats to be formed in the edge of the bag. Pleat clamps then move inwardly sideways to engage the two pleats and form a third pleat. Then, the EFA is removed from the bag. The pleat clamps clamp top and bottom sections of the bag together while tightly gripping the pleats.
