  • Patent number: 10407822
    Abstract: In laundry processing, a conveyor rotates a textile article in a first stage. The article is held while part of the article rests on the conveyor. By conveying while held, the textile article rotates, positioning an edge of the article. In a second stage, the conveyor conveys the article to a clamp. This clamp holds the article while the conveyor reverses direction and a blower attempts to flatten the article if folded. The textile article rotates, positioning the edge of the article to be more parallel with the direction of conveyance. In a third stage, the article is dragged by the edge over a gap where gravity and blowing attempt to flatten the article. In a fourth stage, the flattened article is positioned over a stack. A blower directs air at a center of the article to blow out the corners and assist in maintaining position.

  • Patent number: 7039990
    Abstract: Apparatus and methods for stretching one or more zones of a web are disclosed. Webs including stretched or activated zones are also disclosed. Each of the zones in the web is stretched in the cross-web direction, i.e., the direction transverse to the down-web direction. The stretching it can be performed continuously as the web is advancing through the apparatus in the down-web direction. The stretching can occur in the absence of physical contact with the stretched zone of the web. Strain induced on the stretched zones can be introduced gradually over a stretch distance. The strain may increase at a linear rate. The stretching methods and apparatus may be used to activate an elastic zone or zones within a web.

  • Patent number: 6311377
    Abstract: A process and apparatus for spreading fibers in a fibrous tow provides a fiber spreader for spreading a tow of fibers moving in a machine direction having a plurality of spaced pins, where the spacing between the pins is variable relative to the machine direction, and the position of the pins is variable relative to the machine direction. Variation of the spacing and position of the pins during motion of the pins contact with a tow moving generally in the machine direction provides a spread tow of lower, more uniform areal weight for further use in product applications. Variation in pin spacing and fiber spreading results from rotation of at least one pin relative to another after the pins are inserted into a tow. Alternate techniques for fiber spreading and additional features for stress relief of fibers during the fiber spreading operation are disclosed.

  • Patent number: 5537726
    Abstract: A film or web stretcher particularly for thermoplastic film has a plurality of stretching cylinders, at least one or more of which cooperate with a press-on roller particularly at the inlet and/or outlet of the stretcher. A mounting arm (6) at each end of the stretcher cylinder permits the mounting of the press-on roller in such a way that the latter can be tilted through a limited angular range about the rotational axis of the stretching cylinder by a first drive. A second drive, such as a piston cylinder device adjusts the press-on roller relative to the stretching cylinder to thereby apply a press-on force. The first drive may, for example, be accomplished by a manually driven device for positioning the press-on roller and its cooperating components in any one of two end positions and in any position between the two end positions. The press-on roller may be directly mounted to the mounting arms (6) or through support brackets (9) to the arms (6).

  • Patent number: 5455992
    Abstract: A widening device for increasing the width of a moving web of material comprises a rotatable profiled roller, the outer surface of which defines a plurality of radial projections and recesses distributed along the length of the roller and first and second co-operating rollers rotatable at the same speed as the profiled roller. The first and second co-operating rollers define projections and recesses complementary to those of profiled roller and define first and second treatment nips which serve to increase the width of a web of material passed therethrough. The projections on the co-operating roller defining the second treatment nip extend more deeply into the recesses of the profiled roller than do the projections on the co-operating roller which defines the first treatment nip so that the web of material is stretched gradually over two stages with the stretching effect being uniform across the entire width of the web.

A pinch roller is mounted at the input. A plurality of rollers are circumferentially disposed around the pinch roller and the axis of rotation of those rollers is parallel to the center line of the tubular web. A turning bar is disposed in the interior of the spindle and turns the flattened web exiting the pinch rollers 90 degrees and feeds the horizontal web to a first roller of the plurality of rollers disposed at the periphery of the spindle. The traveling web always passes over this first roller. By rotating the spindle in an oscillatory manner about the center axis of the tubular web, the horizontally traveling, flat web is wound and unwound around the outer periphery of the spindle and is fed to a fixed idler roller.

  • Patent number: 4035878
    Abstract: This invention provides an apparatus for removing wrinkles in a thin flexible moving web such as paper or textiles. The web is passed over a bar curved to effect a shear force on the web and/or a tensile force on the web in a direction perpendicular to the direction of movement of the web. The bar is oscillated resonantly or nonresonantly with one component of the oscillation being in a direction normal to the web surface so that its intermittent contact with the web causes any wrinkles therein to collapse. Gas, under super-atmospheric pressure can be passed through ports in the bar surface and into contact with the web to assist in collapsing wrinkles.
