  • Publication number: 20140304923
    Abstract: A washer that washes a continuous piece of tubular knitted fabric material. The washer includes a frame, a set of rollers, an air nozzle rack, and a controller. The frame rests on a support surface. The set of rollers are rotatably attached within the frame and guide the material through a washing liquid to wash the material. The air nozzle rack is replaceably attached to within the frame and blows air onto the material to cause ballooning of the material to maximize exposure of a total surface area of the material to the washing liquid. The controller is operatively connected to the set of rollers and minimizes and keeps constant the tension of the material as the material passes through the washing liquid under an influence of the air nozzle rack to thereby provide a more effective wash of the material.

  • Publication number: 20040211229
    Abstract: Disclosed is a wet hand towel supply apparatus characterized in that a winding-up initiating protrusion is formed on a surface of the hand towel guide member facing to the hand towel fabricating passage exclusively in a portion thereof facing to an end portion of the front belt portion in said winding roller side. As a result, the starting of the winding-up operation of the sheet material can be delayed as compared to the case of a conventional apparatus. Consequently, a cutting position of the sheet material can be set always in a location of a perforated line or a location shifted therefrom a little toward the leading edge side of the sheet material. Owing to this, the sheet material can be cut smoothly in the exact cutting position into pieces each having a correct length for a single piece of hand towel.

  • Patent number: 4338876
    Abstract: The application of liquid to a moving fabric is effected by delivering same to a rotatable spinning disc which centrifugally impels the liquid against the fabric. This action overcomes surface tension causing the liquid droplets to break up into a fine mist so that a large area of fabric is wetted with an amount of liquid which is substantially less than the fabric weight. Also, the velocity imparted to the liquid droplets in mist forms enhances absorption of the liquid by the fabric.

  • Patent number: 4292918
    Abstract: In a preferred embodiment of the invention, a manifold in the form of a pipe having a closed end is utilized to supply a finishing agent to orifices arranged at spaced intervals along the pipe. A foam material surrounds the manifold to receive the finishing agent and to apply it in a thin film to the curved surface of an element comprising a longitudinal section of a cylinder. The film is retained on the curved surface by surface tension as it moves under the force of gravity to a longitudinal edge of the cylindrical section. A web of fabric is tensioned against the section edge as the fabric moves past the cylindrical section. The direction of fabric movement is such that the film of finishing agent is applied to the fabric immediately ahead of the line of contact between the fabric and the section edge.

  • Patent number: 4051699
    Abstract: Apparatus for mercerization of cellulosic fabrics with liquid ammonia. Denim fabrics and the like, especially those made from open-end spun yarn, have liquid ammonia for mercerization applied thereto by a metering roller while tensioned. The metering roller has a number of deep engravings formed in the periphery thereof, which may be in the form of a truncated cone or a tetrahedron. Pile or ribbed fabrics are treated by application of liquid ammonia with a metering roller to the back of the fabric, while tension is maintained by relatively gentle apparatus, such as a pinned drive cylinder. When fabric direction is changed, soft rollers engage the fabric face to change the direction, and the fabric face is brushed with rotary driven brushes of Nomex or the like. Final ammonia removal from the fabric is facilitated by passing the fabric over a large cylinder with a perforated surface, steam transfer occurring across the fabric in the steam chamber.
