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.

Abstract: An apparatus and method for applying a foamed composition to a traveling substrate that has a tendency to be dimensionally unstable. A pair of closely spaced driven guide rollers guides a traveling substrate with sufficient roller engagement and controlled tension to minimize dimensional distortion. A foam applicator with a substrate engaging foam dispensing nozzle face is positioned within the space between the rollers to deflect the substrate inwardly between the rollers. The face extends in close proximity to the rollers to minimize the free extent of travel of the substrate between the rollers and the nozzle face. Two pairs of guide rollers and two nozzles may be arranged for applying foamed composition to the opposite sides of the traveling substrate.

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.

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.

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.
