  • Patent number: 4894894
    Abstract: A continuous, high speed (greater than 800 meters per minute) process and apparatus enable the production of a multifilament carpet yarn having a degree of filament intermixture high enough so that a standard deviation of less than 6.0 results upon conducting a Standard Yarn Streak Potential Test, as described herein. The apparatus and process allow the production of a multicolored carpet yarn which exhibits a reduced tendency to streak and an increased retention of tip definition.

  • Patent number: 4884325
    Abstract: The process herein described provides the weaving of a manufactured product consisting of an upper fabric (2) made of cotton or any other suitable material and a lower fabric (3) with weft yarns (3a) made of wool and warp yarns (3b) interlaced with the weft yarns (2a) of the upper fabric (2). The weaving operation is followed by a printing step carried out on the upper fabric (2) of the manufactured product and by one or more teaseling steps on the lower fabric (3). Subsequent to each teaseling step there is a dimensional stabilization step of the manufactured product accomplished by a combined action consisting in moistening, heating and tensioning the product, the tensioning lasting until the end of the moistening and heating steps. A napping operation is also carried out together with the last teaseling step. By said process a blanket is obtained which comprises an upper fabric (2) with weft yarns (2a) interlaced with the warp yarns (3b) of a lower fabric (3).

  • Patent number: 4882819
    Abstract: A method for compressive lengthwise shrinking of tubular knitted fabrics and other materials, particularly in a single stage. Feeding and retarding rollers are separated from each other by a distance significantly greater than the thickness of the fabric. Zone-forming blades are projected between the rollers from opposite sides and form between them a confinement zone which extends at a large angle from the feeding roller to the retarding roller. Fabric is guided to the zone under low contact pressure by the feeding roller and is conveyed away from the zone under similarly low contact pressure by the retarding roller. At the entrance to the zone, the fabric is decelerated and compacted lengthwise without burnishing or abrasion and without crimping. Tubular and open width knitted fabrics can be compressively preshrunk in large amounts, up to 25% and more, in a single stage. Significant savings and other benefits are realized.

  • Patent number: 4879788
    Abstract: This invention provides a drawing machine for pinching and stretching a film-like material of the type having rails installed extending from an inlet section to the outlet section and returning in the opposite direction from the outlet section back to the inlet section of the drawing machine. There is a clip propelling unit moving on the rails for pinching and stretching the film-like material, and elements for generating mutually repelling magnetic fields between the rails and clips, whereby the clips are movable in the non-contact state while floating from the rail guide surfaces. Thus, no foreign substances are generated, cleanliness of products is enhanced, no noise is generated, the work environment is improved, energy is saved, and highspeed operation is attained.

  • Patent number: 4878278
    Abstract: An apparatus and method for papermaking fabrics (W) with a machine direction fiber batt (24) is disclosed. A carding machine (B, B') is arranged with its carding cylinder (39) parallel to the axis of rotation (22) of carriage rollers (20) about which a base fabric (16) travels in a machine direction. A carded batt (24) with fibers (36) oriented in the machine direction is fed directly in the machine direction onto base fabric (16). An auxiliary needling unit (A) including an auxiliary needling module (44) lightly tacks machine direction batt (24) to base fabric (16) across its width. For this purpose, carding machine (B) and base fabric (16) move relative to one another in a direction transverse to the machine direction. In one embodiment, card (B) moves transversely in synchronization with auxiliary needling unit (A) while carriage (18) carrying the base fabric is stationary.

  • Patent number: 4878280
    Abstract: This invention relates to an apparatus and a process involving fluid jet devices for intermingling filaments of a continuous filament yarn or yarns, including combining a plurality of yarns to produce a larger coherent yarn. More particularly, the invention relates to fluid jets having a passageway through which yarn moves, where the yarn is positioned and maintained along one wall as it passes through the passageway and where the fluid-directing orifice in the jet is offset with respect to the passageway in the direction of the wall. The apparatus and the process are useful in producing heather yarns with superior yarn blending and along-end uniformity.

  • Patent number: 4870727
    Abstract: The apparatus detects corduroy cutter needles coming out of the weft yarn loop channels which are being cut open by the needles, by means of a laser beam scanning about 10 to 20 times a second, transversely across the region where the parallel needles are working. The scanning laser beam creates a diffused light pattern having the general form of a transversely oriented geometric prism, e.g. a cylinder; and a plurality of detector devices determines any variation in the light distribution, as to time and lateral distance, in this scattered or diffused light pattern. A logic circuit carries out and displays the results of the scanning and detecting, and stops the corduroy cutting machine when an emerged needle is detected.
