    • An apparatus and method for winding a sheet of aligned parallel yarns onto a beam is described. The beam winder utilizes a circularly arced yarn spool rack that feeds each yarn to an alignment comb through associated guide tubes. The distance between each spool of yarn and the alignment comb is substantially the same for all spools of yarn, thereby equalizing the force necessary to pull them to the comb. Next, the aligned sheet of material is preshrunk using heated rollers and wound onto a beam. Multiple speed controlled stepper motors are utilized to maintain a constant low level of tension in the sheet during the shrinking process. After shrinkage, the tension level of the yarn sheet is increased as it is wrapped onto the beam. A turntable that supports two or more beams is provided to facilitate the rapid switching of beams once one beam has become full.
    • 描述了将对齐的平行纱线卷绕到梁上的装置和方法。 卷绕机使用圆形的纱线卷轴架,其通过相关联的导管将每根纱线馈送到对准梳。 纱线的每个卷轴和对准梳之间的距离对于所有的纱线卷轴基本上相同,从而使将其拉到梳子所需的力相等。 接下来,对准的材料片材使用加热辊预先挤压并缠绕在梁上。 在收缩过程中,使用多速度控制的步进电机来保持片材中持续的低水平张力。 收缩后,纱线片的张力水平随包裹在梁上而增加。 提供支撑两个或更多个光束的转台,以便一旦一束光束变满,就有助于光束的快速切换。

    • An apparatus for applying weft yarns in a cross direction to warp yarns assembled on a beam in parallel aligned relationship and having an adhesive scrim thereon includes a supply roll of the warp yarns on such a beam which are fed downstream of the apparatus by first laying the warp yarns onto a transfer belt to reduce the tension in the yarns and controlling them for application of the weft yarns. A transfer belt and warp yarns are first folded between folding bars into a cylindrical configuration where they are formed around the perimeter of an elongated mandrel having a heated section at its upstream end and a cooling section at its downstream end. The adhesive scrim is softened as the warp yarns pass over the heated section of the mandrel and shortly thereafter, weft yarns are wrapped around the warp yarns and the supporting transfer belt within a rotating tube having a plurality of longitudinally and circumferentially spaced spools of weft yarn disposed on its outer surface. The yarns are fed upstream from the spool along the rotating tube on which they are mounted and pass through a tensioning apparatus to unify the tension in the various yarns running along the tube. The uniformly tensioned weft yarns pass through individual equally circumferentially spaced nozzles around the circumference of the rotating tube where the yarns are deposited onto a laydown ring having a sloped surface that urges the yarns downwardly so they are deposited around the cylindrical surface of the mandrel and onto the adhesive scrim on the outer surface of the warp yarns. After having been deposited on the warp yarns, the transfer belt moves the fabric having warp and weft yarns across the cooling section of the mandrel where the adhesive is set. Subsequently, a cutter severs the weft yarns in a longitudinal line along the bottom edge of the cylindrical fabric and a pair of unfolding rods move the transfer belt and fabric carried thereby from the cylindrical form in which the fabric was created to a flat sheet form. After flattened into elongated sheet form, the fabric is separated from the transfer belt and accumulated on a take up drum.
