Definitions

  • the present invention relates to a method and apparatus for removing floating pile yarn ends from a pile fabric, such as a multi-colored carpet weave.
  • Carpet weaves which have multi-colored pile yarns located between the top ply and the bottom ply of the fabric, and forming tufts projecting from a top surface after the fabric has been split between the two plies.
  • the pile warp yarns which do not participate in the production of the pattern, and which are usually referred to as stuffers or dead warps, float between the tufts in the top ply, and the bottom ply and are cut with the same when the fabric is split between the two plies.
  • Another object of the invention is to provide an apparatus by which the dead pile yarn ends of a pile fabric are efficiently raised above the top surface of the pile and cut off.
  • Another object of the invention is to provide a method and apparatus for removing dead pile yarn ends in a continuous and inexpensive operation from a pile fabric, such as a carpet.
  • Another object of the invention is to provide means for individually raising dead pile yarn ends above the top surface of the fabric so that the raised ends can be easily and efiiciently removed.
  • the present invention relates to a method of removing floating yarn ends.
  • the method comprises the steps of placing a pointed tool, such as a spike, in a position projecting in a plane extending in the weft direction of the fabric transversely to the fabric through the tufts into the proximity of the bottom of the fabric; moving the fabric and the tool relative to each other in the weft direction, and preferably also in the warp direction of the fabric so that the free ends of the floating yarns are raised above the top surface of the pile of the fabric; and cutting off or otherwise removing the raised yarn ends.
  • a pointed tool such as a spike
  • the fabric is attached to a rotating cylinder with the weft extending in circumferential direction of the cylinder, so that the rotating cylinder moves the fabric in the weft direction.
  • the pointed tool, or spike is simultaneously moved in the warp direction of the fabric so that the free ends of the floating yarns are successively raised above the top surface of the pile where they are cut off.
  • An apparatus includes first support means, preferably having a cylindrical surface for supporting the fabric; second support means for supporting a pointed tool projecting through the tufts of the fabric; and cutting means disposed following the pointed tool in the direction of relative movement between the first and second support means in the weft direction.
  • the pointed tool is movable in the warp direction so that the entire area of the fabric is cleared of floating pile yarn ends in a continuous operation.
  • FIG. 1 is a fragmentary cross sectional view illustrating one embodiment of the invention.
  • FIG. 2 is a front elevation, partially in axial section, of the embodiment of FIG. 1;
  • FIG. 3 is a longitudinal sectional view taken in the warp direction of a two-ply fabric.
  • a woven pile fabric 2 is placed on the cylindrical surface of a rotary support 1 so that the weft-yarns extend in circumferential direction,
  • support drum 1 has an axial length at least equal to the length of the pile fabric, and a circumferential extension greater than the width of the fabric.
  • the bottom ply of the pile fabric lies on the cylindrical surface of the support drum 1, and the pile faces outward.
  • the dead pile yarn ends are also warp yarns, and extend in axial direction of the support drum 1.
  • a first ply A and a second ply B are woven on a loom and after the weaving has been completed, the two ply fabric is cut along the line C so that the fabric is split into two halves, each of which has a base and tufts projecting from the base.
  • Each ply comprises base yarn D, crossing warp yarns E, transverse weft yarns F, and differently colored pile yarns G G G
  • the pile yarns G G G G are interlaced into the upper base fabric U and into the lower base fabric L, and then float for a considerable distance until again interlaced into the upper and lower base fabrics.
  • each of the two pile fabrics is treated for the purpose of first raising the portions G G 6;, of the pile yarns to a position projecting above the top surface of the tufts, as shown at 24 .in FIG. 1.
  • the tufts formed by cutting along the plane C have the proper length and form the pile surface, but the floating yarn portions, which extend partly in the warp direction, must be raised to a position parallel to the other portions of the pile yarns forming the tufts, and in this position, they project beyond the top surface of the pile as shown at 24 in FIG. 1. Thereupon, the projecting ends 24 are cut off by the cutter 5.
  • FIGS. 1 and 2 show only one base fabric 23 and a pile 21, and do not show the other base fabric and the pile of the same, since the double ply carpet weave is split before performing the operations according to the present invention, so that the operations are carried out only with one-half of the double ply carpet weave shown in FIG. 3.
  • the selvedges 22 of the base 23 of the fabric are woven somewhat wider than is usual, and attached by a suitable holding means, such as pin boards 12 to the walls of a recess in the drum surface.
  • a shaft 13 is mounted in bearings 14, and is driven by a motor, not shown, to rotate support drum 1 in the direction of the arrow a.
  • the pointed tool shown to be a spike 3, is mounted on a support 4 which is movable in axial direction of support drum 1 in the direction of the arrow b, and along a bed 41 corresponding to the tool support of a lathe.
  • the pointed spike 3 is adjusted in radial direction of the support drum 1 so that .its point projects through the tufts into the proximity of the inner bottom ply 23 of the fabric as shown in FIGS. 1 and 2, and thus engages the loose pile yarn ends which are located between the tufts of the fabric.
  • the pointed tool 3 extends at an acute angle to the surface of the support drum 1 and to the surface of the fabric so that the loose pile yarn ends slide upon the pointed tool and are raised above the top surface of the pile, assuming a radially projecting position 24.
  • the rate of feed of support 4 and tool 3 across the rotating fabric 2 in axial direction of the drum is exactly determined so that the tool will consecutively engage and raise the loose ends of the floating pile yarns according to the rate of feed of tool 3 in axial direction of support drum 1 and in the warp direction of the fabric.
  • the tool 3 is located in a plane extending in the weft direction of the fabric, and perpendicularly to the axis of the drum.
  • a cutting means in the form of a rotary shearing cylinder 5 of selected axial width is located substantially in the same plane and follows tool 3 in the direction of rotation of support drum 1. Shearing cylinder 5 is moved parallel to the axis of drum 1 in the direction of the arrow b at the same speed as support 4 and tool 3. Consequently, relatively short lengths of pile yarn ends are lifted out of the pile during each rotation of support drum -1, and are cut off during the same rotation by cutting means 5.
  • the method of removing floating yarn ends located between the tufts of a pile fabric of predetermined dimensions comprising the steps of engaging the free ends of floating yarns with a pointed tool projecting through the tufts into the proximity of the base of the pile fabric; causing relative rotary movement of said pile fabric and said tool repeatedly substantially in the weft direction of said pile fabric so that the free ends of floating yarns between said tufts in the path of said tool are raised by said tool above the top surface of said tufts; causing relative axial movement of said pile fabric and said tool in the direction of the axis of said relative rotary movement and in the warp direction of the pile fabric during said repeated movements in the weft direction so that the entire pile of said pile fabric is run through by said tool and all free ends of the floating yarns are raised above the top surface of the pile; and cutting off said free ends of said floating yarns at the top surface of said pile.
  • the method of removing floating yarn ends located between the tufts of a pile fabric of predetermined dimensions comprising the steps of mounting the base of the pile fabric on a cylindrical support so that the warp yarns of the base extend in axial direction, the weft yarns extend in circumferential direction, and the tufts project radially outward; engaging the free ends of floating yarns with a pointed tool projecting through said tufts into the proximity of the top surface of the base of said pile fabric; rotating said support so that the free ends of floating yarns located between said tufts are engaged.
