Definitions

  • FIGS. 1-5 represent schematically the basic concept of the invention
  • FIG. 6 is a partial view of the yarn collector and distributor cylinder
  • FIGS. 7 and 8 are schematic representations of two .forins of the individual discs used in the yarn collector
  • FIG. 18 represents a modification of the invention in each of the discs 12.
  • the discs are secured together in any suitable manner to provide an elongated right circular cylinder which is mounted on a horizontal axis to supply bits of yarn 16 and 18 in a substantially perpendicular direction into the adhesive surface 30.
  • the adhesive surface 30 can be applied to a backing material or, depending on the adhesive, can be applied directly to the conveying surface 32.
  • the particular adhesive could be liquid at the point of yarn insertion requiring heat or time to become a permanent bonding vehicle or could be a hot melt requiring only cooling.
  • the adhesive surface 30 can be planar at the point of yarn insertion as shown in FIGS. 14 and 16 or can be curved at the point of insertion as shown in FIGS. 1-6 and 15.
  • FIG. 17 a typical yarn feed is illustrated in that air is aspirated into the needle 34 to suck the yarn 20 into the radial opening 22 until it bottoms on the Patented Oct. .22, 1974 "ice bottom 36 of the opening.
  • the passage 38 can be vented to atmosphere to allow the yarn to be more readily fed into the opening 22.
  • the length of the yarn 20 to be cut is de termined by the depth of the opening 22 but other devices, such as a solenoid controlled stepping motor, can be used to deliver a desired length of yarn into the opening 22. As shown in FIGS.
  • the yarn bits are cut from the ,yarn supplies 20 and 21 by a fixed knife blade 40, or other suitable means such as a shear, band knife or sickle bar cutter, located adjacent the yarn supply so that it engages the yarn as the yarn distributor rotates to sever the bits from the yarn supply.
  • a fixed knife blade 40 or other suitable means such as a shear, band knife or sickle bar cutter, located adjacent the yarn supply so that it engages the yarn as the yarn distributor rotates to sever the bits from the yarn supply.
  • FIGS. 9-11 show the preferred yarn releaseand bit inserter device and FIGS. 12 and 13 show-an alternative device.
  • FIGS. 911 when the cyliner 12 rotates to a position vvhere one of the radial holes, such as 22, is lined up with the hollow needle 42 and it is desired to insert the bit of yarn 16 into the adhesive layer 30, the passage 38 is vented to atmosphere and air is aspirated into the needle 42 through opening 44 to insert the yarn bit 16 into the adhesive layer 30. Then the conveying surface 32 is moved downward (FIG. 10) so that the yarn bit 16 clears the bottom of the needle 42. Then the conveying surface is moved downstream from the needle and upward for receipt of another row of yarn bits if the row of yarn is complete with the proper colors. At the same time the cylinder 12 has rotated counterclockwise to place another radial opening, such as 28, into communicationwith the hollow needle 42. 1
  • FIGS. 12 and 13 illustrate another type of yarn inserter which may be employed to implant yarn bits 16 into the adhesive layer 30.
  • the yarn inserter of FIGS. 12 and 13 is a mechanical type which uses a plunger 45 and plunger rod 46 to mechanically push the yarn bit 16 into the adhesive surface 30.
  • the plunger 46 can be actuated by any suitable means such as a cam, solenoid, etc.
  • FIGS. l-S represent schematically the operation of one disc ofone cylinder 10.
  • the control of the yarn into and out of the radial opening, as well as the rotation of the cylinder 10, is automatic and preselected to provide the desired effect in the finished product.
  • N represents the number of yarn colors required
  • the discs 12 will have 2N openings therein as indicated by the openings 22, 24, 26 and 28 since a two color yarn effect is desired.
  • the number of openings in the disc 12 for any N is such that there will be N openings in a position to be fed yarn.
  • N1 openings empty or idle and one opening in a position to release yarn into the adhesive layer.
  • each indexing rotation of the cylinder 10 is 1r/ N radians.
  • the maximum number of indexes necessary for a given yarn color to become available at the release station at a given place in the pattern also will be N.
  • the cylinder 10 will be rotated or indexed N times before the backing 32 is moved to make another row in the carpet.
  • one color yarn is supplied only to openings 22 and 26 while the other color yarn is supplied to openings 24 and 28.
  • the controls are programmed to do so, one color yarn 20 is being supplied to opening 22 while another color yarn 21 is being supplied to the opening 24.
  • the conveying surface 32 is moved downward, indexed one space to receive:another row of yarn bits and moved back up into yarn receiving position.'At the same time, yarn sup- ,ply 20 is supplying yarn into opening 26 and'yarn sup- .ply 21 is supplying yarn into opening 28. Then the procedure is repeated to provide another row of yarn bits.
  • FIGS. l-S a modification of the system shown in FIGS. l-S is schematically represented.
  • the reference number 16 represents one color yarn and the reference number 18 represents another color yarn.
  • the letters A-E represent discs 12 in the cylinder 10 and the letters R R R R and R represent rows of yarn bits.
  • the yarn bits are supplied and released in the manner previously disclosed.
  • the supply and release actuation devices are programmed on a computer which, at the predetermined time for the particular desired pattern, ac? tuates the actuators.
  • FIG. 18 represents a two color repeat pattern but obviously any number of yarns and patterns can be employed within the physical capabilities of the apparatus.
  • R represents the first row in the carpet being produced and bottom openings of A, B and E are supplying yarn bits 16 and bottom openings of C and D are supplying yarn bits 18.
  • yarn for bits 16 to be released at row R are being supplied to C and D while yarn for bits 18 are being supplied as and C for release at row R
  • the discs 12 are rotated to the R position where A, D and E release yarn bits 16 and B and C release yarn bits 18.
  • yarn for bits 16 are being supplied to B and C for release at row R while yarn is being supplied to 1A, B and E for release at row 3 .7 s
  • the discs are rotated to row R, where A,
  • the herein-disclosed invention provides apparatus and methods which can be computer controlled for manufacturing bonded, cut pile carpets with colored yarn patterning capability.
