Definitions

  • ABSTRACT A ganged tufting needle unit having a multiplicity of parallel needles formed integral with a common holder which includes a pair of reference surfaces and is adopted to be accurately attached as a unit to a needle bar of a tufting machine.
  • the holder is divided into standardized sections by score lines at predetermined needle intervals along its length so that if one or more needles should break the section including the broken needles can be separated from the remainder of the unit and a standard replacement unit may be readily substituted therefor.
  • a latch needle unit and a yarn guide unit having thesame features as the tufting needle unit. A method for manufacturing the different units from a metal strip comprising a series of die pressing, punching and grinding steps is described.
  • This invention relates to yarn-handling instrumentalities and more particularly to a ganged unit having a plurality of yarn-handling fingers unitary with a common support for use in tufting or knitting machines.
  • Carpets and similar tufted articles are manufactured by pushing yarn through a backing material to produce loops on one side thereof.
  • Machines that perform this process are known in the art as tufting machines and comprise a transversely extending needle bar carrying a multiplicity of needles which carry the yarn and pierce the backing fabric, a needle plate supporting a longitudinally moving backing fabric and having a multiplicity of holes through which the needles pass after piercing the fabric, and a multiplicity of loopers generally located below the needle plate for engaging the yarn carried by respective needles after the latter have passed through the backing fabric and the needle plate.
  • a machine of this general type is illustrated in US. Pat. No. 3,108,553.
  • each yarn-carrying needle must properly cooperate with its corresponding looper.
  • the needle eye and the yarn groove in the needle must be properly positioned relative to the looper so that the loop formed will be available to the looper.
  • the needle must pass close enough to the looper so that the latter may pick up a loop, but it should not pass so close to the looper that contact would occur resulting in damage to the needle or looper.
  • the position of the needle relative to the looper thus being critical, it has been the practice to incorporate in such machines a needle bar having a multiplicity of extremely accurately bored needle-receiving holes. Each needle must then individually be fitted, adjusted and fastened in the needle bar relative to the looper.
  • An illustration of a needle bar of such construction can be found in US. Pat. No. 3,398,708.
  • tufting machines may contain as many as 3,000 needles
  • the needle bar must be accurately bored to accommodate this sum. This, of course, can be a very costly procedure.
  • each needle since each needle must be individually inserted into a bore and adjusted and fastened therein, it becomes a costly, tedious and time-consuming process to set up a tufting machine for proper operation and to later replace needles broken during the subsequent tufting operation.
  • the yarn guides are bladelike devices having a hole in one end lightweight which are used in Raschel and tricot machines to guide the feeding of yarn to the needles.
  • the guides in these machines in order to properly align them relative to each other, are set in guide leads, i.e., cast in leaded units, which are in turn bolted to a guide bar. This is also true of the needles in these machines.
  • the guides and needles that are so embedded in lead must be properly anchored therein to prevent extraction during the knitting operation. This requires that some type of anchoring aid, such as a notch, must be formed in the shanks, thus adding to the complexity and cost of the unit.
  • a further deficiency of the present systems is that the heavy mass of lead into which the needles and guides are cast provide an obstacle to the attainment of high-speed operation.
  • An approach to the reduction of the large mass resulted in mounting the needles directly in the respective bars, but this was found to be inadequate for the same reasons stated in regard to tufting.
  • Applicants invention overcomes these difficulties of the prior tufting and knitting arts by providing a unit having a multiplicity of similar yarn-handling instrumentalities of one-piece construction that together with like units may be quickly and accurately fastened in the machine.
  • a multineedle unit of the tufting type which is adopted to be applied to a less expensive needle bar of a tufting machine.
  • a multineedle unit of the latch type for a Raschel knitting machine.
  • a third embodiment provides a multiyam guide unit which is adopted to be used in a warp knitting machine.
  • each fingerlike element has a free end which is shaped to engage and control a strand of yarn.
  • the fingerlike element may be a tufting needle, a latch needle or a yarn guide.
  • Each of the units may be economically manufactured by a process comprising a series of punching, stamping and twisting steps to form each fingerlike element simultaneously.
  • a further object of this invention is to provide a multineedle unit adapted for use in a tufting machine which obviates the need for a needle bar having a multiplicity of accurately machined needle bores.
  • a still further object of this invention is the provision of a multineedle unit of the latch type adapted for use in a warp knitting machine which unit is light in weight so as not to present an obstacle to high-speed operation.
  • a yet still further object of this invention is to provide a light-wwight multiyam guide unit adapted for use in a knitting machine.
  • the inevitable needle breakages that occur during tufting and knitting operations are provided for and economically dealt with by the present invention by scoring the units at predetermined intervals along the length thereof and providing standard ready replacement units.
  • the subunit containing the broken instrumentality or instrumentalities may be separated along the score lines from the remainder of the unit and a replacement subunit readily substituted therefor with a minimum of downtime.
  • FIG. I is a fragmentary perspective view of tufting needle units of the present invention fastened to a needle bar shown broken away, with one needle shown in cross section;
  • FIG. 2 is an elevational end view of one tufting needle unit of FIG. 1 as viewed from the right end of FIG. 1;
  • FIG. 3 is an elevational end view of one tufting needle unit of FIG. 1 as viewed from the left end of FIG. 1;
  • FIG. 6 is a view similar to FIG. 5 after punching or stamping the metal displaced during die-pressing;
  • FIG. 7 is a cross sectional view along line 77 of FIG. 6, but after the eye of the needle has been rounded by punching;
  • FIG. 9 is a fragmentary view of a typical latch needle showing its component parts
  • FIG. It is an end elevational view of one latch needle unit of the present invention before assembly of the latches thereto;
  • FIG. 11 is a view similar to FIG. 4 showing the fingers formed in a metal blank used to form the latch needle unit;
  • FIG. 13 is a view similar to FIG. 12 after punching or stamping the metal displaced during die-pressing;
  • FIG. 15 is an end elevational view of one yarn guide unit of the present invention.
  • FIG. 16 is a fragmentary front elevational view of a yarn guide unit being formed showing the result of the die-pressing step to form the contour of the guides and the eye therein;
  • FIG. 17 is a view similar to FIG. I6 after punching or stamping the metal displaced during die-pressing.
  • FIG. 18 is a fragmentary front elevational view of the completed yarn guide unit.
  • FIG. I there is disclosed a preferred embodiment of the tufting needle units of this invention fastened to a needle bar 10 ofa tufting machine (not shown).
  • a complete basic needle unit 12 is shown having a rectangular-shaped common holder, shank or support section 14 and a multiplicity of needles 16 formed unitary therewith.
  • the unit is mounted in complementary fashion along the needle bar with a plurality of similar units, a portion of a second such unit being shown in FIG. 1.
  • the number of needles selected for the unit disclosed is l2, it should be appreciated that this number depends on several factors: one being the economical production of the unit itself and another being the number of needles selected for standard replacement units. It should be appreciated, therefore, that the precise number of needles disclosed should not limit the scope of the present invention.
  • the needle units of the present invention obviate the prior art requirements of accurately boring a multiplicity of needlereceiving holes in the needle bar and of individually inserting and adjusting each needle in a bored hole. Inasmuch as precisely milled slots are simpler to produce than precisely bored holes, a greater accuracy of alignment of the needles relative to the tufting machine loopers and a more economically produced needle bar are possible with the present invention.
  • Each needle 16 comprises a unitary projection extending in cantilever fashion from the shank I4 of the unit.
  • a long groove 28 defined by ridges 30, which act to guide the yarn therein during needle penetration of the tufted fabric, as is well known in the art.
  • the groove 28 extends from front surface 32 of the shank l4 and terminates at needle eye 34 adjacent to and slightly above point 36.
  • the present needles have a larger cross-sectional dimension in a direction transverse to the needle eye then in a direction parallel to the needle eye. This can be seen in FIG. 1 by cross-sectional needle 17, i.e., the fourth needle from the right.
  • the present needles inasmuch as they can be economically produced from a relatively long flat strip of metal, as will be presently described, are twisted about their longitudinal axes so that when inserted into a tufting machine the groove 28 and the needle eye 34 will be in proper functional relationship with the looper.
  • the twist is The position of the looper relative to the needle instrumentalities, as shown in the aforementioned US. Pat. No. 3,398,708, is in a vertical plane transverse to the longitudinal axis of the needle bar.
  • Each basic unit 12 is subdivided as by indentations or readily shearable score lines 40 and 42 into a number of subunits 44, 46 and 48.
  • the score lines are, of course, parallel to the needles. It is to be understood that the number of subunits depends on the number of needles in the basic unit 12 and the number of needles selected for standard replacement units.
  • a standard replacement unit 50 having four needles is shown mounted on the needle bar 10 adjacent the basic unit I2. It should be obvious that in the event of a needle breakage occurring in one of the needle subunits 44, 46 or 48 this subunit may be separated along the appropriate score line 40 or 42 or both from the remainder of the basic unit 12 and a standard replacement unit 50 substituted in its place.
  • either two or more standard replacement units may be inserted, or a replacement unit comprising twice or thrice etc. the number of needles of a standard replacement unit may be inserted.
  • the replacement units may be produced as offthe-shelf ready replacement items or may be produced from new or used basic needle units. This principle or modulus assembly allows a very quick, efficient and economical replacement of broken needles, thus reducing the machine downtime.
  • FIG. 5 is next subjected to a punching or stamping operation to remove the excess material 54 displaced during the press-forming step, the result thereof being shown in FIG. 6.
  • the blank is now subjected to a pair of punching dies on opposite sides of the eye and the eye is rounded along both its top surface 56 and bottom surface 53 as shown in FIG. 7.
  • the needles are then pointed on their two outer tips 60 and 62 by grinding the proper point angles.
  • the needles are twisted preferably through 90 about their longitudinal axes so that the eyes and the yarn grooves are set into proper position for cooperation with a looper upon later fastening in a tufting machine.
  • This twisting step coaxially aligns the eyes of all the needles and positions surfaces 64 and 66 available to a grinding operation.
  • the final grinding of the point angles is then performed thereon.
  • the needle unit is now ready for the reference surfaces 18 and 20 to be ground thereon and for the fastening holes 24 to be punched therein. At least one such hole must be punched in each intended subunit.
  • the shanks of the units are sharply scored by, for example, indentations ground therein, and the units are cut to length. Of course, the proper heat treatment will then follow.
  • the above process may be used to manufacture larger gauge units and two or more such units may then be superposed upon each other in staggered relationship so that needles of one unit are disposed between needles of the other unit or units, or two or more staggered rows of such units may be set in a needle bar having two or more milled slots.
  • the latch needle unit of the present invention includes a common shank section 75 having at least a rear reference surface 76 and preferably a top reference surface 77 which are similar to the reference surfaces of the tufting needle unit, and which can cooperate with the knitting machine mounting surface.
  • the unit with the exception of the specific needle configuration, is in all other respects similar to the aforedescribed tufting needle unit and may be manufactured and scored in like manner.
  • FIGS. 11 through 13 show the steps of a method for manufacturing the latch needle unit beginning with a blank with fingers 78 formed therein similar to the fingers 52 shown in FIG. 4. The blank is then subjected to a die press forming or fine flow stamping operation to contour the needles and form the rivot hole 79 as shown in FIG. 12.
  • the blank is next punched or stamped to remove the excess material 80 displaced during the press-forming step.
  • the needles of the unit now in the condition shown in FIG. 13, are then twisted 90 about their longitudinal axes so that they are properly oriented for later insertion into a knitting machine. This twisting step coaxially aligns the rivet holes of all the needles and positions the stem so that the latch slot may then be cut therein.
  • the reference surfaces may now be ground thereon and fastening holes formed therein. Scoring and cutting of the units to length then follows.
  • FIGS. 15 through 18 the present invention is applied, as another embodiment, to yarn guides used in the knitting operation to guide yarn to the knitting point.
  • An eye 90 at the bulbous free end 91 of the finger element acts to guide yarn passing therethrough.
  • the unit is similar in all respects to the needle units previously described and includes a common shank 92 having at least a rear reference surface 93 and also preferably a top reference surface 94 for mounting in a knitting machine.
