Definitions

  • the invention relates to a method for producing a webbing of the type mentioned in the preamble of claim 1.
  • Such a method is known from German Offenlegungsschrift 27 19 382 by the same applicant.
  • Belt straps produced in this way are mainly used for seat belts in motor vehicles.
  • the use of a needle ribbon weaving machine requires the formation of a knitting course to close the one hollow edge.
  • the course of stitches is moved to the edge of the middle part, and loops are drawn from the course of stitches into the middle part, so that the course of stitches practically disappears in the fabric.
  • weft needle The weft insertion needle (hereinafter referred to as "weft needle”) must be inserted twice in succession into the same compartment formed for the middle part.
  • the compartments are changed only for the edge parts, so that in each case one weft produces the edge part fabric and the next binds only with one of the two outermost warp threads and then serves to pull the edge part towards the hollow edge.
  • the present invention is intended to increase, in particular to double, the weft insertion rate. However, it should not be foregone the advantage outlined above that the stitch row practically disappears in the fabric of the belt.
  • weft needles instead of using a single one, two weft needles are used, but each insert a weft at the same time. You get twice the weft insertion performance at the same weaving speed. That means twice the length of the webbing per time unit.
  • the knitting needle is guided such that it pulls a loop (one of the weft threads or a catch thread) through a loop of the other weft thread or both weft threads and forms a stitch.
  • the two edge parts are then closed to form hollow edges. From the row of stitches formed on one edge part, a loop is also pulled into the fabric of the middle part, as after the previous publication.
  • Characteristic i takes into account the different lengths of the two shots, because only one of them forms the hollow edges and must therefore be longer than the other, which only forms the middle part.
  • German laid-open specification 21 61 013 describes a weaving process in which two weft needles are used and a row of stitches is formed from one weft thread with an auxiliary thread at one edge of the fabric. However, no hollow edge is formed here, but both weft threads are guided to the edge of the fabric. This publication consequently does not teach how to proceed if one wants to form a hollow edge with the simultaneous insertion of two weft needles, i.e. when both weft needles have two very different tasks to perform.
  • wefts of different fineness can be used. You can therefore by skillful combination of two shot materials of different levels achieve tapes with qualities that do not correspond to subtleties customary in Barcelona.
  • the strip thickness and the transverse stiffness can be chosen as desired without changing the weft density by using two weft threads of different strengths.
  • a monofilament can be used for the second weft.
  • the second weft thread is used to pull the single-ply edge part to the hollow edge, but is not used to produce the edge part fabric.
  • Monofilaments are harder than the multifiles normally used. By weaving with monofilaments as weft threads, it is therefore possible to achieve tapes with high transverse rigidity, which is very advantageous for winding in automatic reels. Monofilaments, on the other hand, would be more abrasive to clothing or body parts of the user if they appeared on the edge of the belt. This is avoided in that the monofilament is used only for the production of the middle part of the webbing and for pulling the single-ply edge parts, while these are themselves woven from a multifilament.
  • Using a relatively stiff monofilament for one of the weft threads allows weaving with a lower number of wefts per cm of tape length than when using two equally strong multifilaments as weft threads. This leads to a higher production speed.
  • catch thread and blocking thread can be fed through one and the same thread insert, which reduces the construction effort.
  • the invention further relates to a thread insert for a needle-band weaving machine for carrying out the method according to claim 9.
  • a thread insert for a needle-band weaving machine for carrying out the method according to claim 9.
  • Figure 1 shows in cross section the webbing to be produced with a left hollow edge 21, a right hollow edge 22 and the single-layer middle part 24.
  • the weft needles are inserted in the direction of arrow 26 and withdrawn in the opposite direction.
  • Both hollow edges are first produced as single-layer woven edge parts 21 'and 22'.
  • At the free edge of the edge part E s 22 ' we form a course 28'.
  • Both hollow edges d G rch train the weft closed.
  • the stitch row 28 ' is moved to the position 28 " where it disappears in the fabric of the belt.
  • loops are drawn from the stitch row into the single-layer middle part, as described in German Offenlegungsschrift 27 15 382.
  • FIGS. 2 and 3 fewer warp threads are shown both in the central part 24 and in one of the two edge parts 21 'and 22' than are normally used.
  • Figure 4 shows only the two outermost edge warp threads 1a and 2a.
  • the single-layer middle part 24 only one compartment is required, which is changed over in the manner known per se for a twill weave.
  • the cartridge according to FIG. 5 shows this for the shafts No. 5 to No. 12.
  • the middle part can also be woven using a double compartment.
  • a large compartment is formed by the two shafts No. 1 and No. 2, which is converted as for a linen weave. From the upper weft needle 30, the upper weft thread 31 is entered into this compartment. It alternately binds with the outermost and the second outermost warp threads 1a, 2a of the edge part 22 '.
  • a sub-compartment 32b is formed to produce the fabric of the two edge parts (FIGS. 2 and 5).
  • Half of the warp threads (4a) are pulled down by the associated strands, while the other half (3a) remains in a neutral position, i.e. in the middle.
  • the lower weft needle 34 carries the lower weft thread 35 into the lower compartment 32b.
  • Silk weft needles are inserted at the same time. With each weft, the middle part is woven in twill weave from both weft threads. The two edge parts are woven in a linen weave by the lower weft thread 35, while with each weft the upper weft thread 31 ties with one of the two outermost warp threads of both edge parts.
  • the knitting needle 37 which is movably arranged on the needle ribbon weaving machine, is carried out below the upper weft needle 30, specifically between the latter and the weft thread 31 coming from the ribbon fabric.
  • the knitting needle 37 is then guided along above the lower weft needle 34, in such a way that the lower weft thread 35 coming from the fabric is inserted into its open head.
  • a thread insert known per se and not shown here can be used to guide the lower weft thread 35 into the open head of the knitting needle.
  • all three needles 30, 34 and 37 are withdrawn into the layers according to FIG. 3.
  • the knitting needle 37 pulls a loop 35 'of the lower weft thread 35 through a loop 31' of the upper weft thread 31 and forms a stitch 28 by knocking off a loop 35 "hanging thereon from the previous weft.
  • the loop 35" was made from the lower weft thread 35 educated.
  • a blocking thread 41 can also be knitted into the course 28 '. As FIG. 3 shows, the blocking thread 41 is only knitted by the knitting needle 37 with the lower weft thread 35.
  • the two edge parts 21 'and 22' are closed by pulling on the upper weft thread 31 to form hollow edges, but this is not shown in FIG. 3.
  • the left edge part 21 ' is in each case during insertion the upper weft needle 30 is closed to the right to the hollow edge, the right edge part 22 'when the upper weft needle 30 is withdrawn to the left.
  • the stitch row 28 is drawn to the right edge of the middle part 24, and a loop from the weft thread 35 is drawn from the stitch row into the single-layer fabric of the middle part 24 by the upper weft thread 31,
  • the knitting needle 37 is pivotable about an axis running in the weft direction below the webbing, in such a way that it describes an arcuate path with little curvature.
  • Figure 6 shows the formation of a stitch row using a catch thread 51.
  • Figure 6 shows only the two outermost warp threads 1a and 2a with the shaft numbers 1 and 2 and shows very schematically indicated the wefts already entered and two weft threads 31 and 35, which are just from the two weft needles 30 and 34 are entered. Apart from the special features to be described below, the statements made above also apply to this part of the invention.
  • a thread insert 53 is used for feeding a catch thread 51 and a locking thread 41 together (FIG. 7).
  • the thread insert is pivotable about an axis at 54 towards the end and in the weft direction.
  • Figure 7 shows it in its uppermost operating position.
  • the thread insert has an arm 56 which ends at its right end in two extensions 58, 60, each of which has a thread eye 62, 63 at its free end.
  • the thread eye 62 is used for feeding the catch thread 51, the thread eye 63 for feeding the locking thread 41.
  • the extension 58 is curved approximately in a semicircle, while the extension 60 is straight and extends approximately in the direction of a diameter to the semicircular extension 58.
  • FIG. 7 shows the uppermost operating position of the thread insert 53 and the two weft needles 30 and 34.
  • the thread insert engages around both weft needles in this position. It feeds the catch thread 51 from below, but the blocking thread 41 from above, as shown in FIG. 6.
  • a loop 51 'from the catch thread is consequently pulled between the two weft needles 30 and 34 on the one hand and the two weft threads 31, 35 coming from the fabric on the other hand by the knitting needle 37.
  • a loop 51 "of the catch thread and a loop 41" of the locking thread hang from the previous weft.
  • the blocking thread 41 is also inserted into the open head of the knitting needle 37, the two loops 41 "and 51" are knocked off to form a new stitch 65.
  • the length of the weft thread 35 supplied must be greater than that of the weft thread 31. While the weft thread 31 essentially only forms the single-layer middle part 24, the weft thread 35 must also have the Form tissue of the two edge parts 21 ', 22'. In the embodiment according to FIGS. 2 to 4, the weft thread 35 must also be longer, since it also forms the course 28 'and loops are drawn out of this course into the single-layer middle part.
