Detailed description of the invention
Below, with reference to the accompanying drawings one embodiment of the present invention is described.The heddle for weaving machine 10 of present embodiment is formed by synthetic resin board stamping-out.Synthetic resin comprises polyethylene terephthalate (PET) and PEN (PEN), it contains the PEN of 10 quality % ~ 30 quality %, preferably 15 quality % ~ 25 quality %, more preferably 18 quality % ~ 20 quality %.
Heddle for weaving machine 10 is formed in mode symmetrical in the longitudinal direction, is formed as flat elongate.At one end portion 10a and the other end 10b is formed with elongated installing hole 12a, 12b of supplying the mounting rod 22 of heald frame 20 described later to run through.This heddle for weaving machine 10 entirety is formed as uniform thickness, and its thickness is formed as 0.35mm ~ 0.60mm, preferably 0.40mm ~ 0.55mm, more preferably 0.45mm ~ 0.50mm.The central portion 10c of heddle for weaving machine 10 is formed with a pair torsional part 10d of part to twisted of the predetermined space by comprising central portion 10c.Such as when total length is heddle for weaving machine 10 of about 150mm length, the interval between torsional part 10d is about 20mm, suitably can set in the scope of 15mm ~ 30mm.The windup-degree of torsional part 10d is 10 ° ~ 35 °, preferably 15 ° ~ 30 °, more preferably 20 ° ~ 25 °.
Heddle for weaving machine 10 central authorities and be formed with in the central authorities of torsional part 10d part the warp thread through hole 14 run through for warp thread 24.Warp thread through hole 14 is formed as the oblong-shaped of the R portion 14a being formed with chamfering, when the angle views reversed from torsional part 10d, is formed as roughly foursquare through hole.The radius of curvature of the R portion 14a of the bight 14a of warp thread through hole 14 is greater than the diameter of warp thread 24, thus warp thread 24 not easily fluffs because of friction.
As shown in Figure 6, by making the mounting rod 22 formed on the heald frame 20 of the metallic plates such as stainless steel be entrenched in the installing hole 12a of heddle for weaving machine 10, thus heddle for weaving machine 10 is installed on heald frame component 30.Mounting rod 22 is separately positioned on the both sides up and down in the inner part of heald frame 20 in the mode that the frame portion 20a with upper and lower is parallel, and have at the central portion of mounting rod 22 and form cut portion 22a, a pair mounting rod 22 of cantilever position is set as and makes its top ends 22b toward each other.The not shown mounting rod of the downside of heald frame 20 is entrenched in the installing hole 12b of heddle for weaving machine 10 similarly, and predetermined heddle for weaving machine 10 is arranged on heald frame 20 with constant interval.
At this, the width of mounting rod 22 is degree slightly narrower than the length of installing hole 12a, 12b, is formed as can not producing larger rocking when knitting braking and doing.Further, on the frame portion 20a above being positioned at of heald frame 20, utilize screw 28 to be fixed with heddle (heald) pressing member 26, thus eliminate rocking when heddle for weaving machine 10 is installed on heald frame 20.Equally also in the frame portion being positioned at below of heald frame 20, heddle (heald) pressing member 26 can be also installed.Thereby, it is possible to suppress heddle for weaving machine 10 rocking in below.
Then, the heddle for weaving machine 10 of present embodiment and the action effect of heald frame component 30 are described.First, the installation of heald frame component 30 to loom is described.The heald frame component 30 being provided with the heddle for weaving machine 10 of predetermined radical is provided with at least one pair of on loom, and they pump along opposite directions, between warp thread 24, form the opening inserted for weft yarn and shed open.Usually in heald frame component 30, run through 8 warp thread 24, and 8 heald frame components 30 are arranged on loom, knit the chain band etc. that width processed is the slide fastener of about 12mm ~ 17mm.Thus, when using such as 60 heddle for weaving machine 10, when its thickness is 0.4mm, even if only heddle for weaving machine 10 is piled up thickness 24mm will be reached, thus need the width more much bigger than the bandwidth will knitting system.In addition, preferably, at wefting insertion and the position of beat up (Japanese: Cheng beats Chi), the two ends gap-forming of warp thread 24 is roughly bandwidth, and at the stop position to warp thread 24 wefting insertion, the warp thread 24 at heald frame component 30 two ends is each other as far as possible close to parallel.Thus, in order to the warp thread 24 at the two ends in 60 warp thread is transported to insertion position to connect subparallel angle each other as far as possible, the interval between heald frame component 30 and insertion position must be guaranteed, thus cause the maximization of loom, therefore unsatisfactory.Therefore, preferred heddle for weaving machine 10 is as far as possible thin, when metal heddle (heald) in the past, can obtain sufficient intensity, therefore, and the thickness of the heddle (heald) of the short dimensions of below length 30cm normally 0.25mm ~ 0.30mm.
When the loom of common broad fabrics, loom, from as large-scale, as long as adopt metal heddle (heald), would not produce the problem of the problem of the thickness of above-mentioned heddle for weaving machine 10 and the angled conveyor of warp thread 24.But, when weaving the such smallware of slide fastener chain band, because the wefting insertion distance of weft yarn is also shorter, therefore, the reciprocating motion of heald frame component 30 also can high speed, and from the viewpoint of knitting efficiency processed, the rotating speed of loom is also significantly higher than loom rotating speed when knitting broad fabrics processed.When the rotating speed of loom improves, larger inertia force can be acted on to reciprocating heddle for weaving machine 10, thus require higher intensity while rotating speed increases.
Thus, when resinous heddle for weaving machine 10, there is such problem of runing counter to: preferably heddle for weaving machine 10 is as far as possible thin in order to the distance till shortening to insertion position, and require that certain thickness is to guarantee required intensity in order to the high speed realizing loom.
Therefore, in the present invention, the maximization of loom can be suppressed and can guarantee the thickness of resinous heddle for weaving machine 10 of intensity of High Rotation Speed to be 0.35mm ~ 0.60mm, being preferably 0.40mm ~ 0.55mm, being more preferably 0.45mm ~ 0.50mm.And the contraction in length of resinous heddle for weaving machine 10 is 160mm ~ 140mm, is preferably 155mm ~ 145mm, is more preferably 150mm.And, because resin material comprises polyethylene terephthalate (PET) and PEN (PEN), therefore, the content of PEN is set to 10 quality % ~ 30 quality %, is preferably 15 quality % ~ 25 quality %, is more preferably 18 quality % ~ 20 quality %, thus reach the balance between cost and the strength of materials.Thereby, it is possible to the fed distance of the same warp thread 24 of the fed distance and loom rotating speed with the warp thread 24 during metal heddle (heald) and loom rotating speed, the braking of knitting using resinous heddle for weaving machine 10 to carry out chain band is done.
Usually, when knitting the smallwares such as chain band processed, consider from the structure of ribbon structure and the efficiency these two aspects of braid movement, expect can to run through 18 ~ 22 in a heald frame component 30, be preferably the mode of 20 warp thread 24 to configure heddle for weaving machine 10.In addition, run through and have the heald frame component 30 of 20 warp thread 24 to be frames of plain weave, other frame is the frame of twill-weave, satin weave.In addition, known following content: the width of common chain band is about 12mm ~ 17mm, desirably, as previously mentioned, the position of beating up, the warp thread 24 at two ends is as far as possible parallel to each other each other, specifically, desirably, in the configuration relation shown in Fig. 8, when the width of chain band 32 being set to xmm, the interval between the warp thread 24 at the two ends of foremost heald frame component 30 is set to α xmm, when the distance from the fell 34a utilizing reed 34 to carry out beating up to foremost heald frame component 30 is set to Lmm, 1≤α≤0.0167L.Its reason is, when being set to more than the above-mentioned upper limit by α, can hindering the motion of anterior reed (Japanese: Off ロ Application ト リ ー De) or producing harmful effects such as warp thread 24 damage.Thus, when such as L=70mm, if x=12mm, then upper limit width is 14.0mm, if x=17mm, then upper limit width is 19.9mm.When heald frame component 30 is designed to weave the most narrow x=12mm, if use as plain weave and arrange 20 heddle for weaving machine 10 on this heald frame component 30, then the upper thickness limit of each root of the heddle for weaving machine 10 of just merely lining up is 0.7mm.But, due to must gap be had between heddle for weaving machine 10, therefore, the condition that the thickness of heddle for weaving machine 10 is set to more than 0.6mm for slide fastener chain band with for unsatisfactory.
Adopt the heddle for weaving machine 10 of described above, embodiments of the present invention, heald frame component 30 and loom, space processed can be knitted and loom rotating speed knits the smallwares such as chain band processed expeditiously with same with metal heddle (heald).And, by adopting resinous heddle for weaving machine 10, the quality of heald frame component 30 entirety can be made to alleviate, and heald frame 20 also can reduce intensity and lightweight, therefore, it is possible to suppress to drive power, can reduce significantly drive can, noise.Further, can not produce metal powder as metal heddle (heald), fabric can not be made dirty by metal powder.Even if resinous heddle for weaving machine 10 produces wearing and tearing due to passing through of warp thread 24, knit system fabric also can not occur suddenly bad, reliably can change heddle for weaving machine 10 before generation is bad.In addition, owing to utilizing heddle (heald) pressing member 26 to inhibit rocking of heddle for weaving machine 10, therefore, noise when knitting processed alleviates, and the durability of heddle for weaving machine 10 also strengthens.
In addition, heddle for weaving machine of the present invention, heald frame component and adopt the loom of this heddle for weaving machine and heald frame component to be not limited to above-mentioned embodiment, a pair torsional part of part to twisted of the predetermined space by comprising central portion can not be formed at the central portion of heddle for weaving machine yet, also can be, warp thread through hole be not be formed as arc-shaped with bight, quadrangle that mode that an opposite side is positioned at horizontal direction is formed.In addition, for the kind of resin, as long as certain intensity can be maintained, the resin material except above-mentioned material can just be adopted.Further, except being formed by synthetic resin board stamping-out, also can by utilizing the resin formings such as injection moulding to be formed.
