Definitions

the invention relates to a device for producing a seersucker fabric on weaving machines, whereby the finished fabric consisting of base warp threads, effect or pile warp threads and weft threads has an oscillating forward and backward movement superimposed at the binding point of the normal fabric withdrawal movement in a rhythm of 1: 1, equal to the plain weave characteristic of seersucker , is communicated in such a way that the effect or pile warp threads are given a length allowance in comparison to the basic warp threads and the device is connected to a drive derived from the main gear of the weaving machine.
the necessary differential movement between the base warp sheet and the effect or pile warp sheet is achieved so that the length allowance was achieved by the naturally different tensions (tension difference between the effect or pile warp sheet and the base warp sheet).
tension difference between the effect or pile warp sheet and the base warp sheet are achieved in the prior art see also EP-A-0 352 791 by a different drive of the pile warp beam compared to the basic warp beam of the weaving machine.
the intended length addition for the effect or pile warp threads can only be achieved more or less by chance. It is therefore only possible to adjust the length allowance with relatively large variations. So far, when the weft thread is struck, the slightly more smoothly adjusted effect or pile warp threads are carried more strongly than the basic warp threads, which results in the desired length addition.
the invention as set out in claim 1, characterized in that on the output side of the weaving machine after the weaving point of the fabric, a first shaft, which extends over the width of the weaving machine, is rotatably movable at its free ends by one in the respective weaving machine -Housing wall is supported bearing and an eccentric disc is fixedly connected to the first shaft near the bearing in question and wherein each eccentric disc is in operative connection with a scanning roller of a rotatably arranged on a bearing plate roller lever and wherein each roller lever via a coupling with an oscillating in the area of is connected to the aforementioned bearing plate associated clamp holder and wherein the clamp holder also receive the free ends of a second shaft extending across the weaving machine width, and which clamp holder are received in a pivot bearing arranged eccentrically to the longitudinal axis of the second shaft.
the first shaft of the device according to the invention is connected with respect to its drive to a drive derived from the main gear of the weaving machine.
the oscillation movement can be generated in several ways. So it is also conceivable, for example, to provide two mutually displaceable rollers, each of which can be fed onto the tissue, the rollers then taking up the tissue between them in the manner of a shear effect and being pivoted at right angles to the plane of the tissue, so that this also results in one Back and forth movement of the tissue is achieved.
the invention therefore treads a completely new path in that it is proposed for the first time that the oscillating movement only be carried out on the exit side of the weaving machine and thus on the finished fabric, that is to say behind and as close as possible to the weaving point of the fabric, which is crucial.
the pivotable arm arranged behind the warp beam with the deflection shaft is designed with as little mass as possible.
the deflecting shaft will be designed as a hollow shaft and the swivel arm with its deflecting shaft will be made of light metal (light material).
the pile chain is driven by a motor that can be controlled as precisely as possible in terms of speed and torque.
a conventional weaving machine is provided, which is still modified on the inlet side, as will be explained in more detail below.
the device 1 according to the invention is provided on the outlet side, which is arranged in the vicinity of the drawing-in roller 2 of the weaving machine and over which the fabric 3 runs (cf. FIG. 1).
Shafts 6 are available.
the compartment 4 is thus formed as a front compartment, while the rear compartment 7 is formed beyond the shafts.
a deflecting shaft 13 is also fixedly arranged on the superstructure bracket 25 and serves to deflect the effect or pile warp threads 14 which are pulled off the pile warp beam 15.
the pivot arm 12 is pivotally mounted, its pivot point 16 being adjustable in the arrow directions 17. This makes it possible to influence the rear compartment 7 in the altitude.
the sensor shaft 11 has the task of acting simultaneously as a coating roller and as a dancer roller. It is important here that the effect or pile warp yarn sheet 14 is not divided by the arm 12 itself, because the sheet is deflected beyond the arm 12 via the sensing shaft 11.
the pile warp beam 15 is motor-driven by a drive (not shown in more detail) via a motor that is precisely regulated in terms of speed and torque in order to ensure a low-tension withdrawal of the effect or pile warp threads 14.
the swivel arm 12 is acted upon in the arrow direction 18 by a spring arrangement (not shown in more detail), so that it receives a certain pretension in the arrow direction 18 in order to load the effect or pile warp thread family 14 with a pretension, which, however, is very slight.
the sensing shaft 11 thus pivots in the arrow directions 18, 19 shown about the pivot point 16.
the swivel arm 12 serves as a sensing arm. That is to say, at position 20, a machine-specific proximity switch is arranged, to which a corresponding actuating element 21 on the sensing arm 12 is assigned.
the distance 22 between these two elements is closely monitored by control electronics. This distance 22 is used as a control variable for controlling the speed of rotation for driving the pile chain beam 15. This ensures that the set of effect or pile warp threads 14 is always pulled off the pile warp beam 15 with a constant tension.
the swivel arm 12 is designed with as little mass as possible in order to ensure a quick reaction.
the sensing shaft 11 is formed from a thin-walled, hollow material;
the swivel arm 12 is dimensioned as small as possible and made from a light metal material, for example aluminum or the like.
the pivot bearing in the pivot point 16 is designed as smoothly as possible, e.g. designed as a ball bearing.
the pivot arms 12 are on a common shaft, i.e. thus mounted on a common pivot point 16 which - as stated above - is vertically adjustable in the arrow directions 17.
the fabric 3 is allowed to oscillate beyond the binding point 5 in order to achieve the desired high length addition in the case of effect or pile warp threads in comparison to the basic warp threads.
the device consists in particular of a shaft 44 on which two eccentric disks 45 are arranged in a rotationally fixed manner at a mutual distance.
the shaft is supported on the vertical side walls of the weaving machine housing 46. This shaft together with the shaft 36 extend over the entire width of the loom.
FIG. 2 only one right-hand eccentric disk 45 is shown, while on the opposite side of the machine 46 a similar, identical eccentric disc is arranged.
a roller lever 27 is pivotally mounted in a pivot bearing 28, a roller 29 running on the eccentric 45.
the roller 29 is pressed against the eccentric disk 45 via a coupling 30, the coupling 30 consisting in particular of two joint rod heads 31 and 32, the joint rod head 31 engaging in an elongated hole 33 and being continuously displaceable there.
the other joint rod head 32 is pivotally articulated on a clamp holder 34, which clamp holder 34 is pivotably mounted in a pivot bearing 35 on the bearing plate 26.
the clamp holder 34 clamps a shaft 36, the clamp holder being shown in two different pivot positions.
a pivot position is designated with position 34 '.
the function of the device is as follows:
the fabric 3 comes into the device 1 as a dashed line 37 (FIG. 2) and is deflected downward via the shaft 36.
the shaft 36 is driven oscillating in the arrow directions 38 around the pivot bearing 35.
the drive takes place via the eccentric disc 45, which rests non-positively on the roller 29.
the roller 29 is deflected around the pivot bearing 28 and, via the infinitely adjustable coupling 30, the clamp holder 34 is pivotally driven in the arrow directions 38 around the bearing 35. So there is an oscillating movement, the frequency of which depends on the speed of the eccentric discs 45.
One rotation of the eccentric discs 45 takes place per shot, so that an oscillating movement per Shot takes place.
the entire tissue 3 is informed of an oscillating movement in the arrow directions 40, 41.
This ensures that the effect or pile warp sheet 14 and the base warp sheet 24 are carried forward in the direction of arrow 41, but when moving back in the direction of arrow 40, the smoothly pivoting arm 12 ensures that the effect or pile warp sheet 14 remains, while the base warp sheet 24, which is under higher tension, due to its spring load, is relieved and thus decreases.
the spring loading is achieved in a manner known per se by the basic match tree 42, which is spring-loaded and thus tensions the basic warp thread family in the direction of arrow 40.
the base warp yarn sheet 24 will move backwards (also in the arrow direction 40) and take a larger path, while the pile warp yarn sheet 14 is not moved in the arrow direction 40 but remains there.
the size of the desired length allowance can be set on the coupling 30.
a length allowance could thus be set within relatively wide limits because this only depends on the setting of this device 1. Experiments by the applicant have shown that length addition of more than 41% is easy to achieve. The maximum upper limit is limited by the fabric properties.
