Description

Facilities for manufacturing at least one knitted ribbon with crotch knitted rubber seals

In the case of normally knitted ribbons, the rubber yarn is insufficiently fastened and the knitted fabric slips around the rubber yarn when using the ribbon. In order to prevent this, a separate wrapped or crocheted rubber thread must be machined, which is very costly. Today, the following methods are known for the manufacture of knitted ribbons with non-slip rubber seals.

Naked rubber threads are coated in a coating machine. This process is a cost-intensive method that has to be performed on expensive and noisy machines. Another method is to coat the naked rubber threads by crochet knitting by a special crochet knitting machine. This method is more advantageous than the coating method, which is the first method, but it is still a cost-intensive method in terms of method and apparatus. Another drawback of the crochet knitting method at different angles is that the number of noses per unit length of the pre-crochet knitted rubber yarn must match the corresponding crochet number of the finished knitted ribbon, which is very much achievable due to the elasticity of the rubber yarn it's difficult. Since knitted ribbons and crotch knitted rubber yarns are produced separately temporally and spatially, there is also a problem of color matching of the warp yarns of the crochet knitting yarn and the knitted ribbon. The manufacture of a crocheted knitted rubber yarn, the intermediate storage of the rubber yarn, the blending of the rubber yarn with the knitted fabric ribbons produced, and the production of the knitted ribbons by winding the crocheted knitted rubber yarn on the rind are very complicated and cost intensive Subsequently, it is almost inapplicable to practical use.

The third method is to make knitted ribbons with naked rubber threads and at the same time knit the knit over the width of the ribbons. The disadvantage of this method is that the additional cost of the additional melt yarn and further melt processing as the other side, and the need for additional launch rods for the movement of the molten yarn.

It is also known to crotch the rubber yarn immediately after the production of the knitted ribbon from DE-A-43 28 951. To this end, two bonded yarns are used, one of which is a stationary bonded yarn, which always covers the same rubber yarn and the front and rear weft yarns. The other binder is also skipped and guided, covering only the weft yarn on one side and forming a nose around the first rubber yarn and also around a few wefts before and after the odd number of wefts. The second binder then weakens to the second rubber thread of the neighbor and forms the same number of sequential front and rear weft noses with this rubber thread. This manufacturing method is relatively complicated and the ribbons so manufactured have only insufficiently coated rubber seals and are therefore unsuitable for expensive products and only suitable for simple products such as cushioning ribbons.

It is known from DE-A-22 64 297 to mount a knitting machine for sheathing in looms. However, this facility is extremely complicated and costly because two principlely different textile machines, namely looms and knitting machines, are combined so that parts of one machine can not be used in another machine. On top of that, the synchronization of the two machines is difficult and this has an adverse effect on the manufactured fabric.

The present invention relates to a facility for manufacturing at least one knitted ribbon comprising a rubber thread of a crocheted knit according to the concept of claim 1.

The knitted fabric comprises a knitted fabric and a knitted fabric. 18 guide beam, 34 guide gap, 36 discharge device, 38 roll, 40 ribbon, knitting yarn, 20 ribbon knitting machine, 22 knitting machine, 24 knitting machine, 26 yarn, 26 beam, 28 knitting needle, 28a cloth knitting needle, Roll, 42 retracting device, 44 guide rod, 46 rubber thread guide, 46a rubber thread guide, 47 knitting position, 48 weft guide, 50 weft guide, 51 guide rod, 52 warp guide, 52a copy guide, 54 guide rod, 56 58 guide, 60 support, 61 feeder, 62 stockpile, 64 first conveyor, 66 roll, 68 second conveyor. 70 guide rollers, 72 guide rollers, 76 guide rollers, 76 guide knitting positions, 78 deflector, 80 deflection rollers, 82 corn knitting machine, 84 beam, 86 coated faceplate, 88 strike beam, 90 guide beam, 92 guide gap, 94 supply The apparatus of claim 1, wherein the at least one of the first and second guide members includes a first guide member, a second guide member, and a second guide member.

It is an object of the present invention to form a facility of the kind mentioned in all of the above-mentioned drawbacks.

The purpose of the setting can be solved by the features of Claim 1 in the case of all kinds of facilities. By co-locating a crochet knitting machine with a cloth knitting needle, a yarn guide and a rubber yarn guide at the facility of the ribbon knitting machine simultaneously, the crochet knitting of the rubber yarn is performed online in the same facility with the same operation process synchronized with the manufacture of the knitted ribbon . Thus, the rubber seals can be used in an amount and configuration necessary for timely knitting of the knitted ribbon, and the rubber yarn knitted on the crochet yarn is supplied to the ribbon knitting machine with extremely high accuracy, so that the knitted fabric having high quality is manufactured simply and inexpensively . Since as many crotch knitted rubber yarns as necessary for the knitting process can be produced, the crotch knitted rubber yarn can always be used suitably for producing (ribbons) and virtually no waste is produced. The knitted ribbon so produced can have an optimum quality because it can hold the crotch knitted rubber yarn in a non-slidable manner, in particular by once coving the rubber yarn by a specific crochet knitting and adding thereto And can be fixed by the coupling nose. When the knitted fabric ribbon is cut, the rubber yarn does not jump inward and stays at the substantially same position. This facility is particularly simple because the same principle is used for covering and knitting the ribbon, so that the components and drives can be combined in a simple manner.

Advantageous aspects of the facility are described in claims 2 to 11.

In principle, this facility can be configured so that only one knitted ribbon is manufactured, but the conventional embodiment according to claim 2 is advantageous in that there are a plurality of ribbon knitting machines that simultaneously produce a number of knitted ribbons corresponding to one facility.

There are various methods of disposing a needles knitting machine in the ribbon knitting machine according to the present invention. In particular, a simple solution is disclosed in claim 3, wherein a crochet knitting machine for producing a crochet knitted rubber yarn at the same time as the ribbon knitting machine is arranged, whereby the rubber yarn discharged from the crochet knitting machine is fed to the deflecting device of the ribbon knitting machine On the one hand, cocoon-knitted rubber seals on the one hand and knitted ribbons on the other hand can be produced in the same process with tools corresponding to the ribbon knitting machine. Thus, a crochet-knitted rubber yarn and a knitted ribbon can be produced at the same time, and the allocation of the crochet-knitted rubber yarn to the ribbon knitting machine is achieved simply by displacing it around the turning area. Not only the structure of the apparatus is simplified by using the same guide rod as a tool of the crochet knitting machine and the ribbon knitting machine, but also the production of the crochet-knitted rubber yarn in particular can be precisely synchronized with the manufacture of the knitted ribbon. The rubber yarn guide of the cochlear knitting machine may be arranged in a separate guide bar or arranged in a guide bar such as a rubber yarn guide of a ribbon knitting machine according to claim 4, .

As for the discharge of the crotch knitted rubber yarn from the claw knitting machine, a separate discharging device may be provided. Particularly advantageous, however, is the embodiment according to claim 5, whereby the same discharge device is used for the ribbon knitting machine and the needle knitting machine.

Claim 6 describes a further advantageous embodiment of the facility in which a needle knitting machine is arranged on the front end of a ribbon knitting machine. Both devices may be provided with separate drive devices, but preferably both devices have a common drive. The driving device can then be configured so that the needle-like knitting machine and the ribbon knitting machine operate precisely in synchronization to produce the same number of noses per cm. However, in some cases the transmission ratio of the drive to the needle-knitting machine can be varied and thus the needle-knitting can have a nose-per-cm nose different from the fabricated ribbon. Assigning the crochet-knitted rubber yarn to the ribbon knitting machine may be performed by direct coupling, or preferably by the conveying device according to claim 7. [ So that the allocation of the crocheted knitted rubber yarn to the ribbon knitting machine can be precisely controlled and preferably the tension of the rubber yarn can be adjusted separately. The crocheting machine may preferably be arranged above the ribbon knitting machine according to claim 9.

An embodiment of the facility according to claim 10 is particularly advantageous in that a rubber yarn feeder with adjustable ribbon tension is arranged here in the needle knitting machine so that the rubber yarn can be given a tension suitable for the knitting process in the ribbon knitting machine have.

The warp yarns for the ribbon knitting machine and the covering yarns for the needle knitting machine can be supplied by separate yarn feeders. However, the embodiment according to Claim 11 relating to the disposition of the yarn in the loofah is particularly advantageous.

Embodiments of the present invention will now be described in detail with reference to the following drawings.

1 and 2 show a rubber seal 2 which can be composed of a natural or synthetic rubber material. The rubber seals 2 are knitted (knitted) with the crocheted knitting yarn 4. The crocheted knitting yarn 4 forms a nose whose nose 6 includes the rubber seals 2. The rubber yarn 2 knitted with the crotch is indicated as 8 in total.

Fig. 3 shows a cut-away cross-sectional view of the knitted ribbon 10 made of the crochet-knitted rubber yarn 8 of Figs. The cocoon-knitted rubber seals 8 are joined to one another by weft yarns 12 and 14, which are joined to each other by means of warp yarns 18, (12, 14).

The ribbon knitting machine 20 shown in Fig. 4 and the cochlear knitting machine 22 shown in Fig. 5 constitute a part of the facility for manufacturing the knitted ribbon 10 and the crotch-knitted rubber chamber 8, respectively. The ribbon knitting machine 20 and the claw knitting machine 22 are arranged side by side as a pair. There are only one ribbon knitting machine 20 and one knitting machine 22 for the production of a single knitted ribbon 10 or in order to produce a plurality of knitted ribbons at the same time, A suitable number of pairs of the ribbon knitting machine 20 and the waco needle knitting machine 22 are used as described in the example of the cleavage 24 used in the simultaneous manufacture of the yarns 10, 10a, 10b, 10c, May be arranged in parallel. The ribbon knitting machine 20 and the crocheting knitting machine 22 which are arranged in a corresponding pairwise manner by the cleavage 24 respectively are used for the manufacture of the knitwear 16 according to FIGS. And the crotch knitting yarn 4 for knitting the crotch of the rubber yarn 2 can be used.

The ribbon knitting machine 20 shown in Fig. 4 has a conventional configuration and includes a reciprocating beam 26, in which the knitting needle 28 is fixed and the knitting needle is supported on the striking beam 30. [ The striking beam 30 cooperates with the guide beam 32 to form a guiding gap 34 to allow the knitted ribbon 10 to be ejected by the ejection device 36. The discharging device 36 includes two rolls 38 and 40, one of which is driven and the knitted ribbon 10 is discharged through the two rolls and fed to the winding device 42. A rubber yarn guide 46 disposed on one guide bar 44 is used to manufacture the knitted ribbon 10, which allocates a crochet-knitted rubber yarn 8 to a knitting position. The weft yarns guide 48, 50 are likewise arranged by weaving yarns 12, 14 at the knitting position and by the aforementioned warp yarns 18 at that position. For this purpose, a weft guide 52 is used which is fixed to a driven guide rod 54 and a weft yarn 18 coming out of the reed 24 is arranged around the knitting needle 28, Causing the corresponding nose to be struck in the striking beam. To monitor the weft 18, a weft yarn observer 56 is used to scan the weft between the two guides 58. The guide rods 44 for the rubber thread guide 46 and the guide rods 51 for the weft guides 48 and 50 are guided from the support rods 60 to the other side. Corresponding drive arrangements are known from many, for example German application DE-30 34 253 A1 or Swiss application CH-661 305, and therefore in the current range there is no need to discuss this drive further in detail.

The crocheted knitted rubber yarn 8 guided by the ribbon knitting machine 20 is produced in the croquette knitting machine 22 shown in Fig. 5 arranged next to the ribbon knitting machine in the same facility, Numbers are given. In order to produce a crotch-knitted rubber chamber 8, the naked rubber threads 2 are supplied by a supply device 61, which is connected to the first conveyor device 62 from the stockpile container 62, Is delivered to the second conveying device 68, which is also of roll 70, The operation between the two conveying devices 64 and 66 can be adjusted so that the naked rubber threads 2 are supplied with a constant tension. The pre-tensioned rubber yarn is now advanced through the yarn observer 72 and the orientation roll 74 to the crochet knitting position 76 where the rubber yarn guide 46a feeds the rubber yarn to the cloth knitting needles 28a . The rubber thread guide 46a is also disposed in the guide rod 44 stored in the support base 60 as described above. The knitting yarn is already discharged from the cleansing yarn 24 and supplied to the knitting needle 28a by the warp yarn guide 52a, Then form a coating on the naked rubber threads 2. The crotch rubber yarn 8 is discharged by the discharging device 36, which also draws the knitted ribbon 10 from the weaving position. Of course, unlike the knitted ribbon 10 of the winding device 42, the rubber yarn 8 to be knitted with a crochet needle is wound around the knitting yarn 10 by way of a direction changing device 78 having a forward roll (direction change roll) And is supplied to the weaving position 47 of the corresponding ribbon knitting machine 20 as shown in Fig.

Fig. 7 shows an additional facility for the production of a knitted ribbon of the kind shown in Fig. 3, which comprises a ribbon knitting machine 20 of the kind shown in Fig. 4, In facilities 4 and 5, it is not arranged next to the ribbon knitting machine, but here it is connected to the front end of the ribbon knitting machine. The crochet knitting machine 82 of Figure 7 is similar to the ribbon knitting machine 20 and also includes a cover needle 86 disposed in the beam 84, Moving back and forth is guided. A guide beam 90 is disposed in front of the striking beam 88 and forms an evacuation gap 92 for evacuation of the rubber seals 8 cocooned with the striking beam. Or naked rubber threads 2 may also be fed through the feeder 94 and the feeder may be formed similar to that of FIG. The rubber seals 2 are supplied to the crochet knitting position 102 by the rubber thread guides 96 disposed on the guide rods 98 which are moved upward and downward and up and down from the support stand 100. The to-be-copied guide 144 is disposed in the guide rod 106, which inserts the crochet yarn 4 supplied through the corresponding yarn observer 108 into the cloth needle 86 in a known manner . Driving the ribbon knitting machine 20 and the coarse knitting machine 82 has a substantially marked branch 112 for the ribbon knitting machine 20 and a branch 114 for the roughly marked knitting machine 82 A common drive device 110 is used. Whereby the synchronous driving of the ribbon knitting machine 20 and the cochlear knitting machine 82 is ensured. However, in some cases, an adjustment drive not shown in detail in the branch 114 may be arranged to cause the cochlear knitting machine 82 to have a speed different from the driving speed of the ribbon knitting machine 20 so that the unit in the cochlear knitting machine The number of noses per length can be made different from the number of noses per unit length in the ribbon knitting machine. The crocheted knitted rubber yarn 8 produced by the croaker knitting machine 82 is fed to the ribbon knitting machine 20 May be supplied directly or may be fed to the ribbon knitting machine after passing through the two rolls by using a special conveying device 116 with two rolls 118, for example.

This facility has an integrated crochet knitting machine, so crochet knitted rubber seals are manufactured and used in a particularly simple, inexpensive and reliable way.
