DE2540939A1 - Loose weave fixing equipment - takes fabric from loom for saturation with bonding fluid followed by two drying stages - Google Patents

Abstract

An apparatus is claimed to bond and stabilise loosely-woven fabrics, such as for mosquito netting, filters, basic floor coverings or tapestry work. As the fabric emerges from the loom it is saturated by a bonding fluid and then subjected to contact-free drying by an infra-red heater with a final drying stage by applying contact heat. The system ensures that the fabric passes directly from the loom to the fixing stage so that the fabric structure is not distorted by winding and transportation to a remote vat processing stage.

Description

Elebe and fishing device for securing loosely pitched ones to slide Tissues.

For a number of special purposes, fabrics are needed that are special are knocked loosely, i.e. on 1 cm, e.g. only 3, 4 or 5 so. Shots registered.

These thieves with large, empty boxes are needed, for example For noskito nets, filters, base fabrics for floor coverings, tapestry embroidery, etc.

Since mostly smooth threads made of synthetic fiber material (filaments ) are used, there is a risk that the Eett and weft threads will be displaced against one another become very big. However, no of the above purposes measured those on the loom The geometric tissue structures formed must be preserved in full.

In practice, one usually helps oneself in such a way that the fabric is in the loom as usual, it is then wound up in the equipment on a poulard with a mostly soaked in watery adhesive liquid and then on a hot flue or tensioning frame With this, the intersection points of the fabric are glued and solidified (fixed).

Apart from that these processes are from the machine investment is very expensive, there is also the risk of an unavoidable thread displacement during the entire transport and treatment phase. When winding the loose beaten fabric in the weaving machine, when cutting and removing the fabric tree, during transport within the weaving mill and equipment as well as during the actual treatment processes, the retention of the thread layer originally produced in the loom is practical not possible.

In order to eliminate the aforementioned disadvantages, according to the invention (cf. Fig. 1) the process of sliding fastening is transferred to the loom and developed the following device for this purpose: The goods produced on the weaving machine 1 2 is not wound up directly in the loom, but on an already known so. taulen-or. Ascending batch winder 3 rolled up. Between these two aggregates 1 and 5 the actual Elebe and Pixiereinrichtung is now interposed, from the Isprignier- (Pflatsch-) device 4, the Weber stand platform 5, dei Pre-dryer 6 with the separate pre-dryer 7, the suction device 8th , the post-drying chamber 9 with the drying drum 10 and the outlet slot 11 consists.

The individual treatment steps that the tissue 2 goes through begin with the impregnation device 4, where by a liquor trough with a sponge rubber roller, the tissue is soaked with the mostly watery adhesive liquid. The inflow the liquor can be fed via a follow-up tank with an interposed float box and vibration valve, take place automatically. This allows the liquor height in the liquor trough set and thus the immersion depth of the sponge rubber roller can be determined If the liquor level is high, there will be a lot of adhesive liquid and if the level is low, there will be less applied to the fabric.

After this lip impregnation process, the fabric passes through the platform 5, so that the adhesive liquid has enough time to evenly settle on the fabric to distribute and soak it. The goods then enter the Pre-drying chamber 7 with suction device 8 including connected suction fan 12 via a infrared dryer 6 with a refector or a hot air drying field, the non-contact drying of the adhesive is initiated. A scorching hazard and odor nuisance is avoided by the suction device 8 and 12. If the weaving machine suddenly comes to a standstill, the infra @ ot emitter, which reacts much too slowly, is turned off not switched off, but pivoted away from the goods by approx. 900 while the suction device This means that heat damage to the goods is definitely excluded. When the loom is switched on again, the emitter is swiveled back 6 on the fabric, the pre-drying process suddenly being full again Intensity is continued. In order to achieve complete drying, the goods run in the post-drying chamber 9 on a drying drum 10 or through a hot air drying zone, where the residual drying is carried out without, because of the only slight residual fire, a sticking or encrustation on the whale can occur.

As a result of the subdivision into non-contact pre- and post-closing Contact post-drying is particularly reliable and at the same time economical Working method guaranteed.

The pre- and post-drying chambers are designed as a structural unit and are both by means of connecting locks, through the common Suction device 8 and 12 applied.

After the fabric is completely dry, the points of intersection are the Threads glued together in Eett and weft direction, so that they move during the course the subsequent work processes can no longer occur.

A large dock is wound on the drum winder 3 (up to 2000 mm ß) which, consisting of one piece, is now a particularly economical one and quality-assuring further processing.

Claims (8)

Claims 1) Gluing and fixing device for securing loose pieces to slide Woven, characterized in that the goods are directly after the weaving process with a Soaked adhesive liquid; then an active section runs through - which runs simultaneously is designed as a Weber stand pedestal and then through a contactless drying process Pre-dried by means of an infrared heater and a subsequent contact heating (Heating drum) to be post-dried or fully dried. 2) gluing and fixing device according to claim 1), characterized in that that the contactless pre-drying and post-drying process, which is divided into 2 stages, takes place the infrared drying and the downstream contact drying, by a hot air dryer -nung is replaced. ->) Gluing and fixing device according to claim} and 2), characterized characterized in that-the impregnation device is equipped with a sponge roller is what the electrical fluid - depending on the adjustable immersion depth in the fleet - applies in larger or smaller quantities ("patting") 4) Gluing and fixing device according to claim 1) to 3), characterized in that the Weber stand platform as a linger or effective distance is used. 5) gluing and fixing device according to claim 1) to 4), thereby ekennzeinet, that the infrared emitter in the event of sudden machine stoppages, because of its sluggish heating characteristic switched off, but swiveled away from the tissue or shielded and swiveled back when restarting, or. from the shield is released. 6) Elebe and fixing device according to claim 1) to 5), characterized thereby, that the post-drying is preferably carried out by contact drying, via a heated drum Alternatively, however, they can also be carried out using hot air or infrared radiation can. 7) Elebe- and fixing device according to claim 1) to 6), characterized in that the pre-drying and post-drying chambers are equipped with a common suction device to prevent scorching damage to the tissue and odor nuisance from the drying adhesive liquid. 8) living and fixing device according to claim 1) to 7), characterized thereby, that pre-dryer, post-dryer and suction device combined in one unit are.
