Technical Textiles and warp beam frames
Today, the market situation in the textile industry changes faster than ever before. Much of the demand for technical textiles comes from various end-use industries, such as automotive, construction, healthcare, protective cloth, agriculture, sports equipment and sportswear, space applications and environmental protection.

When using warp beam frames for weaving technical fabrics, the following advantages could be achieved.

Flexibility: wide areas of application
Warp beam stands are used for various kinds of applications, ranging from the weaving of fabrics with coarse yarn counts, three-dimensional fabrics, multi-layer fabrics with a different weave-in of the binder yarn and fabric with complex net structures.

Perfect amount and tension electronically controlled
They incorporate electronic controls for feeding the required amount of warp with the requested tension to the weaving machine. During waving process various pick densities and warp tensions can be selected either from the weaving machine or jacquard control.

CREALET is your partner for all current warp feed equipments including creels.

Weaving from bobbin creel

Often tire cord fabric, geosynthetics, fiberglass- and carbon fiber fabric are woven from creels.
When weaving from a creel special attention should be given to the warp delivery unit between creel and weaving machine. The warp delivery unit enables the right amount of warp to be fed to the weaving machine.
The right design of the creel and the warp feed system is very important and therefore deserves highest priority.
Warp feeding from creels to weaving machines can be done in two different ways.
For tape yarn unrolling creels are in use for twist-free supply of the yarn to the weaving machine.
Wherever possible creels with over head draw-off can be used. The creel structure usually requires a large and roomy area behind the weaving machine.
Weaving from creels are done with tensioners, to equalize the warp tension of each individual warp thread.

Warp delivery unit between weaving creel and weaving machine

The warp is pulled off from the creel by a feed roller of the delivery unit and feed according to the needs of the weaving process to the weaving machine.
The feed roller has to be with a suitable roll cover with the corresponding hardness and surface roughness. In some cases, a nip roller has to be added to the feed roller to ensure a warp feeding without slipping. The nip roller can be rubber coated and with a crowned lateral surface.
For high warp density, overlapping of the warp or varying of weave-in the delivery unit can be equipped with several feed rollers. The feeding unit can be equipped with a reed or expansions comb and lease rods to keep the warp in the usual one-to-one pitch.
Additional a warp stop motion or laser stop motion can be mounted which detects any warp breaks arising from the creel. In some cases, a compensation roller is provided to ensure synchronization between the creel and warp delivery unit.

Electronic Warp Let-off

The feed roller in the separate standing delivery unit can be driven with our electronic let-off device or with the integrated let-off of the loom manufacturers. The let-off device ensures that the warp is fed with a precisely controlled tension to the weaving machine.
The warp feeding from the bobbin creel to the weaving machines belongs to our core competence. Together with our partners, we offer you the complete warp feeding. goo.gl/mtxD3e

Airbag - an important lifesaver

The need for security is deeply rooted in man for evolutionary reasons. Airbags and safety belts are considered life-saving safety features in accidents and can be found in all vehicles today. They have been and are continuously developed. Future autonomous driving places entirely new demands on the car occupant protection, as seat positions can be chosen freely in future interior spaces. As a result, new concepts for belts and airbags have to be developed.
To meet the high standards of the automotive industry, the highest quality standards are placed on the airbag fabric. CREALET supports the fabric quality with its selvedge thread let-off devices during the weaving process at the selvedge area.
When weaving dense fabrics it can happen that the selvedge area of the fabric becomes looser than the rest of the fabric. This waviness has a negative effect; particular during the winding and unwinding of the fabric and during the coating process. These disadvantages can be eliminated or at least minimized by feeding the selvedge threads electronically and at a higher tension to the weaving machine with separate spools.

Yarn feeding from creel

Thanks to the cooperation with Eilcher and Meurers Industrietechnik GmbH, CREALET AG is pleased to be able to offer all types of creels in the future. Wherever possible, overhead take-off creels can be used. However unrolling creels are used wherever a twist-free feeding of the yarns has to be guaranteed. Each creel is built according to the customer's specifications. They can be specified for different yarns made out of glass, carbon, metal or basalt.

The yarns are taken off from the creel and are passed through perforated plates with ceramic eyelets at the creel end. Then they pass an expansions comb before being fed via delivery unit to the weaving machine or to the pultrusion unit. The creel used must be able to accommodate the required number of bobbins and to ensure a constant tension over the entire thread sheet.

The feed unit controls the thread tension between the creel and the processing machines and supplies the yarns with the necessary tension to the manufacturing process.

Our application expertise and industry know-how are the key to delivering solutions that meet your needs.

UNWINDING AND WINDING UP

Unwinding and winding up is an often used process in many applications, not only in the textile industry. In the textile industry, the winding of yarns and generated textile surfaces is the main application.

In other industries, however, wires, strands, ropes, cables, hoses, pipes or profiles can be wound up and unwound. Different demands are placed on the tension control depending on the manufacturing process, the physical property of the product and the required web speed.

As a partner to the textile industry, we have a great deal of experience in unwinding and winding up in this field. It will be a pleasure to provide our experience to other industries as well. goo.gl/tLZrdx

WARP FEED DEVELOPMENT

In the past, the fabric was woven on handlooms with fixed warp beams which were locked by a locking device. After the production of a certain fabric length it could be loosened so that more warp could be released.

Here’s a recap of warp feed development, starting in the 18th century up to today’s highly sophisticated electronic warp feed systems. goo.gl/jLzfMu

WINDING DEVICE FOR SURPLUS WARP ENDS /FADAB

It frequently occurs that more warp threads are wound on the warp beam of a weaving machine than are required to weave the intended fabric.

This surplus of warp threads on the warp beam is often intentional in order to ensure that there are enough warp threads available for the fabric.

WINDING-UP OF SURPLUS THREADS

To prevent surplus warp yarn getting entangled with regular warp yarns it is necessary to draw off the yarn from the warp beam. The stand-alone warp take-up makes it possible to draw off and wind up single threads or thread bundles consistently on a take-up reel.

The draw-off tension of the threads or thread bundles can be set steplessly. In the case of a full take-up reel, the material can be easily stripped off the cone by removing the front disk.

During the standstill of the production machine for fault elimination or similar purposes, it is not necessary to disconnect the winding device. Only during longer standstills, e.g. overnight, is this disconnection advisable. A control light shows whether the device is connected or disconnected. This portable warp take-up can be placed behind each narrow and wide weaving machine. goo.gl/CsWBh4
