LÜNEBURG, Germany — March 15, 2019 — eurolaser GmbH, a manufacturer of carbon dioxide laser cutting systems, presents the latest technology in the field of textile cutting at the Texprocess fair in Frankfurt. The focus is on automation for Industry 4.0. This year, the cutting of textiles on the L-1200 and 3XL-3200 systems will be demonstrated live on-site. The emphases of the exhibition will be on the automatic feeding of textiles from the roll, on the cutting of printed textiles including the camera and QR code recognition as well as on the labelling of the individual pieces in a single operation

eurolaser has revolutionized large-format textile processing with the laser cutting machine 3XL-3200 (working surface: 3.210 mm x 3.200 mm). However, size alone is not the key to success. With the Conveyor system, eurolaser delivers a market proven solution especially for the automated processing of textiles. For this purpose, a special table concept is used. It consists of a stainless steel rod mesh and is particularly suitable for thin and flexible materials, such as textiles. It serves as a material carrier for the processing and at the same time as a transport element for the conveyor system. The material is fed via an automatic feeding unit. The automatic edge control of the feeding unit ensures a constant material alignment and thus, continuously precise high quality cuts – meter by meter. Due to the automated material feed while relieving the operator, the load factor increases. With sensors, the unwinding unit is controlled so that the previously defined position on the work surface is exactly maintained. This ensures optimal material utilisation and less material waste.

The material is fed directly from the roll by the conveyor belt to the laser system and processed there. The stress-free material feed does not cause any fabric distortion and the non-contact processing by the laser leads to excellent results. For synthetic textiles, a slight melt seam (cut & seal process) is created at the cut edge, which prevents fraying and saves additional work steps such as linking. During the laser processing, the already cut material can be removed from the laser system via the unloading table. The table extension has the additional advantage of enabling the material to be removed from three sides, which boosts flexibility in the production process even further. If necessary, a winding unit can be added to the unloading table. The unit ensures even winding of already processed textiles. For optimal results, retaining cutting bridges may have to be worked into the cutting contours in order to keep the cutting results in combination with the cutting edge material. The winding unit is positioned at the end of the cutting process thus, enabling full automation of the entire process.

Next to the laser, eurolaser systems can be equipped with additional modules such as a label module for applying labels and an ink-printer module for printing. For example, a direct labelling eases the assignment of individual textile blanks for downstream production steps. On the L-1200, the advantages of the combination of laser and labelling modules are shown by the example of cutting all the individual parts of a card case made from two-ply cordura fabric. Alongside the advantages of large-format, automated textile processing by laser are demonstrated on the 3XL-3200.

Be inspired by the innovative laser cutting technology and visit us at the Texprocess Hall 4.0, stand D91. We would be pleased to welcome you at our stand.

OBERTSHAUSEN, Germany — March 14, 2019 — KARL MAYER is showcasing warp-knitted textiles having an exceptional level of performance in hall 3.0/E 18 at Techtextil 2019 in Frankfurt. On show will be products with integrated electrical conductivity and shaping characteristics from the new TEXTILE MAKERSPACE platform, an extremely efficient textile solution for protecting buildings, and a completely new generation of warp-knitted spacer textiles. Karl Mayer is also inviting people to attend an in-house show, to be held at the same time as the fair, at its headquarters in nearby Obertshausen. This event is easily accessible by bus transfer and will be premiering a new nonwovens machine for the visitors. Karl Mayer is also a trendsetter in the field of digitization. This manufacturer has grouped all its digital solutions under the KM.ON brand, and will also be showcasing this system on its stand at the Techtextil.

RAPID TEXTILE– the quick way to new solutions

Textiles with an excellent performance and lower manufacturing costs can be produced by combining the possibilities of additive production with warp knitting technology. Examples of this include warp knits functionalised by 3D printing and these are being presented at Techtextil.

Karl Mayer has grouped together all its activities relating to the use of new technologies and innovative products under the concept of RAPID TEXTILE. They form part of the TEXTILE MAKERSPACE system, a platform that offers the space to try things out, develop new products and think outside the box.

TEXTILE CIRCUIT – the quick way to electrifying designs

Electrically conductive textiles are a hot topic at the moment and can be produced in a variety of different ways. The easiest method is to directly incorporate conductive yarns during fabric production on the machine.

TEXTILE CIRCUIT, another element of TEXTILE MAKERSPACE, shows the potential of warp knitting here. Conductive zones offering maximum flexibility in terms of geometry, dimensions and location can be produced on Karl Mayer’s multibar raschel machines. Examples include inductive charging stations and the remote control of robots, and these are being demonstrated at Techtextil.

New solutions for patterns with plastic effects

Double-bar raschel machines have become firmly established in the production of warp-knitted spacer textiles featuring a variety of designs. A new model is now enabling completely new designs to be produced, i.e. warp-knitted textiles with decorative, relief surfaces. Instead of the spacer layer, three-dimensional design elements are worked on the upper and lower sides. The designs can be shaped and positioned almost without any restrictions, and can be combined with openwork designs. This is opening up a new dimension in near-net-shaped production in particular.

Security panels made from weft-inserted warp-knitted textiles — efficient cut protection for buildings and vehicles

Burglars frequently use chainsaws and drills during attempted break-ins, but they can be stopped effectively by a new type of patented security panel with weft-inserted warp-knitted textiles in the core. On contact with the cut-resistant textiles, the rotating tools quickly release large amounts of fibres from the material. These become entangled and the tool is stopped. The highly effective security panels are also very light and can be applied very easily to e.g. security doors, armoured vehicles, vaults and cash machines.

New raschel machine for web bonding – more opportunities on the nonwovens market

A model in the new RACOP-NW series will be demonstrated at an in-house show in Obertshausen at the same time as Techtextil. This efficient nonwovens machine produces stitch-bonded nonwovens from feed webs, a technology that offers many advantages. This process produces nonwovens having textile characteristics, such as elasticity and voluminosity, which is not the case when using chemical bonding agents. Furthermore, much less energy is consumed compared to thermal processes. In addition to these general advantages, the new RACOP-NW model also offers an exceptional cost:benefit ratio. It is also extremely flexible and can, therefore, be used in a variety of applications. A RACOP-NW, 160″, gauge E 14, is producing a textile for the application area heating textiles at the in-house show.
