On occasion of the most important exhibition of the textile market, Comez show its innovative 800 ACO/EL, a crochet knitting machine with electronically controlled yarn tension and stitch density regulation, and the DNB/EL-32-12B, an electronically controlled warp knitting machine with double needle bed for the production of technical and garment textiles. These two machines are visible during ITMA 2019, from 20th al 26th June, at Hall 4.0 Stand A107 which Comez shared with all the Jakob Müller group.
The 800 ACO/EL machine, recommend for the production of elastic as and rigid fabrics and tapes, is ideal for products with lock-stitch structure especially in technical fields. The machine offers a wide range of product options and applications such as:
- Medical and orhopaedic textiles (body belts, gauzes and bandages)
- Astrakhan with close loop
- Articles for house cleaning
- Furnishing ribbons and tapes
- Sportswear ribbons
The compound needle makes the machine highly versatile as it allows the processing in the warp – in addition to classic synthetic yarns (polyester, polyamide, polypropylene) – of natural yarns (cotton, wool) and special fibres (aramid, fibreglass).
It is equipped with 8 weft bars controlled by chain links, composed of links presenting an involute profile, allowing weft movements of up to 30 mm and allowing high operating speeds and low noise emission levels. As an alternative, two bars can be driven by the weft device for weft movements of up to 50 mm.
The electronic operating system allows to choose different stitch density values on one single product as well as different values for weft feeding. The yarn tensioning and the stitch density are defined by our exclusive COMEZ DRAW 3 or SYSTEM.WIN PC textile software. Datas are transferred from a PC to the controller on the machine by means of an USB key.
Finally the 800 ACO/EL can be defined as an hybrid control machine which merges the economic advantages of a mechanical structure to the wide possibilities of product personalisation given by the electronic component.
The second machine shown at ITMA 2019 is the new DNB/EL-32-12B, an evolution of the Comez electronically controlled warp knitting machine with double needle bed. This machine offers many benefits to the users, such as a higher efficiency, reduced working width allowing fast article changeovers for small and long runs and a compact design with all integrated devices including the beam support.
For this reasons DNB/EL-32-12B suitable for the production of many different articles, such as:
- Technical textiles such as nettings, geo textiles and industrial fabrics
- Medical textiles such as nettings, bandages, dressings and disposable pants
- Shoe uppers (3D fabrics)
- Garment textiles
The machine is available now with 12 guide bars electronically controlled in order to develop advanced technical fabrics. It is also applicable now a long shift electronic device that allows one or two bars to place a weft yarn with a maximum displacement of 560 mm. This feature makes more reinforced fabrics and allows to create technical textiles with continuous weft insertion likes conductive yarns.
Any type of yarn can be processed according to the machine gauge: natural fibre yarns such as wool and cotton; synthetic yarns; special yarns such as aramid, glass fibre yarns, metallic yarns; high tenacity PP and PES yarns, monofilament yarns, etc.
COMEZ DNB/EL-32-12B is equipped with the DATA CONTROL CONTROLLER, governing the latest generation of actuators providing excellent dynamic performance and high positioning precision.
