Obertshausen - A coarse gauge version of Karl Mayer's five-bar tricot machine, the COP 5 M-EL, offers shoe manufacturers an increasing range of warp knitted design options.
Presented to the wider public at ITMA Asia + CITME 2018 in Asia for the first time, the former COP 5 version has been combined with Karl Mayer’s EL pattern drive in this model to create a tricot machine capable of producing an extensive range of patterns.
Its performance was demonstrated at the in-house show held at Karl Mayer (China) at the same time as the fair and was deemed a great success. The visitors were particularly impressed with a coarse machine gauge which was developed to produce a multifaceted collection for shoe fabrics.
The articles in this collection for use in tough, hardwearing sports and leisure shoes feature stylish, graphic patterns with a contrasting, two-tone coloured effect. Polyester was used to produce the samples: a textured, spin-dyed black yarn was used in ground guide bars, GB 1, GB 2 and GB 3, and a smooth, semi-matt, raw-white version was used in GB 4 and GB 5. The pattern is based on a 1 in/1 out threading arrangement in GB 4 and GB 5. Openings of different sizes can be produced in the ground by varying the lapping.
The wide variety of motifs is produced on the ground pattern during production and protrude clearly from the ground as a result of the spin-dyed yarn. A fully threaded pillar stitch in GB 1 increases the stability of the fabric. At the same time, the underlaps of the other guide bars are protected in order to improve the abrasion resistance.
The patterned fabrics weigh approximately 300 g/m². They are produced in a gauge of E20 and can be worked at an exceptionally high operating speed. The COP 5 M-EL has a maximum speed of 1.200 min-1.
As well as shoes, the COP 5 M-EL in a gauge of E28 can produce sports goods, apparel fabrics and other semi-technical textiles, such as upholstery fabrics, automotive textiles and coating substrates.
The electronic guide bar control, in combination with the five guide bars, gives this all-round machine maximum flexibility.
