Italian warp knitting and crochet machine manufacturer Comez will be showing its latest innovations at ITMA 2015 on the stand of parent company Jakob Müller AG, Hall No. 3; Stand No. D110.

Founded in Switzerland in 1887, Jakob Müller AG is the world’s leading company with regard to technology for the manufacture of woven and knitted tapes and webbing, woven ropes, woven labels and technical textiles, printed narrow fabrics, dyeing, make-up and winding machinery. The Müller programme covers all the needs of the ribbons and narrow fabrics industry from individual yarn processing up to the finished, made-up product.

Comez Acotronic 8B/600 electronic crochet machine with compound needles

On show from Comez will be the company’s Acotronic 8B/600 – an electronic crochet knitting machine with compound needles. The Comez Acotronic 8B/600, is an electronic crochet knitting machine that employs compound needles for the production of a wide range of ribbons, lace, technical and medical textiles, both elastic and non-elastic. According to the company, compound needles make the machine highly versatile, as in addition to classic synthetic yarns (polyester, polyamide) they allow the processing of natural yarns (cotton, wool) and special fibres (Kevlar, fibre glass, carbon) in the warp.

The machine comes in several gauges, from 10 to 20 needles per inch, has a 600mm working width and is fitted with eight weft bars with electronic control, which can effect weft movements of up to 34 mm. The mechanical control of the triple-lever weft device is utilised for continual weft movements (without pattern) of up to 50mm and the control of the heddle bar for elastic threads. This enables users to disconnect up to three bars from the electronic control and operate them by means of the weft device levers.

A supplementary warp tube bar with electronic drive (BPO/STR-600) can be supplied on request. This has an electronic drive that allows the creation of various knit constructions in the warp (open lock-stitch, closed lock-stitch, etc.) that lend the fabric a lock-stitch character.

More complex knit constructions (e.g. double lock-stitch) are also possible using the BPO/STR-600 together with the standard warp bar, which is driven by special cams (TRICOT/S). The machine is supplied with one feeder for elastic threads, one feeder for non-elastic threads, one feeder for warp threads and electronically controlled finished product takedown. On request, additional feeders fitted with electronic controls can be mounted on the machine for elastic or non-elastic threads.

The electronic drive applied to the feeders and the finished product takedown provides the possibility of varying stitch density values (stitches/cm) in a single product, as well as different values for weft/warp feeding and elasticity.

The COMEZ ACOTRONIC 8B/600 is fitted with the DATA CONTROL CONTROLLER, which man-ages all essential machine functions, monitors production data and enables the realisation of lengthy pattern repeats. Indeed, the number of lines available for each pattern is virtually unlimited. Exclusive PC textile software completes the patterning and programming.

The machine can be fitted with the electronic, DLT/EL long throw device that can control up to three weft bars and allows the production of fabrics with long weft movement of up to the full working width along with the possibility of single pick control. In order to guarantee constant warp feeding tension, an electronically driven positive feeder can be used, which allows the setting of the quantity and tension of the yarn to be fed to the needles.

In the case of warp yarns in particular, it is possible to use beams that require little space and ensure the starting steadiness of the yarns. Beam supports are available for positioning on the machine base or at a distance.

Comez Testronic 1600/EL – electronic crochet knitting machine for the production of fabrics for outerwear and technical applications

The Comez Testronic 1600/EL is an electronic crochet knitting machine for the production of a wide range of fabrics for outerwear, accessories (e.g. scarves and shawls) and fabrics for technical applications.

According to Comez, the unsurpassed versatility of this machine creates enormous long pattern repeat capacity using yarns of all types and counts. The machine is thus able to produce bouclé, plain and openwork knitted fabrics and offer dimensional stability, elasticity and an output rate that cannot be matched using other knitting machines.

The machine comes in gauges of 5, 10 and 15 needles per inch has a 1620mm working width and can employ either latch or bearded needles.

It is fitted with seven weft bars for electronic control for movements of up to a maximum of 150mm, and with a warp heddle bar with electronic drive, for movements of up to a maximum of 30 mm.

The machine can be equipped with the electronic DLT/EL long throw device, which can control up to three weft bars to produce fabrics with long weft movement of up to 1 metre.

It features progressive and gradual electronic control and can perform weft movements of up to 1 metre, with "1:1" needle spacing. Numerous fabric types can be produced with the DLT/EL device such as baffle nets for making big bags, wide fringes with single weft and a number of other types of fabrics.

The takedown and eventual feeders are electronically controlled, allowing for variations in stitch density and yarn feed to create special effects.

In order to guarantee constant feeding tension, electronically driven shafts positioned on a beam-carrier are used to control the rotation speed of the beams, thus allowing the setting of the tension of the warp and weft ground yarns.

The COMEZ TESTRONIC 1600/EL is fitted with the DATA CONTROL CONTROLLER, which man-ages all essential machine functions, monitors production data and enables the realisation of lengthy pattern repeats. Indeed, the number of lines available for each pattern is virtually unlimited. In addition, exclusive PC textile software carries out patterning and programming.
