UV60-W – tool changer and winder; NH2 53 2/130 spaces with bag tape and woven-in drawstring; an application of the bag tape and woven-in drawstring with additional, ink jet process printing using the MÜPRINT MDP3; and the COMEZ ACOTRONIC 8B/600 high-efficiency, electronic crochet knitting machine © Jakob Müller AGJakob Müller AG, a leading specialist in the technology for manufacturing of woven and knitted tapes and webbings, as well as technical textiles, printed narrow fabrics and winding machinery, will exhibit its latest technological solutions at the Techtextil trade fair, which will take place in Frankfurt, from 9-12 May.

COMEZ ACOTRONIC 8B/600 is a high-efficiency, electronic crochet knitting machine that employs compound needles for the production of a wide range of ribbons, technical and medical textiles, both elastic and non-elastic. Compound needles make the machine highly versatile, as in addition to classic synthetic yarns they allow the processing of natural yarns and special fibres in the warp, the manufacturer explains. The machine comes in several gauges, from E10 to E20, has a 600mm working width and is fitted with eight weft bars with electronic control, which can affect weft movements of up to 34 mm.

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 that lend the fabric a lock-stitch character. More complex knit constructions 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 take-off. 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 take-off 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 colour touch screen DATA CONTROL CONTROLLER, which manages 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.

Special embroidery device

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, the company explains.

A new feature of this machine is a special embroidery device which allows to sew weft yarns into a ground fabric. This device requires the use of piercing-compound needles and the yarns that can be processed are really numerous: synthetic and natural yarns, as well as high-performance fibres. For 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.

Narrow fabric weaving systems

The successfully launched NH2 53 narrow fabric loom is now available on the market in the widened and strengthened NH2 53 2/130 version, which will be exhibited at the Techtextil 2017. It has a reed width of 130 mm, enlarged shed and in-creased heald shaft lifting power.

The electronically controlled NH2 53 2/130 narrow fabric loom, which offers virtually unlimited repeat lengths, will be shown producing a bag tape with woven-in drawstring. As a result of the electronic shed formation possessing patterning possibilities employing up to sixteen electronically controlled heald shafts, a variety of bags in differing sizes can be produced on every machine space.
