No more vertical line

In traditional single jersey machines the stitch is constructed with the help of the sinkers. This process may cause one of the most frequent defects in knitted fabrics: vertical lines. The sinkers are parts that move horizontally and vertically and the stitch is formed on them. In the DS3.0 machine the stitch is formed in a stationary point of the cylinder and consequently we obtain a superior uniformity of the stitch and a total absence of vertical lines.

No more elastane misplating defects

In the traditional machines with the sinkers, in most cases in order to find the perfect position of the cotton, viscose yarn relative to the elastane yarn one has to find the optimal position of the sinker ring and the yarn guide.In the DS3.0 (Double Sinkers) machine the point of stitch formation is well designed and entirely stationary. This feature coupled with the appropriate yarn guide guarantees a perfect stability in the position of the cotton and the elastane yarns avoiding thus misplating.

In such a case the fabric control operation becomes redundant.

No more fabric peeling

Special reference is made to the very fine gauge traditional machine with sinkers using microfiber yarns, where the yarns and the produced fabrics rub on the sinkers that slide radially creating friction that damages the fabric and ultimately causes peeling. In the DS3.0 machine this does not happen because the fabric is formed in a stationary, non moving point.

Ideal solution for very fine gauges

Fine gauges, 40-44, have become popular in the last years especially for the production of stretch fabrics for underwear. The difficulty in the production of these fabrics and the extreme care in handling of the yarns, especially microfibres, have demonstrated the limits of the traditional machines with sinkers in the fabric formation because of the vertical lines.

Furthermore, the problem of deterioration of those parts of the needles that come into contact with the sinkers also arises (grinding of the latch spoons).  

This does not happen with the DS3.0 machine since it does not have sinkers and therefore it does not create either the vertical lines problem or the needle decay.

 High productivity

The DS3.0 32" Diam. 40 gg with 96 feeds can run normally at a speed of 30 rpm Using polyamide 44/34 dtex with elastane yarn 22 dtex it can    produce 280 kgs in 24 hours.

With this improvement in production capacity the SL 2.3 moves to first place production wise.

Solution of the problem of picking up the dropped-off fabric

After many years of studying and experimenting to find a solution to the problem of picking up the dropped-off fabric we have designed a system of picking up the fabric, in case it drops off, that simplifies the whole operation and actually is equal to that effected in a traditional machine with sinkers.

This result was obtained by installing special elements and a semi automatic system that moves the yarn guides in an optimal position for the opening of the needle latches. Thus, the picking up of the dropped-off fabric becomes easy and quick. "

No more cleaning and maintenance operations needed

Trials by our customers in the last few years have shown that with the DS3.0 machine during 8/9 months of production, with a daily production of 500 kgs of fabric which means a total of 120.000-150.000 kgs, the machine needs no maintenance nor cleaning in the area of the stitch formation.

This guarantees a high quality fabric and money saving in addition to the total absence of problems.

Easy replacement of parts worn down by yarns

This system that can replace easily the deteriorated inserts that form the knock over area as though they were normal sinkers.

We believe this to be an efficient solution to the problem.

Great energy saving

The DS3.0 machine has many movable elements that work in the external  ring having a body that is 50% of the body of a sinker. The DS3.0 machine has as many movable elements as the number of sinkers in a traditional machine working in the external ring but their mass is 50% of that of the sinker.

Consequently the energy saving is estimated at 10%-15% compared to a machine with sinkers working under the same conditions.
