MACH2X

MACH2X

HIGHLY EFFICIENT ULTRAFINE GAUGE WHOLEGARMENT PRODUCTION.

SHIMA SEIKI's MACH2X is a WHOLEGARMENT specialty machine that features 4 needlebeds and SHIMA SEIKI’s original SlideNeedle. It can knit beautifully shaped, high-quality WHOLEGARMENT products which conform to the body for improved comfort and a more elegant silhouette. As the “MACH” name suggests, improvements in speed and productivity are dramatic. MACH2X achieves a maximum knitting speed of 1.6 meters per second. The R2CARRIAGE system furthermore permits quicker carriage returns for higher efficiency per knitted course. Split Stitch technique also allows efficient knitting by eliminating empty courses. Additionally, MACH2X123/153 features 18L gauge capability whereby a special large-hook version of the SlideNeedle is used for knitting 15-gauge fabrics at 18-gauge needle pitch for very high productivity when knitting ultrafine gauge garments. The tighter needle pitch also allows for a tighter fabric especially for ribs, contributing to higher-quality WHOLEGARMENT items. Additional improvements include a control unit that is built-in to the machine for simplified shipping and installation, easier maintenance, and more efficient use of space. A USB memory interface and a backup power supply are standard. MACH2X also features a lower overall height for improved access to top tension units. Dramatic improvements in both quality and productivity make MACH2X an ideal machine for high-quality WHOLEGARMENT production.

Rapid Response R2CARRIAGE System

The R2CARRIAGE (R2=Rapid Response) System features an advanced carriage mechanism combined with improved software programming that achieves quicker carriage returns after each course. For a given knitting width, a larger and heavier carriage requires more space (B) at each end of the machine to decelerate, return and accelerate back up to speed, so the actual portion where the carriage runs at full speed (A) becomes very limited. With a compact, lightweight carriage, less space is required for the carriage to make returns, allowing more area for the carriage to run at full speed. This allows faster knitting per course, resulting in higher productivity.

i-DSCS+DTC

i-DSCS

Standard on MACH2X is i-DSCS+DTC Digital Stitch Control System "with Intelligence" and Dynamic Tension Control. i-DSCS+DTC carries over the benefits of DSCS while achieving the ultimate performance in digital knitting. Whereas DSCS is a passive system that mechanically limits yarn-feed, i-DSCS+DTC has the capability to actively control yarn-feed in both feed and retrieval directions as necessary, through variable electronic control of yarn tension. This results in even higher quality and greater productivity using a wider variety of yarns, including high-speed knitting of challenging yarns such as fancy yarns, stretch yarns, slub yarns and delicate cashmeres. Precise electronic control means i-DSCS+DTC provides consistent quality among different machines, production batches and repeat orders, and is crucial to the precision knitting required in WHOLEGARMENT production.

4-Bed Configuration

4-Bed Configuration

MACH2X features SlideNeedles which are mounted on 4 needle beds, in effect attaching 2 extra beds on top of a conventional V-bed. This setup allows unprecedented capabilities in knit and transfer, significantly expanding design and patterning capability in WHOLEGARMENT production. As a result, MACH2X is the only machine in the world which is capable of producing fine gauge WHOLEGARMENT knitwear with rib structures.

The Original SlideNeedle

In its pursuit for ideal WHOLEGARMENT production, SHIMA SEIKI has reinvented the most basic element of knitting—the needle. The new SlideNeedle is the result of a thorough re-evaluation of the 150-year old design of the conventional latch needle, and offers knitting possibilities never imagined before. A flexible two-piece slider mechanism splits and extends beyond the needle hook for increased potential especially in complex transfers. Using the slider mechanism for transfer effectively eliminates the transfer clip, allowing the needle to be mounted in the center of the needle groove. SlideNeedle thereby achieves perfectly symmetrical loop formation for knitting the highest possible quality fabrics.

Pulldown Device

Pulldown Device

MACH2X ’s new computer-controlled takedown system consists of front and rear panels over which tiny pins are distributed for separately controlling takedown tension for the front and back when knitting WHOLEGARMENT knitwear. In addition, each panel is separated into 1.5-inch sections which can be individually controlled for specific tension control across the entire width of the garment. This precise control over takedown tension permits three-dimensional shaping of WHOLEGARMENT items—for example, by allowing shoulder lines for set-in sleeves to be positioned over the shoulder toward the back—resulting in a more dimensionally accurate garment which conforms better to the shape of the torso.

Air Splicer (optional)

Air Splicer (optional)

Unlike conventional knotter systems which mechanically tie together yarn ends, the Air Splicer cuts then twists together yarns with a burst of pressurized air with split-second accuracy. Working in precise coordination with our i-DSCS+DTC Digital Stitch Control System "with Intelligence" and Dynamic Tension Control, the Air Splicer is able to time each splice so that perfect color changes can occur exactly as programmed. With the Air Splicer, high-quality multi-color WHOLEGARMENT knitwear can be produced easily and with beautiful results.
