Computerized Flat Knitting Machine



The Global Standard, Now with the Option for Intarsia

As SHIMA SEIKI's newest generation of standard workhorse machines, the new SIR122 is the new global standard for shaped knitting, having inherited the know-how and experience accumulated over the years as the leading manufacturer of computerized flat knitting machines. Productivity is increased with a maximum knitting speed of 1.4 meters per second, combined with the R2CARRIAGE System that improves efficiency in each course through quicker carriage returns. It also carries over proven SHIMA SEIKI technology such as our renowned Digital Stitch Control System (DSCS), spring-loaded Full-Sinker System, Stitch Presser, Takedown Comb and Yarn Gripper and Cutter which is now equipped with a new lint remover for reduced maintenance. Equipped with the 21-intarsia carrier option, SIR allows great freedom in knitting intarsia garments, aided by tremendously capable design system software. Production leadtimes can be dramatically reduced using the Automatic Intarsia Carrier Setting software featured on our SDS-ONE APEX3 apparel design system. Made-in-Japan quality, reliability, productivity, user-friendliness and cost-performance combine to satisfy the high expectations of the world's fashion industry.

Productivity / Reliability

The World’s First Digital Stitch Device


Considered one of the most significant breakthroughs in modern-day knitting, SHIMA SEIKI's patented Digital Stitch Control System (DSCS) continuously adjusts yarn feed and tension to yield loop consistency with tolerance to within a remarkable ±1%. The result is quality control capability that is virtually impossible with conventional analog systems. In addition to being an essential element in quality shaping and integral garment production, DSCS allows consistency among different batches and repeat orders. DSCS is the only proven digital system field-tested and market-proven in the industry for 30 years. No other manufacturer can claim this kind of experience or level of refinement.

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.




The SV variant of SIR122 offers WideGauge capability that allows a variety of gauges to be knit on a single machine. This allows the freedom to handle changing seasons and shifting trends without investing in a machine for every gauge or resorting to the complex, time-consuming task of gauge conversion.

Intarsia Knitting (optional)

Intarsia Knitting (optional)

SIR122 machines feature the capacity for up to 21 intarsia carriers. The new intarsia carriers are more compact, fitting more carriers and thus allowing more color changes within a given knitting width. SIR122 also features light and rigid aluminum yarn carrier rails that form an arch-shape. This creates equal distance and angle to the needlebed for all yarn carriers, permitting a straight yarn carrier design which in turn contributes to smooth and stable operation.


Spring-Type Full Sinker

Spring-Type Sinker System

Spring-type sinkers operate full-time regardless of carriage position, and provide gentle holddown movement, realizing significant improvement in quality and texture for complicated three-dimensional fabrics.

Stitch Presser

Stitch Presser

The patented stitch presser system features a special motor-driven system which allows the pressers to carry out individual on/off adjustments in both knit and transfer, in either course direction. These pressers are able to hold down fabric gently for improved consistency and control, contributing significantly to quality shaping.

Other Features

Yarn Gripper and Cutter

Our unique yarn gripper and cutter system consists of two yarn grippers and one yarn cutter that work in precise coordination with each other. Since the gripper and cutter are separate units, they can be independently activated to delay cutting while holding, or perform holding alone.

A User-Friendlier Knitting Machine

A User-Friendlier Knitting Machine

Space efficiency is improved during installation by integrating the fabric collection tray within the machine frame. The network connector is repositioned on the side of the machine for easier access while transferring comprehensive data using Shima KnitPLM. The USB interface is also positioned directly below the control monitor for improved access in data exchange. For those moments when power suddenly becomes unavailable, a backup power supply allows work to resume after power failures. This offers peace of mind that an entire garment will not be lost due to blackouts.
