Whether Basic or Complex – Siemens has Leading-Edge Solutions for Every Fabric Manufacturing Application

Textile Fabric Automation - Main

For advanced system solutions in all conventional textile fabric manufacturing applications, whether knitting, warp-knitting or weaving, including weaving preparation, and subsequent making-up, Siemens provides you with the right automation solutions to fulfill the most complex requirements – starting from circular knitting machines, on which the movement of the knitting cylinder can be conveniently controlled, to extremely time-critical tasks executed on high-performance looms or special looms with up to 50 axes.

The regenerative capability of infeed modules, together with the possibility to exchange energy between axes using the common DC link forms the basis for energy-efficient multi-axis solutions. Compliance with international and local safety requirements is ensured by comprehensive integrated safety technology.

With a solution from Siemens, you can achieve superior performance and flexibility, easy and integrated engineering and worldwide product and application support.

Circular Knitting Machines

Textile Fabric Automation - Circular Knitting

On circular knitting machines, the rotation of the needle cylinder drives the needles through the knitting channels in a vertical up and down movement. The thread that is guided by the eyelet is knitted, and the knitted fabric is taken off to the bottom. On large circular knitting machines, a needle cylinder diameter of 30 inches with a precision of E24, that typically means 24 needles per inch. The fabric take off with subsequent reeling of the fabric tube is usually mechanically led off from the needle cylinder movement.

Solution Example

The SITEX CK (Circular Knitting) control system with piezoelectric bending transducer modules for individual needle selection is tailored for use in jacquard circular knitting machines. This unit combines the following functions in a highly compact design:

  • Pattern preparation as information for bending transducer actuation

  • Process control and visualization

  • Bending transducer actuation

Stitch Bonding and Warp Knitting Machines

Textile Fabric Automation - Stitch Bonding and Warp Knitting Machines

Today's knitwear is expected to meet more complex requirements. Warp knitting machines must produce goods of consistently high quality and still allow rapid product changeovers, so application flexibility depends strongly on the capabilities of control and drive technology.

In a stitch bonding machine with parallel weft insertion, a filling carriage transports a selectable number of weft threads from one side of the machine to the other in synchronization with the machine. Two rakes pick up the threads from the filling carriage and place them into the warps that run synchronously with the machine.

Solution Example

This is a scalable solution which always ensures a smooth interaction of filling carriage, rake and warp. For this, Siemens provides the ideal basis with SIMOTION – thanks to multiple integrated technology blocks on different hardware platforms.

Warping Machines

Textile Fabric Automation - Warping Machine

Here threads are placed in groups on a cone-shaped roller at one end, which continues until the full number of warp threads is reached. Then thread groups are wound together onto the beam (rewound).

Solution Example

The use of SIMOTION D provides several performance benefits because drive components and machine control are combined on a single system.

Sizing Machine

Textile Fabric Automation - Sizing Machine

On these machines warp thread material is supplied from either a warp beam or several thread beams with simultaneous take-off. The warp threads may be pre-wetted and impregnated with sizing liquor in a second immersion bath. The threads then pass through combs that prevent them from sticking together, after which the parallel threads are dried on the sizing machine cylinders and rewound.

To produce superior quality fabric, key functions of a sizing machine guarantee even sizing, perfect thread tension, and the right degree of drying. Siemens ensures these values are optimized and reproducible by means of a uniform automation concept.

Solution Example

In order to ensure homogeneous sizing, perfect thread tension and the right degree of drying, Siemens provides an integrated automation concept with PLC, display technology, drives and switching devices, thus ensuring the optimization and constancy of these values in a reproducible manner.

Looms

Textile Fabric Automation - Looms

Weaving is the most comprehensive area of textile fabric production. Looms perform many individual movements at extremely high speed that must be synchronized with each other. Some of the movements (weaving reed or weft insertion, for example) are led off from the motion of the main shaft via cams. Increasingly, however, electronically-controlled axes are being used, as with warp let-off and fabric take-off. The integration of technological functions with the control platform delivers extremely fast response times, improving the technological performance of looms. A system of function blocks forms the basis for a modular machine automation platform, allowing for a wide variety of combinations.

Solution Example

Based on a controller for textile machines, the web technological movement tasks performed in the hardware and software have been defined for specific users and implemented in the SIMOTION controller platform portal. This is the first block that defines a basic web function and serves as the basis for further automation solutions.
