Itema Silver 501

Rapier Weaving Machine Itema

Itema’s new rapier weaving machine – Silver 501 is the strategic evolution of the highly successful Silver HS model. Based on the same footprint and complete with a new electronic platform, the Silver 501 is specifically engineered to handle demanding styles or heavy weight denim at the highest production speeds with superior quality. Key

developments of the drive and transfer systems provide a more robust machine that insures a consistent, high speed transfer at the lowest vibration pattern. The ease of use, maintenance and operation synergies remain to provide a transition free integration for weavers and technicians alike. Best suited in a continuous operation, the new Silver 501 is the workhorse of Itema.

A High Performance Weaving Machine

Consistent Performance

As with previous Silver models, the Silver 501 uses the distinguished Propeller Drive formovement of the rapier. With the market demanding higher speeds and complex styling, the consistent and smooth stroke provided by the propeller drive is more essentialthan ever before. Through new manufacturing methods and increasing metal hardness, our Engineerswere able to improve drive capacity, yieldinghigher machine speeds while minimizing vibration. Even under the most difficult textile conditions, 700 picks per minute can beachieved with good efficiency and fabric quality.

Low Vibration Pattern

The Silver 501 presents a very low vibrationpattern. In addition to a solid drive, the machine is engineered with extensive control of the moving masses to reduce vibration. As such, the Silver

501 easily handles the demands of heavy-weight styling while reducing cost through less maintenance and spare parts. Sound Structure

And the Silver 501 Engineers didn’t stop with the drive & machine frame; they completed the effort with a re-designed  slay and complete new back rest module. The new slay design opens the door to speed & versatility. The new back rest “module” compliments the enhancements by reducingwarp tension and promotinga clean shed break with each pick thrown.

New Textile Solutions

New SK Transfer

The new SK TransferSystem is engineered for high speed and versatility. While providingfor a wide array of weftyarns, the SK Systemis the most advanced transfer system on the market today. With an ultra-light, ceramic coated, one piece design, the SK System is engineered for high speed and less wear.

Improved Textile Efficiency

The insertion rapier, with its tip close to the reed eliminates warp floats and increases insertionefficiency. The receiving rapier features a unique and patented opening system based on a permanent magnet in the gripper. In addition, the fine-tuned finger stroke of the new weft selectorallows gentle movement of the weft yarn eliminating interference between selected wefts and resting weft.

Improved EK Transfer

The improved version of the well known EK Transfer System offers greater durability and covers the whole weaving range.

Free Transfer System FTS

For filament & technicalweavers, the Silver 501 offers a race board configuration with noguiding elements in the shed for optimum weaving of delicate, multifilament, low-twist weft yarn ranging from 10 den monofilament to 1500 dtex high tenacity, PES double pick insertion.

New Functionalities

The innovative concept of the Silver 501 allows the user to set the shed crossing point through the touch screen. The new electronic platform makes it possible to set the synchronization between weaving machine and dobby withoutmechanical intervention of the technician. Clearly this makes the job easier, while improving the textile performance of the Silver 501.

The new motorized selvedge & leno device and the “Rotocut” Rotary Cutter are the latest in technology. The programmable weft cutter, along with other options,allows the user to configure the optimum textile settings specific to unique yarns and weaves.

 New Electronic Platform

Full Color Touch Screen

The Silver501 arrives with the latest intechnology offering a new electronic platformwhere the full color, touch screen acts as the user interface. The intuitive software actually encourages dialogue with weavers & technicians. Animated machine symbols ensure a user-friendly experience by guiding personnel to the information desired.

State of the Art Technology

The machine utilizes “State  of  the  Art”  Microprocessor Technologywith a PC Board running Windows CE to drive the user interface. Ethernet connectivity allows the Silver 501 to quickly engage both the mill networkand Internet.

With a standard USB memory stick saving,changing or transferring machine settings has neverbeen easier.

Ready for the Future

At Itema, we recognize time is money. This is why we equipped the Silver 501 with our best diagnostic software ever! By simply accessing the touch screen, a functionality test can be selected forany device or application on the machine – even circuit boards. Our Engineersspecifically designed this feature to be utilized without tools or a background in electronicsbut by the people on the floor who operate the machine.
