Japanese textile solutions provider Shima Seiki will exhibit at the upcoming JEC World 2020 exposition where it will unveil a new prototype weft-knitting machine that is capable of multiaxial insertion. Fabrics produced on the prototype machine use inlay technique for the production of hybrid textiles that combine the stretch characteristics of knitted fabrics with the stability of woven textiles, suited to various technical applications, the company says. Warp insertion further expands the capability of the machine to produce 3Dshaped carbon fibre and composite preforms directly on the machine. This is made possible because flat knitting as a textile production method is capable of producing end products that are shaped to form and with added thickness. There are number of further advantages to this machine. For example, savings in post-processing time, cost, material and labour as compared to current methods of preform production are immense, realizing efficient and sustainable production. The company’s own yarn unwinding technology is also used for optimum yarn feed and tension for use with technical yarns that are otherwise difficult to knit.
Also on display is the PCAM131 multiply computerized cutting machine (NC cutting machine). This fast, efficient and reliable PCAM series computerized cutting machines are known for their innovative functions and Made in Japan quality, and boast the largest market share in Japan. PCAM131’s multiply cutting capability allows up to 1 inch (33mm) of fabric or material to be cut.
At JEC World PCAM131 is shown in its most compact form, featuring a cutting area of 1,300 mm x 1,700 mm, with option for expansion. A knife sharpening system produces a sharp, strong blade every time. Strong, robust components permit quicker response times for knife movement and more accurate cutting of composites and other industrial materials.
At the show, demonstrations will also be performed on Shima SeikI’s new SDSONE APEX4 design system, the fourth generation of its series and the most powerful, most efficient APEX to date. Processing speeds for programming and simulation are improved by up to 600 per cent compared to the previous generation SDSONE APEX3, for quicker response especially in virtual sampling. Virtual sampling based on ultrarealistic simulation improves on the design evaluation process by minimizing the need for actual sample-making in prototyping. This realizes significant savings in time, cost and material, further contributing to sustainable manufacturing. Once a design is approved, production data can be created for both knitting machines and cutting machines.
JEC World takes place in Paris from 3-5 March 2020 at the Parc des Expositions de Paris Nord Villepinte, Halls 5 & 6. Shima Seiki can be found in Hall 6, Booth P28
