Karl Mayer Textilmaschinenfabrik GmbH, Germany, has upgraded its RD 6/1-12 and RD 7/2-12 (EL) warp-knit spacer fabric machines used to produce 3-D upholstery fabric and textiles for shoes. Changes include individual needle mounting to facilitate needle changes, and chromium-plated guide elements to protect the yarn sleys from high loads when processing monofilaments in the pile bars.
On the RD 7/2-12 (EL), Karl Mayer has reconfigured the warp beam frame to make it more compact and has modified the machine to simplify pattern changes when using pattern chains.
The company has added to the RD 6/1-12 an optional package for processing multifilament yarns. This package includes special 1-in/1-out guide needles for pile bars GB 3 and GB 4. An accessories kit offers yarn sleys for the pile bars, which allows multifilament yarns to be processed provided the type of yarn and stitch density is considered and meets certain requirements for a machine gauge of E 22.
The company also recently introduced a new Multibar Textronic® Lace series machine for economical lace fabric production. The MT 51/1/32 places more than 32 yarns in front of the fall-plate to enable unique and varied effects in the finished lace in addition to larger widths of lace bands.
The machine currently is supplied in a 134-inch working width and gauge of E 24. The company reports E 18 and E 28 gauges also will be available in the future.
Karl Mayer’s China-based subsidiary Karl Mayer (China) Ltd. will supply the machines, with the first deliveries scheduled the third quarter of this year. Further details about this machine, as well as an entry-level MT 31/1/16 featuring fewer fall-plate yarns and an MT 43/1/24 with fewer guide bars, will be available at ITMA Asia + CITME 2014, to be held in Shanghai June 16-20.
