Karl Mayer's knitting machines shown at ITMA 1999 featured improved performance, flexibility, productivity, and ease of use. The tricot knitting machines incorporated an improved version of the electronic beam drive. The HKS4 tricot machine uses a pile device to form pile loops with a uniform height for upholstery fabrics. The RSE4-1 raschel machine operates at speeds of up to 2,500 courses per minute. The RJPC4F-NE jacquard raschel machine operates at speeds of up to 700 courses per minute and uses the latest piezo jacquard technology to manufacture net curtains, tablecloths, and women's outerwear fabrics. The RS(2)MSUS loom for technical textiles operates at speeds of up to 1,000 courses per minute when weaving glass yarns and up to 1,400 courses per minute when weaving polyester filament yarns. 5 refs.
