New Proposals in Textiles Using Two Loop Presser Beds

SHIMA SEIKI’s latest SRY123LP and SRY183LP are completely new computerized knitting machines that inherit SHIMA SEIKI’s highly advanced mechatronics know-how based on the company’s unique experience with four-bed knitting, beginning with the legendary SES122RT, and continuing with SWG-FIRST and MACH2X. Two loop presser beds improve on the stitch presser by controlling pressdown of individual loops. This presents unprecedented capability in knitwear, especially with flechage and inlay patterns. New fabrics with woven effects offer great opportunities in expanding into other markets. Specialty yarns such as metallic and monofilament yarns can be knit as well, opening new doors to areas other than fashion. A high level of productivity typical of SHIMA SEIKI is carried over, with a maximum knitting speed of 1.4 meters per second combined with quick carriage returns realized with the proven R2CARRIAGE system. SHIMA SEIKI’s original DSCS Digital Stitch Control System, yarn gripper and cutter, and takedown comb all contribute to high quality and productivity as well.
