Features ■ The automatic TW series machines consist of a cylinder bed double chainstitch sewing head from 2 to 6 needles. ■ Top and bottom feed, double puller system which compensates the different thickness of the fabric. ■ The ratio between the feeding and rolls are adjusted by a special transmission system assuring perfect synronization and constant stitch length as the speed changes. ■ The cutting and skipping of stitches on both sides of the waistbands can independently be set by the operator. ■ The TW-5910 and TW-5920 models can be used on making naturel looking curved waistbands as a result of perfect feeding of material due to double puller system (upper and lower) using rubber rolls only. ■ This ensures a pucker free seam and no marking on difficult fabrics also compensating for the significant thickness differences on top and bottom of the waistbands. ■ All versions have a push button user interface from which all functions can be controlled. ■ Use of EFKA servo motor and control panel ensures trouble free operation under difficult conditions associated especially in jeans production. ■ 1/8" and 1/4" gauge sizes can be executed simultaneously without conversion on TW-5920 model. ■ The operator can change all rollers and shears within 15 minutes without the need for a mechanic. ■ Longevity, productivity and ease of maintenance are main advantages of our units versus competitor machines. ■ Productivity is up to 2,500 waistbands per 9 hours.
