BT400

BT400 Double-motor Platform Two-wheel Electronic Puller for Sewing Machine

The BITOP BT400 is a double-motor, two-wheel electronic puller that mounts above the sewing machine table and pulls fabric through at a steady rate, keeping the feed even. It solves unsmooth sewing, wrinkling, slipping and staggered layers, and raises efficiency by 50-200% compared with sewing without a puller. New fabrics are quick for operators to learn and fast to sew. The control box is integrated into the puller and uses a double closed-loop stepper motor system for more accurate synchronisation. It supports sewing machine speeds over 6000 rpm, and motor service life is 200-500% longer than a traditional DC motor. There is no gearbox and no oil leakage, and it runs ultra-quiet. Presser foot lifting, reverse sewing and thread trimming signals adapt to all flat sewing machines; a computer flat sewing machine reads the signal directly without installing an encoder. It fits single needle, double needle, walking foot, chain stitch and heavy duty heads, and is used for home textiles, clothing, outdoor equipment, dust prevention and home furnishings. 80-240 V, 2-120 W. Supplied new from Zhejiang, China with a one year warranty on core components; machinery test report and video outgoing-inspection are both provided.
