Detail

How it runs on the floor

The JACK K6-A-UT is a computerized 3-needle cylinder bed coverstitch machine with a built-in left-hand knife, automatic thread trimmer, and integrated electric suction system — no air compressor required. The knife trims the fabric edge simultaneously during sewing, the suction system vacuums trimmed waste directly at the source, and the automatic thread trimmer completes the cycle hands-free. The cylinder bed provides direct access to tubular and curved garment sections for clean, efficient hemming at up to 5,500 SPM on activewear, casualwear, and children's garments. Comes as a complete setup with table and stand included.
