The JACK® W4-UT-01GBX364 is an industrial flatbed coverstitch machine for apparel workshops producing knit garments and stretch-fabric seams. Its three-needle, five-thread arrangement supports consistent parallel stitching for garment assembly and finishing operations.
The flat sewing surface provides room to guide garment panels during production, while the differential feed can be adjusted to suit the way a fabric stretches or advances. A Direct Drive motor and automatic thread trimming help operators move efficiently between sewing operations.

JMJ Sewing Machines Recommends
JMJ Sewing Machines recommends testing differential feed and thread tension on a sample of the actual production fabric before running a batch. For stretch garments, check that the finished seam lies flat and retains the flexibility required by the design. JMJ assembles, adjusts, and sewing-tests its industrial setups before delivery.
