CONSEW® CM794-2 2-Needle 4-Thread Industrial Overlock Sewing Machine – Complete with Table & Stand
FULLY ASSEMBLED | TABLE, MOTOR & STAND INCLUDED
Professionally assembled, adjusted and sewing-tested by JMJ Sewing Machines before delivery.
2 Needles • 4 Threads • Mock Safety Stitch • Differential Feed • Up to 6,500 SPM
The CONSEW® CM794-2 is an industrial overlock machine configured for two-needle, four-thread mock safety stitching. It is suited to production lines that join stretchable fabric panels while finishing the edge in a single operation.
Its differential feeding mechanism helps operators control material movement on knit fabrics. Automatic lubrication, a visible oil-flow indicator, and a replaceable oil filter support regular production use.
At JMJ Sewing Machines, we recommend this configuration for apparel workshops producing swimwear, knit shirts, children's clothing and other stretch garments that require consistent overlock seams.
