Built for tight, small-diameter seams that a standard overlock arm cannot reach.

The Jack JK-797 is a small cylinder-bed overlock machine. Its slim 148mm bed head fits inside T-shirt necklines, cuffs, and other small tubular openings. UAE uniform and sportswear workshops use it for collar bands, sleeve cuffs, and sock tops. It also suits abaya and kandoora workshops that finish narrow sleeve and hem openings.

  • Top differential feed option (TDI) keeps fabric straight during feeding
