What the Jack E4S catalogue covers

Two pages in English: the cover, then the features and a specification table that lists the E4S builds from 2 to 6 threads, for plain seams, back latching, binding, narrow edges, tape, towels, denim and extra heavy fabric.

The A, M and H settings move the machine between fabric weights by one lever, so a line can go from T-shirts to denim between orders. Al Borj supplies, installs and services the E4S from Sharjah and Accra.

Machine type: Light and heavy adjustable overlock machine.
