Pegasus and JACK meet head-on in the overlock and coverstitch aisle. Pegasus, founded in Japan in 1914, is a century-old specialist focused almost entirely on overlock, coverstitch, and flatseam machines, with deep engineering in those stitch types. JACK, founded in 1995, is the world's largest industrial sewing machine maker by units and turnover, and it offers capable overlock and coverstitch as part of a full nine-family catalog. The trade-off is specialist depth versus single-brand breadth. JACK's E4S and C7 overlocks cover 3- to 6-thread edge finishing with direct-drive motors and, on the C7 AI line, automatic material adjustment; the K5 and W4 coverstitch machines handle cylinder and flatbed hemming. Pegasus is the deeper specialist if overlock and coverstitch are your entire business; JACK is the stronger value if you want competitive edge-finishing and the convenience of buying your lockstitch, heavy-duty, and finishing machines from the same brand.

Where Pegasus leads
If your shop is built around knit production and edge finishing — and overlock and coverstitch are most of what you run — Pegasus's century of specialist focus shows in the depth and refinement of those machines. A dedicated specialist is a defensible choice for a dedicated operation.
Where JACK leads
Most floors run edge finishing alongside seaming, hemming, and heavy work. JACK lets you buy a competitive overlock and coverstitch from the same brand as your lockstitch and walking-foot machines, with the C7 AI overlock automatically adjusting to the material. One brand across the floor simplifies parts and service.
The overlock and coverstitch lineup
JACK's E4S covers 3-, 4-, 5-, and 6-thread overlock; the C7 adds AI material sensing. For coverstitch, the K5 is a 3-needle cylinder-bed machine for tubular hems and the W4 is a flatbed for general hemming and topstitching. Differential feed keeps knits flat. All are linked below.
