The SPEEDWAY SW-28BL-20 is a 2-needle, extra-heavy-duty long arm walking foot industrial lockstitch machine built for the heaviest work in the shop — sails, tarpaulins, truck covers, tents, awnings, thick leather, and multi-layer upholstery. Two parallel needles lay down two locked seams in a single pass, and the 20-inch (508 mm) long arm opens up enough throat space to feed bulky, pre-assembled, and rolled material that simply won't fit through a standard machine.
This machine is built around a Japanese hook and Japanese sewing components — the parts that take the punishment on extra-heavy work. Each needle runs its own extra-large vertical-axis hook with reservoir oiling, so the machine holds timing and stitch quality through #8 thread and dense, layered seams. The compound triple-feed system (bottom feed, needle feed, and walking foot top feed all moving in unison) drives thick, slippery, and coated materials through without shifting the layers — the difference between a clean double topstitch and a walked, puckered seam on tough goods.
Driven by a 900W servo motor for high torque at low speed, the SW-28BL-20 punches through 20 mm of material under the foot at up to 1,500 stitches per minute. It ships complete with industrial table and stand, ready to run. The standard needle gauge is 3/8", and it can be changed to another gauge at no additional cost — this adds one to two weeks to the order.
