Lockstitch comparison
JACK A3C vs MAQI LS3820DP: which lockstitch machine should you buy?
A side-by-side look at two lockstitch machines from our catalog: the specifications each one lists, where they differ, and which kind of production each suits. Both are used for garments.
JACK A3C
Computerized single-needle lockstitch machine with auto thread trimmer, from Jack’s A-series — a step up from the A2C with Jack’s newer intelligent control system.
MAQI LS3820DP
MAQI lists the LS3820DP under its Lockstitch series, but its own product page names it a "direct drive chain stitch sewing machine" with a curved-needle construction and a puller/feed panel — closer to a chainstitch/blind-stitch head than a standard lockstitch. Confirm the exact stitch type with a specialist before ordering.
