Lockstitch comparison
JACK 5559F 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 5559F
Lockstitch machine with a digital edge cutter and stepping-motor presser-foot lift, running up to 4000 s.p.m. for shirts, suits, pants and down jackets.

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.
