Lockstitch comparison
MAQI LS3820DP vs MAQI LS9520DP/QB: 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.

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.

MAQI LS9520DP/QB
MAQI's LS9520DP/QB is a direct-drive lockstitch machine with a built-in edge cutter and QB (wrapping) construction, aimed at seams on bags and heavier material that need a trimmed, wrapped edge in the same pass.
