Lockstitch comparison
MAQI LS3820DP vs MAQI Q7T: 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.

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 Q7T
MAQI's Q7T is an electronically controlled lockstitch machine built around quiet operation — silent electronic backtack, double-knife thread trimming that leaves a short thread end, and a closed automatic oil-pan lubrication system that keeps the machine and fabric free of oil stains.
