Lockstitch comparison
JACK A6F-E 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 A6F-E
Digital needle-feed computerized lockstitch with a sealed oil pan and a large 300mm sewing space — feeds smoothly with no short thread tail.
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.
