Two or more bridges (21, 22) are provided having separate motion control. Each bridge (21, 22) has a row of selectively operable stitching element pairs (90), which may be fixed to or transversely moveable on the bridges (21, 22). The bridges (21, 22) each move transversely and vertically with the stitching elements on each being operable at different speeds. Each bridges is driven by linear servo motors (45, 46) and all the needle drives (25) and looper drives (26) on a bridge are respectively driven by a common servo motor (67, 69).
