Abstract

An embroidery machine (1), comprising a crochet hook (2) and a needle bar (16), an engagement part (21) capable of fixing the needle bar (16) in two directions different by 180° from each other, a looper (4) guiding a thread to the hook part (2a) of the crochet hook (2), a feed mechanism (5) moving a sewn article (A) in a prescribed feed direction (P), an orientation adjusting mechanism (6) capable of setting the feeding direction (P) of the feed mechanism, the orientation of the crochet hook (2), and the orientation of the looper (4) in synchronism with each other by reciprocatingly moving in the axial direction to rotate a spindle (15) transmitting a reciprocating motion (Q) to the looper (4) without allowing the spindle to be interlocked with the reciprocating motion (Q), and a looper orientation changeover part (7) capable of rotating the orientation of the looper (4) by 180° independently of the orientation adjusting mechanism (6).
