ABSTRACT:
In a machine for embroidering a workpiece of the type having a needle magazine, a plurality of needles movably mounted to the needle magazine to define a needle groove, each needle of the needle group equipped with a different thread, and a mechanism for selectively imparting axial reciprocatory movement to the needles of the needle group to perform a thread change, an improved arrangement is disclosed in which the reciprocating mechanism includes a single elongated needle bar associated with the group. The needle magazine is movable relative to the needle bar to selectively align each needle with the needle bar. A disengaging coupling permits a selected needle of the needle group to be coupled to the needle bar. A locking mechanism is provided for detachably locking each of the needles to the needle magazine.
