ABSTRACT:
Disclosed is a stepped embroidery machine. The stepped embroidery machine includes a plurality of head units including heads, embroidery frames installed at lower portions of the heads is such a manner that the embroidery frames are movable in X-axis and Y-axis directions, X-axis drive units for moving the embroidery frames in an X-axis direction, and Y-axis drive units for moving the embroidery frames in a Y-axis direction, a control unit for controlling an operation of the head units, and a control panel used for inputting and displaying information related to embroidery work and embroidery. The head units are individually driven per each head unit and aligned in a stepped pattern while forming a predetermined step difference therebetween. Since the head units are individually driven, it is possible to individually perform embroidery work with respect to various workpieces. The head units are aligned in the stepped pattern while forming a predetermined step difference therebetween, so the head units do not interfere with each other even if the embroidery machine performs the embroidery work with respect to workpieces having a large area. The head units are controlled with one control unit and one control panel, so the worker simultaneously controls the head units of the embroidery machine without changing positions of the worker, facilitating the embroidery work.
