Abstract
A head unit fixed sewing machine is provided, which includes a table, support posts, an upper beam, a head unit and a bed unit. An object is placed on the table. The support posts are provided on opposite sides of the table. The upper beam connects the support posts to each other and is coupled to upper ends of the support posts. The head unit is fastened to the upper beam and has a head-unit-rotating means for rotating a sewing head within a predetermined range. The bed unit is provided below the head unit and has a bed-unit-rotating means for rotating a sewing bed within a predetermined range. Because the head unit and the bed unit can be rotated while sewing, the orientation of a sewn thread can be maintained constant. Hence, a perfect stitch can be realized over the entirety of the object.
