Abstract
A work-sheet feed apparatus in which an X carriage is coupled integrally with a coupling member. A rear end portion of a holder support is coupled to the coupling merber via a coupling mechanism that supports the holder support pivotally about an axis parallel to the X direction, while a work-sheet holding frame that holds a work sheet is attached only at one side thereof to a frame holder secured to the holder support. With this arrangement, when a base frame vibrates in the vertical direction during embroidering, due to vertical movement of the needle bars or the presser feet during embroidering, the vertical vibration is dampened or isolated by the coupling mechanism, and is not transmitted to the holder support Because the work sheet held by the work-sheet holding frame does not vibrate in the vertical direction, threads are sufficiently tightened during the formation of the stitches on the work sheet, with no occurrence of stitch skipping or thread breakage, thus making it possible to form high-quality stitches.
