An apparatus for stitching an interior component is disclosed herein. The component having an outer skin layer and the apparatus is a single needle chain stitch machine with a rotary looper and wherein a needle of the apparatus descends through the interior component and a hook of the rotary looper engages a thread loop formed during retraction of the needle after it has descended through the interior component; and wherein the apparatus further includes a mechanism for moving the interior component relative to the needle and looper to establish a stitch length.

A presser foot device includes a pressing member and a guide member provided at the lower end of the pressing member. The guide member has an opening section provided to allow an upper thread to pass therethrough in a rotating direction of a rotary hook, and a restricting section provided to restrict movement of the upper thread in a direction opposite the rotating direction of the rotary hook. Upon determination that a direction in which a next stitch is to be formed belongs to a predetermined hitch-stitch forming area, detouring movement of a frame, holding the sewing workpiece, is carried out. This detouring movement includes moving the frame in such a direction in which the upper thread moves out of the opening section and then further moving the frame to a target position corresponding to the next stitch such that the upper thread abuts against the restricting section.
