Claims12
An apparatus for stitching an interior component, the interior component comprising an outer skin layer, and wherein the apparatus is a single needle chain stitch machine with a rotary looper during operation of the apparatus 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 rotary looper is rotatably driven by a horizontal shaft that is operably coupled to and extends from a vertical shaft such that the rotary looper is offset from vertical shaft and the apparatus further comprises a mechanism for moving the interior component relative to the needle and the looper to establish a stitch length, wherein a robot is coupled to a sewing head having the needle, the robot moving the sewing head with respect to the interior component.
An apparatus for stitching an interior component, the interior component having an outer skin layer, and the apparatus is a single needle chain stitch machine with a rotary looper 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, wherein the rotary looper has an arm member configured with an offset such that the hook is offset axially from other portions of the arm member, the arm member being directly driven by a lower shaft coupled to a motor, the motor also driving an upper shaft that drives the needle;
- and wherein the apparatus further comprises a mechanism for moving the interior component relative to the needle and the looper to establish a stitch length.
