Abstract
A shuttle embroidery machine having an attachment, corresponding to each needle, for the selective application of dish-shaped sequins onto a cloth wherein the continuous strip of dish-shaped sequins is indexed by a rotary feed wheel through a feed member having a channel for guiding the dish-shaped sequins for severance. Each dish-shaped sequin sequentially exits the channel by a cutting blade actuated at appropriate times in coordination with the needle that sews each dish-shaped sequin to the cloth.
Claims8
A shuttle embroidery machine with a plurality of needles and corresponding sequin guide attachments for automatically and selectively applying dish-shaped sequin-like decorations to fabric, the machine including a dish-shaped sequin guide attachment that comprises:
- a frame with a vertical chute having an exit;
- a rotary coin feed wheel for indexing a strip of continuously connected dish-shaped sequins through the vertical chute to enable each dish-shaped sequin to be sequentially severed from the strip as the dish-shaped sequin exits from the chute;
- a sequin guiding device positioned in the chute and extending partially along the length of the chute for guiding the strip of dish-shaped sequins from the rotating coin feed wheel into and down the chute;
- a plate secured on one side to the frame and positioned in the vertical chute over the guiding device such that the sequins move down the chute under the plate;
- a feed shaft inserted through the axis of the rotating coin feed wheel for incrementally and rotatably positioning the wheel such that each dish-shaped sequin exits the vertical chute sequentially;
- an elongated bar mounted on the machine for slidably receiving the feed wheel such that the feed wheel and the frame with the vertical chute are slidably adjustable along the bar with respect to the machine;
- an elongated blade pivotally attached to the vertical chute and forming a cutting surface;
- a projection slidably attached to the needle bar for each needle;
- and
- a piston coupled to the projection for slidably aligning the projection with the pivotable elongated blade such that the projection forces the blade into the dish-shaped sequin to sever the sequin from the strip of dish-shaped sequins.
A process for automatically attaching dish-shaped sequins to a fabric with a needle on the needle bar of a shuttle embroidery machine comprising the steps of:
- incrementally feeding a strip of continuously connected dish-shaped sequins to a feed member, and thereafter exiting each dish-shaped sequin sequentially from the feed member;
- guiding the dish-shaped sequins on a rotating feed wheel with a flexible guiding device extending partially lengthwise of a chute forming a portion of the feed member such that the sequins move into and travel through the chute and exit the chute sequentially;
- coordinating movement of the needle towards the fabric to sew a sequin on the fabric with movement of a pivotable elongated blade as a cutting means;
- and
- pushing the pivotable elongated blade from a normal stationary position into cutting engagement with the dish-shaped sequin in a plane perpendicular to the plane of the sequin to sever the sequin by means of a needle bar projection selectively aligned with and engaging the pivotable elongated blade.
