Abstract

Claims (31)

1. A texture hoop for use in a sewing machine, the texture hoop comprising:

a fixture having a central opening and a plurality of recesses spaced adjacent the central opening, the fixture configured to affix a base fabric stretched across the central opening to the fixture edges; and

means for securing at least one embellishment to the fixture.

2. The texture hoop of claim 1 , wherein the plurality of recesses are evenly spaced at intervals along at least one edge of the fixture.

3. The texture hoop of claim 1 , wherein the means for securing the embellishment to the fixture comprises securing the embellishment within at least one of the recesses spaced around the central opening.

4. A texture hoop for use in a processor controlled sewing machine, the sewing machine having a presser foot and a processor controlled embroidery unit, the texture hoop configured for mounting upon the embroidery unit, the embroidery unit configured for moving the texture hoop along perpendicular first and second coordinate axes relative to the sewing needle, the texture hoop comprising:

a fixture having a central opening configured to affix a base fabric stretched across the central opening to the fixture edges;

the position of the fixture relative to the sewing needle being processor controlled along the perpendicular coordinate axes of the embroidery unit, each coordinate axis being divided into coordinate units relative to an origin, the needle position relative to the fixture then being expressed in the processor as a first coordinate value along the first axis, and a second coordinate value along the second axis;

means for securing an embellishment laying upon the base fabric to the fixture;

at least one positional reference on the fixture for relating the location of a received embellishment positioned upon the base fabric to the units of each coordinate axis;

wherein the at least one positional reference is used to generate a stitch pattern start location and a stitch pattern end location coordinate values to secure the received embellishment to the base fabric.

5. The texture hoop of claim 4 , wherein the at least one positional reference comprises the coordinate units of the first and second coordinate axes marked upon the texture hoop fixture.

6. The texture hoop of claim 4 , wherein the at least one positional reference comprises the origin of the first and second coordinate axes marked upon the texture hoop fixture.

7. The texture hoop of claim 4 , wherein the at least one positional reference comprises a semi-transparent template marked with the coordinate units of the first and second axes and is configured to be received in the central opening of the fixture.

8. The texture hoop of claim 4 , wherein the at least one positional reference comprises a semi-transparent template marked with the coordinate origin of the first and second coordinate axes and is configured to be received in the central opening of the fixture and having the coordinate origin of the first and second coordinate axes marked thereon.

9. The texture hoop of claim 4 , wherein the at least one positional reference on the fixture comprises a plurality of evenly spaced recesses positioned along at least one edge of the fixture and adjacent the central opening.

10. The texture hoop of claim 9 , wherein the means for securing the embellishment to the fixture comprises securing the embellishment within at least one of the recesses spaced around the central opening.

11. The texture hoop of claim 4 , wherein the means for securing the embellishment to the fixture comprises at least one of a spring clip, a magnet, a wedge, a pin, or a hook.

12. The texture hoop of claim 4 , wherein the means for securing the embellishment to the fixture comprises a protruding lip on the fixture and at least one spring clip configured to engage the protruding lip.

13. The texture hoop of claim 12 , wherein the at least one positional reference on the fixture comprises a plurality of recesses spaced adjacent the central opening and configured to communicate with at least one spring clip to receive and secure an embellishment.

14. The texture hoop of claim 4 , the fixture further comprising a first inner hoop and a second outer hoop, the inner and outer hoops having a central opening configured to clamp a base fabric stretched across the central opening between the first inner hoop and the second outer hoop.

15. A method of sewing an embellishment to a base fabric using a processor controlled sewing machine having sewing needle and a texture hoop configured for mounting upon an embroidery unit of the sewing machine, the embroidery unit configured to move the texture hoop along perpendicular first and second coordinate axes relative to the sewing needle, the texture hoop having a fixture comprising a first inner hoop and a second outer hoop, the inner and outer hoops having a central opening, the method comprising:

stretching a base fabric across the central opening of the fixture and clamping the base fabric between the first inner hoop and the second outer hoop;

positioning at least one embellishment upon the base fabric;

securing the at least one embellishment to the fixture;

determining the position of the texture hoop fixture relative to the sewing needle;

expressing the position of the texture hoop fixture relative to the sewing needle in the sewing machine processor as a first coordinate value along the first axes, and a second coordinate value along the second axes;

determining embellishment location coordinate values by using positional references of the texture hoop fixture that relate the embellishment location to the units of each coordinate axis;

programming the processor of the sewing machine with coordinate values corresponding to the embellishment location;

using the programmed embellishment coordinate values and the texture hoop position relative to the sewing needle to generating a stitch program to sew the embellishment onto the base fabric; and

executing the stitch program to sew the embellishment onto the base fabric.
