Claims
- 1. A process of making garments formed of helically joined pieces, which comprises feeding from a supply roll a continuous strip of garment material, propelling said strip helically around a cylindrical form with edges of adjacent convolutions of said material contiguous with one another while joining said contiguous edges of adjacent convolutions of said material to form a tubular structure, and cutting said material in predetermined manner into garment lengths and to provide any openings required in said garments.
- 2. A process according to claim 1, in which said cutting is performed prior to said joining.
- 3. A process according to claim 1, in which said cutting is performed subsequent to said joining.
- 4. A process according to claim 1, in which said strip of garment material comprises a flattened seamless tube.
- 5. A process according to claim 1, in which said strip of material comprises a flattened tube formed of a strip of material wound in helical form with contiguous edges of adjacent convolutions of said material joined together.
- 6. A process according to claim 1, in which said strip comprises a plurality of superposed layers of material.
- 7. A process according to claim 6, in which said layers of material comprise an upper layer, a lower layer and an intermediate layer of material different from the material of said upper layer.
- 8. A process according to claim 1, in which said edges of adjacent convolutions of said material are joined by adhesive means.
- 9. A process of making garments formed of helically joined pieces which comprises feeding from supply rolls a plurality of continuous strips of garment material in side-by-side relation with adjacent edges contiguous, joining contiguous edges of said strips to form a wider composite strip, propelling said composite strip helically around a cylindrical form with edges of adjacent convolutions of said composite strip contiguous with one another while joining said contiguous edges to form a tubular structure, and cutting said material in predetermined manner into garment lengths and to provide any openings required in said garments.
- 10. A process according to claim 9, which includes forming said plurality of strips of material by longitudinally splitting wider material.
- 11. A process according to claim 9, in which said cutting is performed after the joining of said strips to form said composite strip and before propelling said composite strip helically about said form.
- 12. A process according to claim 9, in which said cutting is performed subsequent to formation of said tubular structure.
- 13. Apparatus for making garments formed of helically joined pieces, which comprises a cylindrical form, means for feeding to said form a strip of garment material from a supply roll containing a continuous length of said material, means for propelling said strip of material helically around said form with edges adjacent convolutions of said material contiguous with one another, means for joining said contiguous edges of adjacent convolutions of said material to form a tubular structure, and means for cutting said material in predetermined manner into garment lengths and to provide any openings required in said garments.
- 14. Apparatus according to claim 13, in which said cutting means is located ahead of said joining means.
- 15. Apparatus according to claim 13, further comprising means for taking-up said tubular construction as it is discharged from said form.
- 16. Apparatus according to claim 15, in which said take-up means comprises a reel, means for driving said reel to take-up said tubular structure and means mounting said reel for rotation about an axis perpendicular to the axis of said reel.
- 17. Apparatus for making garments formed of helically joined pieces, which comprises means for feeding from supply rolls a plurality of continuous strips of garment material in side-by-side relation with adjacent edges contiguous, first means for joining said contiguous edges of said strips to form a wider composite strip, a cylindrical form, means for propelling said composite strip helically around said cylindrical form with edges of adjacent convolutions contiguous with one another, second means for joining said contiguous edges of said composite strip to form a tubular structure, and means for cutting said material in predetermined manner into garment lengths and to provide any openings required in said garments.
- 18. Apparatus according to claim 17, in which said cutting means is located between said first and second joining means.
- 19. Apparatus according to claim 17, in which said first joining means comprises sewing means for joining said contiguous edges of said plurality of strips by stitching.
- 20. Apparatus according to claim 17, in which said feeding means comprises means for feeding a tape beneath adjacent edges of said strips and said first joining means comprises sewing means for stitching said adjacent edges of said strips to said tape.
- 21. Apparatus according to claim 20, in which said sewing means comprises a presser foot engaging said material and guide wheels carried by said presser foot and engaging adjacent strips of material to guide them as they are being stitched to said tape.
- 22. In a sewing machine the combination of a sewing head having two needles spaced laterally from one another, a presser foot mounted below said sewing head in position to engage material being stitched and means for guiding said material, said guiding means comprising mounting means, means for affixing said mounting means to said presser foot, an inverted U-shaped bracket adjustably carried by said mounting means with downwardly extending legs at opposite sides of said presser foot and guide wheels rotatably mounted on said legs of said bracket in position to engage the material being stitched.
- 23. A combination according to claim 22, in which said wheels are rotatably mounted on inclined axles with said wheels inclined downwardly toward one another.
- 24. Apparatus according to claim 17, further comprising means upstream of said first joining means for splitting a wider piece of material to form said plurality of strips.
- 25. Apparatus according to claim 24, in which said splitting means comprises means providing an elongated cutting zone, means for continuously feeding material from a supply roll to and through said cutting zone, a support bar extending lengthwise of said cutting zone, a plurality of cutting instrumentalities mounted on said bar for adjustment to different positions along said bar and engaging said material to split it as it passes through said cutting zone to form a plurality of strips of material and means for taking-up said strips of material as they are formed.
