Abstract
An apparatus for sewing has a sewing head with a stitching station at which stitching occurs on material fed therethrough. A turntable holds material to be stitched in its position adjacent to the sewing head. The turntable has an outer perimeter with a portion of the outer perimeter extending through the stitching station. Fabric material is held along the perimeter and stitched as the turntable rotates so that during stitching the turntable rotates and feeds material into the stitching station of the sewing head. In a preferred embodiment, the turntable includes upper and lower platens and magnets positioned on the upper platen for locking upper and lower platens together and holding fabric material therebetween.
Claims33
An apparatus for sewing comprising
- a sewing head having a stitching station at which stitching occurs on material fed therethrough, and
- a turntable for holding material to be stitched and positioned adjacent said sewing head, said turntable having upper and lower platens and having an outer perimeter with a portion of said outer perimeter extending through said stitching station, and including magnetic means along the perimeter of said turntable for holding material to be stitched, and means for rotating said turntable so that during stitching said turntable rotates and feeds material into said stitching station of said sewing head.
An apparatus for sewing comprising
- a sewing head having a stitching station at which stitching occurs on material fed therethrough, and
- a turntable for holding material to be stitched, said turntable including
- a lower platen having an outer perimeter,
- means rotatably supporting said lower platen so that a portion of said outer perimeter of said platen extends through said stitching station,
- an upper platen having an outer perimeter,
- means supporting said upper platen in spaced relation above said lower platen, said upper platen being substantially aligned with said lower platen, and
- magnetic means positioned on at least one of said platens for attracting said platens for locking material to be stitched between the two platens so that during stitching, said platens rotate and feed material held therebetween into said stitching station of said sewing head.
An apparatus for sewing comprising
- a sewing head having a stitching station at which stitching occurs on material fed therethrough,
- a horizontally configured support plate,
- a vertically aligned lower support shaft rotatably mounted on said support plate,
- a circularly configured lower platen secured on said support shaft and horizontally aligned thereon, said platen having an outer perimeter, said shaft and platen being positioned so that a portion of said outer perimeter of said platen extends through the stitching station,
- a support arm secured to said support plate and including an upper bridge arm extending above said lower platen,
- an upper support shaft rotatably supported by said upper bridge arm and vertically aligned with said lower support shaft,
- an upper platen secured to said upper support shaft, said upper platen having an outer perimeter aligned with said lower platen,
- means for moving said upper support shaft to move said upper platen into overlapping engagement with said lower platen, and
- magnetic means positioned on said upper platen for attracting said lower platen for locking material to be stitched between the two platens so that during stitching, said platens rotate and feed material held therebetween into said stitching station of said sewing machine.
An apparatus for holding material to be stitched at the stitching station of a sewing head comprising
- a lower platen having an outer perimeter,
- means rotatably supporting said lower platen,
- an upper platen having an outer perimeter,
- means supporting said upper platen in spaced relation above said lower platen, said perimeter of said upper platen being aligned with said lower platen, and
- magnetic means positioned on one of said platens for attracting said platens for locking material to be stitched between the two platens so that during stitching, said platens rotate and feed material held therebetween into a stitching station of a sewing head.
An apparatus for holding material to be stitched at the stitching station of a stitching head comprising,
- a horizontally configured support plate,
- a vertically aligned lower support shaft rotatably mounted on said support plate,
- a circularly configured lower platen secured on said support shaft and horizontally aligned, said platen having an outer perimeter,
- a support arm secured to said support plate and including an upper bridge arm extending above said lower platen,
- an upper support shaft rotatably supported by said upper bridge arm and vertically aligned with said lower support shaft,
- an upper platen secured to said upper support shaft, said upper platen having an outer perimeter aligned with said lower platen,
- means for moving said upper support shaft to move said upper platen into overlapping engagement with said lower platen, and
- magnetic means positioned on said upper platen for attracting said lower platen for locking material to be stitched between the two platens so that during stitching, said platens rotate and feed material held therebetween into a stitching station of a sewing machine.
