Abstract
An automatic sewing apparatus is disclosed for sewing together a pair of first edges of two overlapped bodies by a cross seam, each of the bodies being formed by sewing together a pair of second edges of two pieces of overlapped cloth, wherein the two bodies are layered with the margins to the seam of the second edges facing away from each other, and the apparatus comprising a sewing device for sewing the overlapped bodies together, a table for supporting the bodies to be sewn, and a sewn edge fold-down device for folding down the margin of one of the bodies in the direction to feed the cloth, and the margin of the other body in the opposite direction before sewing the first edges.
Claims11
An automatic sewing apparatus useful for sewing together a pair of first edges of two overlapped bodies, each of said overlapped bodies having been formed by sewing together a pair of second edges of two pieces of overlapped cloth, the sewn pair of second edges of each of the overlapped bodies intersecting the first edge of the respective overlapped body, each of the pairs of second edges forming a corner at the intersection with the first edge, the two overlapped bodies being layered one above the other with the sewn pairs of second edges extending away from each other and the first edge and the sewn pair of second edges of one of the overlapped bodies being directly above the first edge and the sewn pair of second edges of the other overlapped body, the apparatus comprising:
- sewing means for sewing the first edges;
- a table for supporting the bodies to be sewn by the sewing means, the bodies to be sewn being fed along the table to the sewing means;
- and
- sewn edge fold-down means for folding down said sewn pair of second edges at the corner of one of the bodies on top of the bodies in the direction of feeding the cloth to the sewing means, and for folding said sewn pair of second edges at the corner of the other body beneath the bodies in the opposite direction, before the first edges are sewn by said sewing means.
An automatic sewing apparatus for forming a cross seam over two pieces of overlapped bodies, each of the bodies being formed from two pieces of cloth by forming a plain seam over edges of the two pieces, the two pieces of overlapped bodies being layered with margins of the plain seam facing away from each other and the plain seams being arranged so that one lies directly above the other, comprising:
- a sewing machine for forming the cross seam;
- a table for supporting the bodies to be sewn by the sewing machine, the bodies to be sewn being fed to the sewing machine along the table;
- and
- a hand for folding two pieces of layered bodies before they are sewn by the sewing machine, wherein the hand includes a fork horizontally supported for holding individually each margin formed by the plain seam of the two pieces of the layered bodies, and rotation means for rotating the fork around a horizontal axis.
An automatic sewing apparatus useful for sewing together a pair of first edges of two overlapped bodies, each of said overlapped bodies having been formed by sewing together a pair of second edges of two pieces of overlapped cloth, the sewn pair of second pair of each of the overlapped bodies intersecting the first edge of the respective overlapped body, each of the pairs of second edges forming a corner at the intersection with the first edge, the two overlapped bodies being layered one above the other with the sewn pairs of second edges extending away from each other and the first edge and the sewn pair of second edges of one of the overlapped bodies being directly above the first edge and the sewn pair of second edges of the other overlapped body, the apparatus comprising:
- sewing means for sewing the first edges;
- a table for supporting the bodies to be sewn by the sewing means, the bodies to be sewn being fed along the table to the sewing means;
- and
- sewn edge fold-down means for folding down said sewn pair of second edges at the corner of one of the bodies on top of the bodies in the direction of feeding the cloth to the sewing means, and for folding said sewn pair of second edges at the corner of the other body beneath the bodies in the opposite direction, before the corners are sewn by said sewing means.
An automatic sewing apparatus for forming a cross seam over two pieces of overlapped bodies, each of the bodies being formed from two pieces of cloth by forming a plain seam over edges of the two pieces, the two pieces of overlapped bodies being layered with margins of the plain seam facing away from each other and the plain seams being arranged so that one lies directly above the other, comprising:
- a sewing machine for forming the cross seam;
- a table for supporting the bodies to be sewn by the sewing machine, the bodies to be sewn being fed to the sewing machine along the table;
- and
- a hand for folding two pieces of layered bodies before the cross seam is formed at the plain seams, wherein the hand includes a fork horizontally supported for holding individually each margin formed by the plain seam of the two pieces of the layered bodies, and rotation means for rotating the fork around a horizontal axis.
