Definitions

  • Thisinvention relates to edge finishing seams and is particularly advantageous when used to sew together the edges of two plies of fabric which are susceptible of ravelling or of which the individual fibers have poor cohesive qualities and tend to separate readily.
  • stitched seams at least two separate lines of stitching were required in order to bind each of the two ply edges with threads and stitch the plies together.
  • This invention provides for the edge stitching of fabrics such as knit goods which can ravel or of fabrics of which the fibers can pull out easily as in the case of many fabrics woven of synthetic material.
  • a single row of stitches parallel to the edges of the plies of fabric secures the plies together and a separate edge covering thread is arranged back and forth over the edge of each of the plies of fabric with loops of the edge covering threads embracing the stitches in the row of securing stitches alternately between the plies and at one side of the plies.
  • FIG. 1 represents a diagrammatic perspective view of the stitched seam of this invention in which the plies of work fabric are illustrated in abnormally spaced relation and in phantom lines, and in which each of the threads forming the seam are shown with a different shading,
  • FIG. 2 represents a perspective view of a fragment of work fabric formed with a seam of this invention and in which the various threads are shaded corresponding to the shading used in FIG. 1, and
  • FIG. 3 is a cross sectional view taken substantially along the single row of stitches.
  • the upper and lower plies of fabric are designated by the reference characters 11 and 12 respectively.
  • the securing stitches 13 illustrated in the drawings are two-thread chainstitches, Federal Stitch Type 401, but it will be understood that any other type of stitch providing a single row of concatenated thread loops through the fabric may be used.
  • an edge covering thread 17 is formed into successive loops 18 over the upper ply 11 and loops 18 under the upper ply, i.e., the loops 18 extend between the plies 11 and 12 as clearly shown in FIG. 3.
  • Each of the loops 18, 18 embraces one of the upper thread loops 15 in the securing seam 13 and between the loops 18, 18' the thread extends over the edge 11' of the upper fabric ply 11.
  • An edge covering thread 19 is similarly provided for binding the edge 12 of the lower fabric ply 12.
  • the thread 19 is formed into successive loops 20 under the lower ply r12 and with loops 20' over the lower ply, i.e., between the plies.
  • Each of the loops 20, 20' embraces one of the upper thread loops 15 in the securing seam 13 and between the loops 20, 20' the thread extends over the edge 12" of the lower fabric ply.
  • both edge covering threads 17 and 19 embrace each loop 15 of the row of securing stitches to provide the greatest density of edge covering stitches.
  • the seam in accordance with this invention may be formed with either or both of the edge covering threads engaging less than all of the securing stitch loops with a resultant decrease in density of the threads extending over the edge of the fabric plies. It is also preferable as shown in the drawing, for only one of the edge covering threads 17 and -19 to be formed with a loop 18 or 20' extending between the plies in embracing relation with any one loop 15 of the securing seam 13'.
