Definitions

  • the present invention relates to a method and an improved machine for sewing two tubular manufactured products, specially low for forming tights.
  • sewing machines traditionally used in the manufacture of tights include a cable gland foot, which results in the working position located above the two edges which must be united, and an element with horizontal development called "index", which is in turn underlying and united to said foot.
  • index an element with horizontal development
  • the main object of the present invention is to eliminate the aforementioned drawbacks.
  • this comprises, in combination: - means for supporting the two manufactured products to be sewn, with two flat, twin, superimposed shapes, which in the position of sewing the products manufactured are in relative motion with respect to a sewing machine; - Means associated with said support forms, for retaining the edges of the two aforementioned manufactured products to be sewn during sewing, so as to guide, in cooperation with other means, associated with said sewing machine, the two edges in the space delimited by the index and the foot of the same.
  • the advantages deriving from the present invention consist essentially in the fact that it is possible to always obtain a complete and correct seam of very good quality, being always assured the correct positioning of the edges to be sewn, relative to the needle of the sewing machine in its operational phase; that it is possible to obtain the maximum operational speed granted by the sewing machine and this even for products manufactured in very flexible, elastic, light and / or wide mesh fabric and for products manufactured in cotton which, in traditional machines tend to wind on themselves in correspondence with the cut; that a machine according to the invention is of manufacture simple and reliable even after an extended period of use.
  • FIG. 1 shows the plan view of a pair of support forms for stockings in an apparatus according to the invention
  • Fig. 2 shows the plan view of the shapes of FIG. 1 in the open position, where a shaping tights is visible from the top
  • Fig. 3 shows the partial perspective view, a detail of the shapes of FIG. 1
  • Fig. 4 schematically represents the shapes of FIG. 1 in advance with respect to the sewing machine (C);
  • Fig. 5 shows the detail of the index of the sewing machine of FIG. 4.
  • a process for making the union seam of the edges of two tubular manufactured products comprises the phases: of investing each of the two manufactured products (M) on a corresponding form (1) of support so as to place it in a predetermined position on the form (1), to approach successively said forms (1) with the manufactured products thus placed between them, with the sewing edges juxtaposed and protruding from the forms (1), and after moving said forms (1) to place them in correspondence with the needle (5) a sewing machine (C) for sewing the juxtaposed edges of the two manufactured products (M) possibly after trimming said edges.
  • the portion of each protruding edge of the respective shape (1) is oriented in a centripetal manner with respect to the seam line to be made: the edges thus oriented being forced to approach towards and as far as the needle by the same shapes (1) by effect of their relative movement with respect to the sewing machine, between a channel slide converging towards said needle and delimited by the index finger (3) and by the foot (4) in the same way, so that both edges are interposed between the index finger (3) and the foot (4 ) for the duration of the seam.
  • each of said forms (1) is provided, in correspondence with each of its internal edges (11), with an appendage (10) of predetermined length and developed in the longitudinal direction of the form (1): said appendage (10) being oriented centripetally relative to the longitudinal central axis (xx) of the form (1), and therefore prominent from the respective edge (11).
  • the front edge (30) of said index (3) of the sewing machine is advantageously wedge-shaped, with the front falling in the direction of origin of the shapes (1), so as to constitute, in cooperation with the front edge ( 40) of the foot (4) associated therewith, a conveyor element for the insertion - by effect of the relative movement between the shapes (1) and the sewing machine - of the two edges of the manufactured product to be sewn into space between the index finger (3) and the foot (4).
  • said appendage (10) is formed of a plate (P) suitably shaped having one side connectable to the shape (1) and the other free side.
  • the engagement of the plate (P) to the form (1) can be achieved, for example, with screw means.
  • the function of the apparatus described, in the sewing phase of the manufactured products (M), is as follows.
  • the manufactured products (M) to be sewn are placed in the shapes so that the respective free edges are at a predetermined distance (d) from the edge of the corresponding plates (P); said edges being retained adherent by the compression exerted by the closed forms (1), that is to say closely approximated to each other, and oriented centripetally towards the seam line to be produced by the respective appendices (10): such way the spontaneous removal of said line is prevented.
  • each of said manufactured products (M) consists of a bottom which is invested in the respective shape (1) so that its elastic edge (B) is at the height of the corresponding appendix (10 ), at a predetermined distance (d) from the respective free end.
