Definitions

  • the present invention relates to a device for flattening and ironing the seam zone between two layers of fabric which have been sewn together on a sewing machine.
  • a device for flattening and ironing a seam zone between first and second layers of fabric each said fabric layer comprising a main portion at one side of a stitched seam and an edge portion at the other side of the seam
  • said device comprising profiled means for diverging the main portions of the first and second layers and for moving the main portions into coplanar relationship, and for diverging the edge portions of the first and second layers and for moving the edge portions into coplanar relationship, means operative to supply moisture to the seam zone and means for ironing and heating the seam zone.
  • FIG. 1 is a plan view of a device in accordance with the invention.
  • FIGS. 2, 3, 4, 5, 6 and 7 are sections taken on the lines Il-ll, IlI--III, IV-IV, V-V, VIVI and VII- -Vll, respectively, of FIG. 1;
  • FIG. 8 shows a portion of FIG. 7 to an enlarged scale
  • FIG. 9 is a section taken on line IXIX of FIG. 7;
  • FIG. 10 is a perspective view of means for diverging portions of the fabric.
  • a base structure 1 of the assembly of the present invention forms a surface along which two superposed layers of fabric T1 and T2 are advanced stepwise in the direction of the arrow f1.
  • the assembly may be provided with means including a needle 3 for sewing together the layers of fabric T1 and T2; the needle 3 lies within the sewing Zone of the machine.
  • a suction box 5 of flattened parallel-epipedic form Downstream in the path of movement of the fabric layers T1 and T2, there is provided a suction box 5 of flattened parallel-epipedic form.
  • the box 5 is raised from the base structure 1 in order to define a gap 7 for the lower layer Tl (see FIGS. 3 and 6); the box 5 is supported on two sides on portions 1A and 1B of the base structure 1 (FIGS. 1, 5 and 6), the portion 18 being in the form of a bracket to allow the passage of the lower fabric piece T1, while the portion 1A is spaced from the sewing zone and thus from the seam by a distance corresponding to the maximum width of fabric that is likely to be used.
  • the front wall 5A of the box 5 is directed towards the seam line and at least a part of the front wall 5A is formed by a grid 53.
  • a first guide means which includes a plate 9, the plate 9 being perpendicular to the end wall.
  • the plate 9 is positioned generally midway between the upper and lower walls of the box 5 and has a longitudinal edge aligned with the front wall 5A.
  • Divergent plates 9A extend between the upper and lower surfaces of the plate 9, and the upper and lower edges of the end wall of the box 5.
  • the plate 9 is spaced from the base structure 1 by a gap 7A which communicates with the gap 7 to permit passage of the lower fabric layer T1, while the upper fabric layer T2 passes above the plate 9 and above the box 5; the two fabric layers are caused to diverge by the plates 9A (see FIG. 3).
  • first guide means which comprise the plate 9 and the plates 9a for guiding the fabric layers T1, T2, which may be considered main portions of the fabric.
  • a second guide means or plate 12 coplanar with the plate 9 and raised from the base structure 1 to form a gap 14 (FIG. 2) between the plate 12 and the base structure 1.
  • An edge portion TLl of the lower fabric layer T1 is accommodated in the gap 14, and an edge portion TL2 of the upper fabric layer T2 is located above the plate 12; the edge portions TLl and TL2 are those portions of the fabric layers which lie on the opposite side of the seam C to the main body of fabric.
  • the plate 12 is combined with an upper longitudinal wall 16 and, beyond the sewing zone, also with a corresponding lower longitudinal wall 18.
  • the walls 16 and 18 are formed, at a position slightly beyond the leading edge of the plates 9A, with two end portions 16A, 18A (see FIGS. 1, 4 and 10) which are curved gradually towards the line of the seam.
  • the end portions 16A and 18A thus reduce the width of that portion of plate 12 which projects from the walls l6, 18 towards the plate 9 and the box 5, the width being zero adjacent the front wall 5A formed by the grid 58.
  • edge portions TLl and TL2 which initially lie on opposite sides of the plate 12, are caused to diverge by the end portions 16A and 18A of the walls 16 and 18 and move towards the portions of the fabric layers T1 and T2 on the opposite side of the seam C; these portions of the fabric layers T1 and T2 are caused to diverge by the effect of the plates 9A.
  • moisture for instance in the form of steam
  • a tube 20 which discharges the steam adjacent the trailing edge of the end portions 16A and 18A of the walls 16 and 18. Moistening of the fabric is effected in front of the front wall 5A.
  • Two heated rollers 22 and 24 are arranged to press the fabric against the grid 5B.
  • the jet of steam is directed between the roller 22 and the front wall 5A.
  • the rollers 22 and 24 are urged in the direction of arrows f2 towards the front wall 5A. In this way, the fabric is ironed.
  • the rollers 22 and 24 are angularly advanced in steps synchronized with the advance of the fabric layers T1 and T2, the linear length of the advance of the rollers 22 and 24 at their peripheries being equal to the length of advance of the fabric layers T1 and T2.
  • a vacuum is created in the interior of the box 5, for example by withdrawing air through a fitting 26 (see FIGS. 1 and 5).
  • the two fabric layers with the flattened, stabilized, seam setting are discharged from the slot 7 as shown in FIG. 6.
  • the rollers are carried by movable support means including a relatively large diameter shaft, a shaft 28 for the roller 22 being shown in FIG. 7.
  • the shaft 28 is journalled in an elongate bush 30 which is supported by a cup member 32 mounted on stirrups 34.
  • the stirrups 34 (and those for the roller 24) are supported by a plate 36 through suitable connecting pins 38.
  • the plate 36 has two arms 36A which extend parallel to the direction of the arrows f2.
  • the shafts of the rollers 22 and 24 can be driven by drive means combined with means for advancing the fabric layers.
  • the arms 36A are provided with longitudinal channels (see FIGS.
  • roller means in the form of ball bear ings 42 being located in the co-operating channels.
  • the plate 36 is reciprocable by means of a fluid actuated cylinder 44, which thus effects movement of the rollers 22 and 24 towards and away from the front wall 5A of the box 5, and determines the ironing pressure of the rollers against the front wall 5A.
  • the rollers 22 and 24 are heated through their bearing systems. More particularly, as shown in FIG. 7 with reference to the roller 22, there is wound around the cup member 32 a resistance heating element 46 which heats the shaft 28.
  • a probe accommodated in a head 48 contacting the rollers 22 senses the roller temperature and acts via suitable control means to maintain the temperature substantially constant at the desired value. Transmission of heat generated by the element 46 towards the structure is reduced by the presence of the stirrups 34, the pins 38, the balls 42, and the shape of the plate 36.
  • a seam flattener apparatus for directing a pair of fabric layers past an ironing station and for ironing portions of said fabric layers, said fabric layers each including a longitudinally extending outer edge,
  • said apparatus comprising, in combination,
  • first guide means configured to dispose said main portions in a coplanar relationship relative to each other, with each of said main portions extending away from said seam in opposite directions
  • second guide means configured to dispose said edge portions in a coplanar relationship relative to each other, with each of said edge portions extending away from said seam in opposite directions and with the edge portion of each of said fabric layers overlapping the respective main portion of its corresponding fabric layer
  • said pressing and heating means include at least one heated roller rotatable in synchronism with movement of said fabric layers, means defining a surface disposed opposite said roller and adapted to have said fabric layers passed-between said defined surface and said roller, with said main portions of said fabric layers being supported 'in coplanar relationship against said surface, and means for biasing said roller toward said surface to press said coplanar edge portions of said fabric layers against said coplanar main portions thereof.
  • said moisture supplying means includes means for directing a jet of steam onto said fabric layers immediately upstream of said roller, said apparatus further comprising suction box means including walls, said suction box means configured to have said surface formed by one wall thereof, said one wall being perforated, said suction box means including means for drawing moisture containing air from said fabric layers into said suction box means, said suction box means being structured to extend from said one wall whereby said main portions of said pair of fabric layers may extend over opposite sides thereof.
  • said first guide means comprises a plate extending from said suction box means in a direction to have said seam pass generally parallel thereto, said plate being located to have said main portions of said fabric layers pass on opposite sides thereof, and a pair of inclined walls extending between said plate and said suction box means in a generally diverging relationship to separate said main portions and to direct said main portions toward said coplanar relationship.
  • said second guide means comprises plate means located to have said edge portions of said fabric layers extend on opposite sides thereof, and wall means extending along said plate means and disposed relative thereto with a configuration causing divergence of said edge portions from said plate means such that said edge portions are directed into a substantially coplanar relationship immediately before the location of said pressing means.
  • Apparatus according to claim 2 including heat transmitting means having said roller supported thereon, and electrical heat generating means mounted on said heat transmitting means, said heat transmitting means being configured to transmit the heat generated by said heating means to said roller.
