Definitions

  • the subject of the present invention is a device for sewing the point of knitted tubular manufactured products, in particular at the bottom, according to a predetermined curved seam linen.
  • the stockings are made from a tubular element knitted with the ends open and that, subsequently, one end of the element, that is to say the toe, is sewn.
  • Toe stitching is carried out with a toe closer machine comprising a plurality of tubes for supporting manufactured products, which are mounted on a carousel rotating intermittently between a first loading station, a second station for placing the sewing point according to the curve obtained, a third station where the actual sewing of the point of the manufactured product is carried out and a successive station for unloading the manufactured product with the point thus opulent.
  • document US 4192242 discloses a device comprising a belt closed in rings which, in correspondence with the positioning station of the sewing point, results with an edge in contact with one side of the point of the manufactured product to achieve the drag along a curvilinear path, in cooperation with two horizontal lateral fins of the respective support tube which are moved forward so as to bring the tip of the manufactured product outside and beyond the mouth of the tube, on an underlying movable plane rigid structure vis-à-vis which, when placed in the raised position, compresses the tissue of the tip against the fins of the tube and against the corresponding portion of belt.
  • the upper side of the fabric is interposed between the fins and the strap.
  • the fins of the tube are removed to allow the movement of the fabric of the point thus treated towards and until a sewing machine which realizes the closing: the point of the manufactured product being supported on a horizontal plane support as the tube advances to and from the sewing machine.
  • the main object of the present invention is to eliminate the aforementioned drawbacks. This result was achieved in accordance with the invention by adopting the idea of producing a device having the characteristics described in claim 1. Other characteristics are the subject of the dependent claims.
  • the advantages deriving from the present invention essentially consist in that it is possible to intervene on the fabric of the tip of the manufactured product all along its transverse extension, without the possibility of damaging it, and without altering its position before sewing. ; that a device according to the invention is relatively simple to manufacture, economical, reliable even after an extended period of exercise and can be easily mounted even on already existing sewing machines.
  • FIG. 1 shows the side view of a device according to the invention
  • fig. 2 shows the plan view of the device of FIG. 1
  • fig. 3 shows a detail of the device of FIG. 2 in the bent position of the toe of the manufactured product
  • fig. 4 shows the front view of the device of FIG. 1
  • fig. 5 shows the isolated side view of the device according to the invention
  • fig. 6 shows the diagram of the means for controlling the curvature of the blade of the device illustrated in the preceding figures.
  • a device in accordance with the invention for shaping one end of a knitted tubular element made with the two open ends, in particular the toe of a stocking invested in a tube (8) of support, according to the curved line corresponding to the seam line of the tip itself comprises at least a vertical elastic blade (1) which can be alternately positioned, on command, in a flat rest position and in a curvilinear working position , with the concavity facing downwards: said blade (1) being slaved to corresponding movement means from and to a separate sewing station, and arranged, in the working position, upstream of a sewing machine (4) and located above a corresponding horizontal plane (3) opposite which is placed the tip (5) of the manufactured product by means of two movable lateral fins of the tube (8) which tension the fabric with a clamp (100) intended to retain the tip (5) of the manufactured product outside the mouth of the tube (8) so as to place it slightly beyond said plane (3), to determine the curvature of
  • said means of movement of the elastic blade (1) comprise a motorized belt (9) closed in vertical rings to which the blade (1) is hooked so as to result with the respective free end, that is to say intended in contact with the fabric of the manufactured product, oriented towards the outside, that is to say centrifugally, relative to the belt (9).
  • the actuating motor of the aforementioned belt (9) is marked with the number (90) in the figures of the accompanying drawings. With the number (93) is marked a wheel controlled by the aforementioned motor (90), for the actuation of the belt (9).
  • Said belt (9) is advantageously of the chain type mounted on a flat support (91) whose contour is capable of constituting a sliding track for the elements (92) of the chain itself.
  • means comprising two producing cylinders (2) parallel to a horizontal axis placed on the side opposite the blade (1) relative to to the belt (9) and to which is slaved a body (12) which has a seat for a pivot (13) associated with an underlying lever (14) which is connected, on the side opposite to that of said pivot (13), to a shim (15) for supporting the blade (1).
  • the activation of the cylinders (2) determines the rotation of the levers (14) around the respective pivots (13), by effect of the action exerted on these by the bodies (12) slaved to the cylinders (2), so as to cause the corresponding deformation, that is to say the elastic curvature of the blade (1). Because of the inherent elasticity of the blade (1), the activation of the cylinders (2) in the opposite direction to the previous causes the restoration of the initial plane geometric configuration. The same function can still be performed by a single cylinder.
  • the operation of the device described above is as follows. After the pliers (100) have taken the tip (5) of the manufactured product from the lateral fins of the support tube (8) of the manufactured product for such purpose extracted, to place it in correspondence with the plane (3), the blade (1) is placed in a curved position, to compress, in such a position - and after the fins have been withdrawn, that is to say returned to the respective initial position - the tissue of the tip (5) of the product manufactured against the plane (3) which is placed in the raised position.
  • the clamp (100) releases the fabric and the blade (1) is brought back to the flat position initial, that is to say non-deformed, and provides to maintain the tip (5) of the manufactured product adhering to a horizontal plane (7) of guidance by moving it to the input section of the sewing machine (4) while the tube (8) for supporting the manufactured product is moved at the same time to and from the sewing machine (4).
  • the latter is brought back to the respective position of beginning of the cycle by means of the belt (9) - that is to say say in correspondence of the plan (3) - and the tube (8) is routed to a separate unloading station for the manufactured product, for simplicity not shown in the figures of the accompanying drawings.
  • the activation of said clamp (100) is controlled by an electrical signal produced by a sensor of the opto-electronic type already known per se, with the reading of a local characteristic of the manufactured product, such as for example the free end. of the point, a mark inserted or applied in a predetermined position of the manufactured product, a variation in density or in the type of mesh of the fabric.
  • Deactivation of the clamp (100), in the direction of tissue relaxation is obtainable, for example, by means of an electrical signal associated with the plane (3) when the latter is in the raised position.
  • the free end of the blade (1) is advantageously provided with an element linear rubber (10) intended for contact with the fabric.
