Definitions

  • the present invention relates to a method and a machine for the automatic sewing of two stockings to form a pantyhose.
  • the main object of the present invention is precisely to considerably reduce the time for automatic formation of tights by using the same sewing machines as those available today.
  • Another object of the invention is to free the operator responsible for loading the correct positioning of the stockings on the forms, by automatically and quickly, but with great precision, the correct positioning, that is to say the alignment vertically of the elastic edge and the body of the two stockings before making the longitudinal cut.
  • the advantages obtained thanks to the present invention essentially consist in the fact that it is possible to drastically reduce the manufacturing time of the tights while retaining the maximum execution precision, by reducing the time of the whole cycle of operation within four seconds, which represents a result never before achieved; that it is possible to carry out double stitching by leaving the inguinal zone of the tights seamless for the application of a bellows; that it is possible to program the sewing length of each sewing machine; that it is possible to subdivide the seam into two separate stations by sewing the second portion starting from a point in the first portion already sewn; that it is possible to vertically align the elastic edge and the body of the stockings with the corresponding shapes, allowing the operator to load them without positioning and therefore faster.
  • FIG. 1 shows a schematic plan view of a carousel machine with several stations, for automatic sewing in a single station, according to the invention
  • FIG. 2 shows a detailed axonometric view of the means for the vertical alignment of the two bottoms
  • FIG. 3 shows the longitudinal sectional view of the detail in FIG, 2 with the bottoms in a possible initial position for manual loading
  • FIG. 4 shows the detailed view of FIG.
  • FIG. 5 shows the plan view of the detail of FIG. 4
  • FIG. 6 shows the detailed view of FIG. 3 with the means for aligning the elastic edges engaged on the elastic edge of the two bottoms and with the means for aligning the deactivated bodies
  • FIG. 7 shows the plan view of the detail of FIG. 6
  • FIG. 8 shows the detailed view of FIG. 3 with the two elastic edges permanently aligned vertically and with the means for aligning the bodies at the end of alignment
  • FIG. 9 shows the plan view of the detail of FIG. 8;
  • FIG. 10 shows the detailed plan view of the sewing station with the two sewing machines before sewing;
  • FIG. 11 shows the simplified side view of the detail of FIG. 10;
  • FIG. 12 shows the detailed view of FIG. 10 with the two sewing machines at the end of a continuous seam;
  • FIG. 13 shows the detailed view of the cutting means of the net chain remaining from the first seam portion;
  • FIG. 14 shows the detailed view of FIG. 10 with the two sewing machines at the end of an interrupted seam;
  • FIG. 15 shows the enlarged detailed view of the sewing interruption zone;
  • FIG. 16 shows a schematic plan view of the variant of the machine of FIG. 1 for sewing in two successive stations.
  • said vertical alignment of the two elastic edges is obtained with operational means with reciprocating horizontal movement, the outward travel of which is intended to detect the position of the first elastic edge encountered, that is to say that of the two bottoms which is each time loaded closer to the predetermined alignment position, then reaching and grasping the second elastic edge, i.e. the bottom edge which was loaded further from the predetermined alignment position, and the return stroke of which is intended to move said second elastic edge and said first elastic edge thus aligned with each other in sliding direction until they reach the predetermined alignment position.
  • the identical positioning of the body of the two bottoms on the forms is obtained with operational means with reciprocating horizontal movement, one race of which is intended to accumulate the tissue of the body on the corresponding form and the other course of which is intended to thread the body over a predetermined length from the dividing line between the body and the lower leg.
  • each of the two sewing machines performs a corresponding stitching the length of which is slightly greater than half the length of the total seam, which results in a double seam, of variable length as desired, in the middle zone, that is to say in the inguinal zone of the tights.
  • the sewing of the two portions by the two sewing machines can - in accordance with the invention - be carried out in a single processing station and therefore on the same manufactured product or differently in two consecutive processing stations, and in this case on two products manufactured separately, but always simultaneously.
  • the first sewing machine 5 sews on a portion T1 which ends before the middle of the total sewing and the second sewing machine 50 sews on a portion T2 which begins after said middle, so that the central zone, that is to say the inguinal zone of the pantyhose, is devoid of seam: this being advantageous for the successive application of a bellows.
  • the length of the double seam in the case of a continuous seam and the interval between the two seams in the case of a discontinuous seam is variable as desired by adjusting the active stroke of the two sewing machines 5.50.
  • the stockings to be treated are made with a single density fabric or in any case without difference sensitive, it is foreseen, in accordance with the invention, to insert beforehand in the stockings a mark, that is to say a thread of color different from that of the fabric and in any case likely to be detected by the sensors 41 and to be used as the positioning limit of the bottom in relation to the length of the seam to be made.
  • each of the four sensors 41 being associated with a displacement group 4 so as to be able to activate the corresponding belt 42 even separately from the belts 42 of the other groups 4.
  • This turns out to be advantageous in order to allow the dividing line 23 of each bottom to take an arrangement always perpendicular to the axis of the corresponding shape.
  • the operation is as follows. An operator - in station A of the carousel 10 - puts on by hand, at random and without positioning them, two stockings on the two forms 1; with the rotation of a step clockwise from the carousel, the shapes stop in the next station B in which the two stockings undergo the alignment of the elastic edges and the positioning of the bodies in the following manner .
  • the belt 42 of the associated group 4 and which is in contact with the edge 12 of the corresponding shape 1 with interposition of the corresponding bottom is actuated in the direction allowing thread the bottom onto the form to form an accumulation 26 of the bottom fabric and this until the sensor 41 of each bottom, after having detected the line 23 of separation between the body 22 and the leg 24 of the bottom, controls the spacing of the belt 42 of the form and its stopping.
  • the four belts 42 are again juxtaposed to the shapes and actuated in the opposite direction, that is to say scrolling of the stockings relative to the shapes, making the lines 23 move a predetermined length, but variable as desired, and at the end that they are aligned vertically in a predetermined position relative to the shapes 1 .
  • the latter controls the corresponding strap 42 so that the bottom is unthreaded to the shape necessary for said line 23 to be detected by the sensor 41; after which the belt will thread the bottom of the predetermined length to bring the line 23 into the predetermined alignment position.
  • the first sewing machine 5 sews the first portion T1 of tights and the second sewing machine 50 simultaneously sews the second portion T2 of another pantyhose.
  • the complete sewing of the pantyhose is obtained in a time of approximately half that used until today with the known pantyhose sewing machines.
