Definitions

  • the invention relates to an apparatus and a method for shaping tights.
  • the invention further relates to molded tights.
  • a first inexpensive method is to have the tights in completely unshaped, i.e. to bring the crumpled and clumped condition into a packaging and thus lead it to the sale.
  • Another method is the production of so-called half-shaped stockings.
  • the two leg sections of a pantyhose are pulled onto two U-shaped brackets or full-surface shapes and the pantyhose is subjected to a dry heat treatment, for example infrared radiation.
  • the U-shaped brackets consist of a U-shaped curved round material and have dimensions such that the leg sections of a pair of tights are spread so that a visual quality control of the two sections can be carried out.
  • the two U-brackets are aligned so that both U-bracket levels lie in one plane, and are spaced apart from one another in such a way that the pants section of the pantyhose is also spread, in particular in the gusset area, so that the visual quality control is also possible this critical gusset area, in which there are usually several seams, can be carried out.
  • the legs of the U-shaped bracket run straight and merge into one another via a semicircular curve on the closed bottom of the U. There is therefore no anatomical foot or calf formation.
  • Another method of shaping is the so-called full shaping of the tights.
  • the tights are stretched onto shapes, namely flat shapes, i.e. the tights material is in full contact with the shape.
  • the ladies' tights which are pulled up and spread in this way, are subjected to steam shaping, at temperatures of approximately 120 to 130 ° C., in which case steam is pressurized to a pressure of approximately 3 bar.
  • a drying process then takes place while still in the drawn state. After pulling off the shape, the tights have exactly the shape or the outer contour of the shape on which it was drawn up and has been subjected to a full molding cycle.
  • Another known shape for full shaping is designed such that the outer contour of the leg part corresponds to the shape of a planar projection of a side view of a human leg.
  • the shape known from this has a rectilinear contour in the area of the shin which merges into an angled foot contour at an angle of approximately 160 ° C. In the area of the heel, the foot part protrudes beyond the rear contour of the leg, and a calf area can be defined in the further course of the rear contour.
  • the contour is thus shaped by a relatively straight leg section, at one end of which there is an angled foot section.
  • This shape with the contour of a projection of a side view of a human leg with an angled foot section now has the disadvantage that it is very difficult to apply a stocking to this angled shape and to pull it off again. This is particularly difficult in the case of longer stockings, and can be accomplished only with great effort in the case of tights, with the risk that the tights will be overstretched and thereby damaged.
  • EP-A-0 518 184 proposes to form the leg shape in two parts, namely an actual leg part with a foot part connected to it in an articulated manner.
  • the foot part can be pivoted via an actuating mechanism so that the foot part is aligned in the direction of the longitudinal axis of the leg.
  • a first disadvantage is that the shape as such is designed to be very complex, and that the control elements and the pivot axis represent points which can damage the sensitive material of the women's tights.
  • the mechanically moving parts such as rocker arms, axle joints are exposed to considerable loads in the harsh conditions of full molding (120 to 130 ° C, steam with pressure 3 bar).
  • a complex control is necessary to the foot parts with the puller and puller synchronize a fully automatic opening and closing of the hosiery. That is, a control mechanism must be provided which ensures that the foot part is aligned in the longitudinal direction of the leg for pulling on and off, and is pivoted after pulling up so that the desired angled position of the foot part is achieved.
  • This construction also has the considerable disadvantage that visual quality control is extremely difficult to carry out. Since the two leg parts of the shape must run parallel to one another in order to be anatomically correct, a viewer can, provided the shape is presented to them from the side, only inspect a single outer side directly. In this position, the two leg parts of the form lie congruently one behind the other, so that, for example, only one right outer side of the leg of a lateral projection of a leg can be seen. Neither the inner side of this leg, let alone the side of the leg behind it, can be inspected directly, so that complex mirror constructions or intensive head movements of the viewer are necessary.
  • a leg shape would result, as is known, for example, from the leg position in the "Charly Chaplin films", in which, in a front view of a person, the side surfaces of the legs which are angled to the left or right are visible.
  • This shape is intended to simplify the putting on and taking off of the individual stockings, since it is no longer necessary to pull on a foot part which is angled laterally with respect to the rest of the stocking.
  • the invention has for its object to overcome the disadvantages of the prior art in the full shaping of hosiery with an anatomical shape of the leg contour and to provide a device and a method for the full shaping of tights, with a simple structure and a possibility for semi or fully automatic Handling as well as for a simple visual error control. Furthermore, appropriately shaped tights are to be specified.
  • this object is achieved by a device for shaping tights, with two flat shapes arranged side by side, the contour of which corresponds to a flat projection of a front view of a human leg, the shapes being orientable, at least for pulling off, into a position parallel to one another.
  • the flat projection of a front view of a human leg results in a contour which, in contrast to a side view, has no angled foot region.
  • a projection of a front view in the area of the toe, the area of the toes and the area of the ankle is no wider than the foot in the area of a calf or thigh. This results in a shape which has the desired anatomically curved contour line, in particular in the area of the foot, without any bends which prevent a pulling or pulling operation.
  • a pair of tights can be put on the two forms by hand or automatically with a corresponding elevator device, for example with a pre-gathering device according to EP-A-0534 188.
  • the tights can be pulled off from two adjacent forms which are oriented parallel to one another, for example by means of lateral pulling strips which are approached to the forms from both sides.
  • the tights can be removed according to a further development of the invention, for example by means of pull-off elements which can be pressed in pairs in a controlled manner onto the side longitudinal edges of the shapes are and are movable in the longitudinal direction of the molds.
  • the contour is mirror-symmetrical to the central longitudinal axis of the leg and is adapted to the proportions of the anatomical contour.
  • This measure has the considerable advantage that identical shapes can be used for both a left and a right leg. Due to the flexibility of the material of hosiery is in shape with the contour according to the invention a flat projection of a front view is irrelevant whether in the tiptoe area the anatomically somewhat protruding area of the big toe is to the left or right of the central longitudinal axis in this projection, so that an approximately semicircular contour is equally well suited to a left or right foot to record.
  • the feature "adapted to the proportions of the anatomical contour" is to be understood in such a way that the outer contour is chosen such that an appropriate amount of material of the tights is sufficiently tensioned or spread over the shape at the corresponding points in the foot area so that in the case of full shaping, a good heat exchange can take place between the shape and the material lying flat against it, which then leads to good shaping with a smooth outer surface, but at the same time there is sufficient material to cover the anatomical areas protruding from the flat front projection, e.g. B. instep or heel, later to cover evenly with tights on.
  • the anatomical curves e.g.
  • the shape can be designed as a flat element.
  • This measure which is known per se, has the advantage that particularly good smoothing of the material is achieved, particularly in the case of steam shaping.
  • the shapes consist of rod-shaped material that is bent according to the desired contour. Although this produces a somewhat less smooth surface, particularly in the case of steam shaping, this type of design of the molds offers considerable advantages, since on the one hand there is a greater rigidity of the molds as a result of a higher section modulus and on the other hand the pulling off the tights from the shapes can easily be done by side-moving tapes.
  • an opening is provided in the shape of the heel.
  • a pair of tights is formed on such shapes with openings in the area of the heels, then areas in the heel area and, of course, in the area of the instep of the feet, material-rich areas are created, which are less tightly tensioned or smoothed, so that these areas are easier to arch both Adjust the foot in the area of the heel as well as the curvature in the area of the instep when tightening and then take on a smooth, taut appearance.
  • This variant is particularly preferable for tights in which the heels are not formed anyway.
  • a lowered hole is only present on one side of the mold in the heel region.
  • This measure has the advantage that an unformed, material-rich area of the tights is formed only on one side of the shape, for example only on the side of the heel.
  • a curvature is provided on the shape in the area of the heel.
  • the curvature of the heel represents a relatively slight elevation from the projection plane, so that an upward or downward movement is not disadvantageously impeded by an effect corresponding to the anatomy of a heel curvature.
  • the fabric Due to the curvature of the shape, the fabric is tight and can then be inspected visually for imperfections in the stitch pattern or seams in the heel area.
  • the curvature is designed as an area printed out from a plane of the shape.
  • the flat shape for forming the hosiery can be easily produced by a combined punching / pressing process.
  • the two adjacent forms can either be aligned with their flat sides one behind the other in one plane, for which purpose a folding or other movement process is then required before the tights are removed from the forms, in order to arrange the two forms in a parallel arrangement bring to.
  • a movement device for moving at least one shape with respect to the other shape which enables the at least one shape to be moved into an arrangement that is essentially parallel to the other shape, but offset laterally relative to the other shape.
  • this feature of the invention can also be used independently with conventional shapes, for example with U-shaped flat shapes or U-shaped shapes made of curved round material.
  • the movement device is designed as a swivel device, the swivel axis of which is arranged off-center between the two shapes.
  • the tights can first be pulled onto the two flat shapes aligned in one plane, visually checked and shaped in this position and then, before pulling off, can be brought into the desired parallel but laterally offset position simply by pivoting the two shapes towards one another.
  • the movement device in which the pantyhose is drawn from the outset into shapes oriented parallel to one another, can be designed as a displacement device for displacing at least one shape with respect to the other shape oriented parallel thereto.
  • At least one pull-off element is provided on each of the longitudinal sides of the shapes, which can be pressed in a controlled manner onto the lateral longitudinal edges of the shapes and which can be moved in the longitudinal direction of the molds.
  • the trigger elements follow the curves on the side longitudinal edges of the molds, so that the tights are automatically pulled off the molds without being overused locally.
  • the trigger elements can be pressed against the side longitudinal edges of the molds via fluid cylinders.
  • the fluid cylinders are preferably connectable to a pressure source for generating a largely constant contact pressure.
  • the molds consist of rod-shaped curved material, as already mentioned above, pull-off tapes can be pressed onto the molds from both sides for pulling off the tights.
  • a carousel which can be rotated about its vertical axis and on which a plurality of molds are arranged in pairs, a plurality of treatment stations being arranged along the carousel, between which the shapes can be moved by rotating the carousel.
  • At least one feed station, one clamping station, one steam forming station, one drying station and one take-off station are preferably provided in order to enable the device to operate fully automatically.
  • the object of the invention is achieved by a method with the following steps. Pulling up a pair of tights with their two legs on two adjacent flat shapes, the contours of which are each a flat projection correspond to a front view of a human leg. Exposing the pantyhose to heat to form the pantyhose on the molds and peeling off the pantyhose from the molds.
  • the tights are preferably shaped by the action of steam and then dried.
  • the leg sections, the foot sections and the pants section are formed in one plane, as a result of which pleats form along the side longitudinal edges of the legs.
  • the flat shapes are aligned parallel to one another and the tights are then pulled off the shapes and folded in such a way that a curved contour can be seen from the outside in the area of the foot sections and / or the calf.
  • This measure has the advantage that the high-quality shaping of the tights can be recognized immediately in the sales packaging on the basis of the curved contour.
  • At least one of the shapes is pivoted with respect to the other shape, in order to convert the two shapes into one with its two to bring flat sides parallel to each other, but laterally offset from each other.
  • the tights are preferably pulled laterally offset from one another from the molds and folded with overlapping legs offset laterally relative to one another and placed in packaging.

Abstract

Dispositif et procédé pour la mise en forme de collants consistant à tendre les collants sur deux formes (242, 244) disposées l'une à côté de l'autre, dont le profil correspond à une projection plane de la vue de face d'une jambe, lesdites formes (242, 244) pouvant être ajustées, au moins lors de l'enlèvement, suivant une position où elles sont parallèles entre elles. Les collants sont tendus sur les formes (242, 244), de préférence suivant des positions alignées les unes derrère les autres, puis traités par la chaleur, de préférence à la vapeur, afin qu'ils prennent la forme désirée, puis finalement retirés desdites formes (242, 244). On obtient ainsi un collant mis en forme, dont la jambe est adaptée au profil d'une projection plane de la vue de face d'une jambe, ce qui, d'une part, permet d'avoir une meilleure présentation du produit définitivement mis en forme et, d'autre part, facilite considérablement la pose et l'enlèvement dudit collant.
