Description

[0036] Further advantages and expedient embodiments can be learned from the additional claims the figure description and the drawings. The figures show:

[0037] FIG. 1 shows a schematic view of a brassiere whose support is made of a composite of elastomer which is applied to a fabric layer, and reinforcement material.

[0038] FIG. 2 shows a side view of the combination of elastomer and reinforcement material in various stages of production.

[0039] FIG. 3 shows a top view of the combination of elastomer and reinforcement material.

[0040] In the figures, identical components are provided with the same reference numerals.

[0041] FIG. 1 shows schematically a brassiere as a garment 1 comprising one or more layers of fabric 2 and is encased in the rim region by an elastomer layer 4. The fabric layer 2 or the fabric layers have before cutting for example a rectangular basic format 3, within which the elastomer is applied in the track-like layers 4 in such a manner that the rim contour of the brassiere is formed. The elastomer layer 4 has a width of for example 2 mm to 20 mm. After the elastomer dries, the cutting is done by cutting the track-like elastomer layer 4 within the rim contour.

[0042] The supports 5 are also formed by an elastomer layer 4 forming the rim contour. However, in the area of the support 5 is introduced a reinforcement material 6 in the elastomer (FIG. 2, 3), which gives the supports 5 a significantly higher tensile strength. The reinforcement material 6 in particular consists of a plastic material, such as PLA or ABS, and is completely enveloped by the elastomer material.

[0043] FIG. 2 shows three different steps in the manufacture of the support 5 from the combination of elastomer layer 4 and reinforcement material 6. As can be recognized in the left picture of FIG. 2, in a first step, elastomer layer 4 is first applied to the fabric layer 2. To this end, the elastomer is advantageously heated so that the elastomer becomes deformable, in particular spreadable.

[0044] In a second step, which is shown in the middle picture of FIG. 2, subsequently the reinforcement material 6 is applied in liquid or at least soft, deformable state onto the first elastomer layer 4a. The application of the plastic material is done in one layer or in several layers, for example using a 3-D printing head, where it is also possible to apply the plastic material, for example, using a spray gun or a heated nozzle. The reinforcement material 6 has a relatively high temperature, for example at least 180 C. to ensure that the reinforcement material is in a liquid or at least soft, deformable state. As indicated in the figures, the reinforcement material 6 can be optionally applied in serpentine shape, namely both perpendicular to the plane of the fabric layer 2 and within the plane of the fabric layer 2 and transverse to the longitudinal extension of the support 5.

[0045] In a third, subsequent step, which is shown in the right picture of FIG. 2, a second, upper elastomer layer 4b is applied to the lower elastomer layer 4a, which completely envelops the reinforcement material 6. The application of the second elastomer layer 4b is preferably carried out after hardening of the reinforcement material 6.

[0046] In the left picture of FIG. 2 are shown two nozzles 7, 8, by which the elastomer layer 4 and the reinforcement material 6 are applied to the fabric layer 2. The nozzles 7, 8 can be adjusted by an adjustment mechanism in all three spatial directions and take up any position over the fabric layer. During the application of the elastomer layers 4a and 4b by the nozzle 7 and the reinforcement material 6 by the nozzle 8, the nozzles are moved along the intended track over the fabric layer 2; the elastomer material or the reinforcement material exit from the respective nozzle, and the discharge quantity of the elastomer or reinforcement material is controlled depending on the current nozzle position.

[0047] The position adjustment of each nozzle 7, 8 as well as the quantity of the reinforcement or elastomer material exiting through the respective nozzle 7, 8 is done by means of control signals of a control unit 9, wherein the control signals are generated on the basis of a digital template.

[0048] FIG. 3 shows the top view of the support 5 with the reinforcement material 6 embedded within the elastomer, which is spaced from the lateral edgesseen across the longitudinal extent of the reinforcement material 6.

[0049] Alternatively to the illustrated serpentine-shaped embodiment of the reinforcement material 6 is also possible a straight or a curved, possibly a buckled execution of the reinforcement material 6. Preferably, the course of the reinforcement material 6 follows the course of the elastomer layer 4. It can be advantageous, to connect the reinforcement material 6 directly in the region of one end of the fabric layer, for example by mechanical means such as by sewing, to create a firm connection between the reinforcement material 6 and the fabric layer 2.
