Abstract

The present invention relates to a method for making underpants, panties and the like, comprising the steps of providing a semi-fished article of manufacture comprising a flat layer of an elasticized fabric, overlapping, at the edge ends, a plastics material finishing strip and joining to one another the cross portions arranged at the opposite base edges to provide an underpants or the like article.

Description

Production procedure for shorts, panties and similar items.

Background of the invention

The present invention is related to a procedure for making briefs, panties, slips and similar items. as well as underpants, panties and Slips and similar items made by it.

As is known, for making briefs, panties and slips and similar items, especially for women, the tissue parts intended for the manufacture of the aforementioned articles usually join, that is, the parties of fabric comprise elements of tissue of different types, such such as cords, stretch fabrics, ribbons, etc. that are joined by seams, giving this bike the items the desired shape.

It should be clear that this procedure It involves several problems, the main one being the high cost of tailoring since sewing work is done fundamentally at hand.

Another problem is that seams inevitably create an area that stands out and that can irritate the user's skin, mainly in the upper area of the leg and inside of the thigh.

Another problem presented by solutions according to the prior art is the one that possible reinforcements or interweaves, that they are usually arranged in the groin area, require a subsequent process that negatively influences the cost of the item ready made

EP 1 033084 describes an article of preparation and a procedure for its preparation in accordance with the preambles of claims 15 and 1, respectively.

Summary of the Invention

The object of the invention consists, therefore therefore, in solving the aforementioned problems providing a procedure for making underpants, panties, slips, etc. that allows to completely eliminate processes or Sewing phases and get an item that fits perfectly to the user's body.

Within the scope of the aforementioned objective, One of the main goals of this invention is to provide these briefs or slips of reinforcement zones or with interlinings, taking into account the user's requirements.

The mentioned results are achieved by the execution of a high frequency sewing process or thermofusion to join the woven parts of synthetic material or parts of fabric previously coated or spread above, to which is applied a material that melts to heat.

Alternatively, layers or tapes of hot melt material are arranged between the parts or layers of fabric that allow, through a thermofusion process or a high frequency fusion process, to fix the peripheral area of the fabric or layer and / or join them together. no need to sew to shape the items
the.

Another object of the present invention is to provide briefs, panties or slips that, due to their specially designed structural features, offer a great reliability and safety in the process.

Another purpose of the present invention It consists of presenting a procedure that allows the preparation of briefs, briefs, panties, etc. using elements and materials Easy to get and with a very low cost.

According to one of the aspects of the present invention, the purpose and the aforementioned objectives, as well as any other objective, which will be more evident in The description that follows is achieved through a procedure for making briefs, panties, slips and other items similar according to claim 1.

The edges of the peripheral part of the article and the joining of the edges to be joined is done by applying of a high frequency thermofusion process.

In case of synthetic fibers and / or fibers resin coated, the thermofusion process high mentioned frequency results in a thermofusion of the fibers that they must be fixed by their peripheral edges or joined together.

Brief description of the drawings

Other features and advantages of this invention will become more patent in the following and detailed description of a preferred embodiment variant, although not exclusive, of the procedure for making underpants, panties and similar items, represented by means of an example illustrative, but not limiting, in the accompanying drawings. These show in the

Figure 1 a schematic representation of the semi-finished article object of the invention and, in addition, in explosion, a reinforcing element for the
same;

Figure 2 another schematic view of some finished briefs;

Figure 3 on a larger scale, the union between crossed parts of the opposite basic edges arranged in a lateral zone

Description of preferred embodiments

With respect to the reference numbers of the figures mentioned above, the method according to the invention for the manufacture of briefs, panties, slips and similar items it comprises a step in which a semiproduct 1 is made available manufactured from an elastic fabric that has fundamentally, preferably, the shape of an hourglass.

The fabric layer 1 is advantageously obtained by cutting by stamping a piece of fabric, or by manual or mechanical cutting through said piece of fabric.

Layer 1, which is fundamentally shaped of an hourglass, it comprises a front part 2 that leaves narrowing towards a central part 3 to widen again then back to the back.

The front 2 and the back 4 they end in basic edges 5 and 6 that, at their ends, join the respective cross-sections 7 and 8 delimiting practically the rear part formed in the center of layer 1.

The edge of the semi-finished product comprising layer 1 is overlapped by a sizing strip 10 of material plastic, which can be made of polyurethane or other materials synthetic, intended to be intimately linked to the product semi-finished

In this regard it should be noted that layer 1 It could also be cut after applying the layer of sizing that includes said strip 10.

In addition, the sizing strip 10 can be made spreading an adhesive material that melts hot or by means of another appropriate analogous procedure to get the Plastic strip sticks to the fabric.

The plastic material to be used in particular, and its specific characteristics depend on the need to provide sturdy edges that, in any case, should Have the desired softness.

For the finish of the briefs and panties it is it is necessary to join the crossed parts 7 and 8 together they practically seal each other by direct use of the finishing layer 10, or possibly interposing a strip of material that melts in heat and allows to carry out the operation sealing.

With the brief in finishing situation, before carrying out the cross-linking process 7 and 8, a reinforcement layer 20 that overlaps the flat area 3 is applied which corresponds practically to the groin area, providing thus a reinforcement element of easy application without Need for sewing processes to shape the article.

In this regard it becomes clear that the underwear, object of the invention, in addition to allowing its One-piece construction and by thermofusion of the edges and flaps to be joined, it can also be made from two parts separated by a dashed line (a), as shown in the Figure 1.

In this case, contiguous parts or flaps located next to said dashed line (a) are sealed by thermofusion

The article object of the invention is also You can make from an hourglass-shaped fabric, as depicted in figure 1.

Alternatively, the body of the article is can be made from different separate flat flaps and joined together by a high frequency fusion process or a thermofusion process.

The mentioned article can be made also properly cutting the edges and closing by fusion a elastic tubular part of fabric.

The article obtained in this way offers the great advantage of being able to adapt perfectly to the user's body, what is achieved thanks to very soft edges, practically lacking in thickness, so they do not irritate the user's skin.

Another important aspect of the invention consists of in the possibility of providing an excellent level of comfort and extraordinarily support the user's body thanks to the ability of the ready-made article to adapt to the body.

The invention, as described, allows modifications and variations provided that the essence of the invention.

In addition, all structural details can be replaced by other equivalent technical elements.

For the implementation of the invention, you can use any material, size and shape, always in Dependence on needs.
