PATENT I oFFlcE C(gNSTI'I'UTIbN AND MANUFACTURE OF TUFFING AND PADDING PIECES FOR GARIHENTS OR THE LIKE Francois C, Alf ortville; France Application April 21, 1937, Serial No. 138,246

- In France April 27, 1936 2 Claims. (01. 223-57) The present invention relates to constitutig and manufacture of stufiing and padding pi particularly shoulder-pieces for garments.

In fact such pieces are frequently used in 5 clothing making either to correct figure imper fections or, according to exigency of fashion, to increase the elegance of garments. Besides these stuiiing and padding pieces avoid cavities which would rapidly put the vestment out ofs' hape.

Thus these pieces are used for two purposes: to

rectify the shape and to maintain it.

Mostly, tailors make up, according to requirements, shoulder-pieces and other stufilng pieces from sheets of cloth or cotton-wool or like material but this making-up is long and expensive.

Several standard shoulder-pieces. of different sizes have been manufactured. Most of these shoulder-pieces comprise sheets of cloth and/or cotton-wool sewn together. They lack flexibility,

g elasticity and they sag rapidly; consequently their shape is spoiled and the garment comes out of form.

It has been proposed to make such stuffing and padding pieces by means of horse-hair united by a binding material, as rubber, and then to shape them.

The pieces made in that manner give better results than the first-mentioned ones but they present somedrawbacks:

The seam of the shoulder-pieces on the garment makes a visibl and unpleasant trace, and in the long run the stuffing-piece sags.

The hair-ends, which are not easily joined with the surface of shoulder-piece, get straight again, pass through the lining of the garment and they prick the wearer in an unpleasant manner.

It has been attempted to make up stuffing and padding pieces of sponge rubber, but their shaping is so difiicult and so expensive that hitherto they could only be made fiat. In that state they cannot suit the shape of the garment without altering the figure.

The present invention has for its purpose to obviate the aforesaid drawbacks and it provides to that end the constitution and manufacture 'of stuffing and padding pieces for clothes or the like, so as to obtain flexible, elastic, undeformable and light pieces. a

The stuffing and padding pieces in conformity with the invention comprise a core formed with entangled long and resisting fibres impregnated with a binding material such as glue, gelatine, resin, a solution, suspension or dispersion of rubber, latex, vulcanized latex and the like and this core is entirely covered by a wrapper of cloth,

linen, felt, paper or other suitable material, the

inner face of which preferably receives a coating which may be an adhesive substance.

' In order to obtain such stufling and padding pieces, fibres in a suitable quantity are put at 6 first in a preliminary form, and are impregnated with the binding material, either by immersion or by spraying and this mass is introduced in a preliminary mold, the shells of which are pressed together.

Preferably the engagement of both members of the mold takes place only at the edges of the stufling piece to be made. Thus these edges are made thinner by the pressure exerted on both shells and the material in excess is cut off. More- 15 over the clipping out operation could be made by hand.

The sheet used as wrapper of the fibrous core is divided into two leaves of suitable size, 1. e., corresponding respectively to the inner face and to 20 the outer face of the stuffing piece. It is however recommended that the size of the leaves be slightly larger than that of the faces of the fibrous bodies, so as to render possible a perfect pasting on the edges. 25

Both leaves are coated with adhesive material and shaped in mold; of suitable configuration. The shaped leaves are put on the fibrous mass and the whole is introduced in thefinal mold which presses the edges and cuts off the excess of 30 material.

The compression is preferably exerted with action of heat on the whole surface of piece and consequently, not only the fibrous mass sticks to the wrapper and is protected against pressing, but 35 the ends of fibres are fixed and cannot pierce the wrapper.

After a stay of suitable duration in the mold under pressure, the excess of material is cut off by hand at the edges and the piece is ready for 4 'use.

A modification of the operation would consist of enveloping by hand the fibrous mass in both leaves of the wrapper and compressing it as hereinbefore explained. 45

Agglomeration of the fibrous mass must be made so as to avoid any tendency of this mass to sink either under action of movements of the wearer or under action of the iron or ironing machine. 50

For this purpose it is recommended that the binding material be without any adhesive power not only at the ordinary temperature but also at the ironing temperature.

When a. solution or a suspension or a disper- 55 siun of rubber is used. there are incorporated therein products causing a quick vulcanizing at low temperature. It is feasible also to impregnate or to sprinkl the fibrous mass with anti-adhesive products.

The annexed drawing illustrates, by way of example, a form of the invention.

Fig. 1 shows a shoulder-piece in conformity with the invention, some parts being broken.

Fig. 2 shows a section of a mold arranged to make such a shoulder-piece.

Fig.3 shows the same mold open. It is seen on Fig. 1 that the shoulder-piece (as I all stuffing or padding pieces in conformity with the invention) comprises a core ll formed with agglomerated fibres and covered on its inner and outer faces with a wrapper II in fabric or other sheet material.

The core II and the wrapper H are atvfirst made up so as to have the form of a'shoulderpiece.

To obtain the final configuration it is recommended to use a mold of the type shown in Figs. 2 and 3, i. e., comprising two parts: a concave member I! disposed on a base I! and a convex member ll attached to a lever ll pivoted at I! on the base I 8.

The shell-or concave member I! of the mold lays on a movable plate I. engaged in the base ll. In a chamber 2| under this plate, a fluid under pressure (air or water) may be introduced either directly or in a deformable bag, so as to raise the plate I! and to bring the members I! and I4 together.

Thedrawing shows the configuration of members l2 and I. It is easy to remove these mem: bers and to change them for others, if the ma: chine is to be used to make pieces of different s pe. j..

The molding operation of a padding piece is made as follows:

The whole comprising the fibrous mass Ill and the two sheets ll of the wrapper is, after a preliminary making-up, introduced in the shell I2 of the mold. The lever I5 is put down and its book ll engages the yoke II. The plug ll enters the shell I! and is laid on the piece to be molded. Then the fluid under pressure is introduced into the chamber 2., so as to raise the shell I! of the mold and to compress strongly the padding piece l0, ll.

It is recommended to fulfill'this o eration with .ofcfibres or a creasing of the wrapp rintervention of heat.

As the raise of the shell I2 is made regularly any displacing or creasing is avoided.

The molding operation hereinbefore described might be made with plates bearing several molds which are tightened up simultaneously, but it would be, in that case, necessary to afford great care and attention, so as to avoid a turning up Therefore, it is preferable to use each mold separately; that permits a better control of the work and ensures obtention of thin and regular edges for the finished articles.

and

having surfaces slightly larger than those of the upper and lower faces of the fibrous body,'with adhesive on the applicatory surface, contouring and bending said sheets by compression in a mold to a shape identical with that of the fibrous body; applying the coated face of each sheet to the cor responding portion of said 'fibrous body, and finally compressing the assembly in such a man"-;

her as to cause the two sheets to adhere to the fibrous body and to cause the joined edges of these'sheets to adhere together along the periphery of the fibrous body.

2. A method for fabricating a padding member adapted for use in clothing and embodying a fibrous body, suitably shaped and covered with a casing, comprising coating two sheets of fabric. having surfaces slightly larger than those of the'upper and lower faces of the fibrous body, with adhesive on the applicatory surface, contouring and bending said sheets by compression in a mold to a shape identical with that of the fibrous body, applying the coated face of each sheet to the corresponding portion of said fibrous body, and finally compressing and subjecting the assembly to the action of heat so as to cause, the two sheets to adhere to the fibrous body and to unite the joined edges of these-sheets together along the periphery of the fibrous body.
