In the construction of Figs. 1 and 2 the layers of fcellular rubber are alternated by and Vadhered to layers of woven fabric IU,y I0. The fabric layers, being porous,` permit rapid evaporation of cleaning fluid from them, vespecially when. as shown, the pad as a Whole is formed with la multiplicity of punched through apertures I 2, |'2 connecting local areas of the fabric with 'the'outer atmosphere. The use of fabric `insertions is optional, as shown in Figure 3, Where the layers vof cellular closed-cell rubber are directly adhered to one another.

Also, having good permanency of dimensions,
and partially or fully vulcanized in flat sheet form of considerable thickness and the individual pieces can then be cut from the sheet by splitting l and suitably skiving at their margins.
For greater facility and accuracy of skiving,
'each cellular layer, alone or in association with one or more other layers of the cellular material the fabric layers give permanency of shape to the pad as a whole, and the two outer plies of fabric, covering the edges of the inner plies, provide a smooth surface and a good texture for the upper and lower faces of the pad and they can be extended, as shown, beyond the cellular layers,
along the curved, thin edge of the pad, to pro- Y,
vide a sewing margin I3 for ready incorporation of the pad in a garment. The number of fabric plies can be limited to two, one on each outer surface.
. The majority of the known methods for the production of closed-cell, cellular rubber are based on a two-stage process: (1) the rubber is compounded with suitable vulcanizing ingredients, antioxidants, pigments and a blowing agent and pre-vulcanized in a mold or frame the volume of which corresponds exactly to the volume of the rubber compound. In this manner the gasier or blowing' agent is caused to decompose but the article, unlike in the method of making chemically blown sponge, is not caused or permitted to expand during cure. When the process of prevulcanization is accomplished the mold is opened and the pre-cured blank pops out and expands to several times the size of the mold, under the action of the relieved but still confined gas. Due to the fact that the rubber is pre-vulcanized, the 'expansion of the rubber from the size of the precure mold to the size of the pre-cured blank takes place without rupture of the cell-walls, and without rendering the structure inter-communicating. (2) The second step of the process consists in transferring the blank to a larger, final-cure mold and finally vulcanizing it substantially without further expansion over and above the spontaneous and instantaneous expansion which took place upon release of the blank from the pre-cure mold.
In one form of my invention the cellular layers are cut from such partially vulcanized or pre-vulcanized and expanded -material and. the individual pieces are then built up, if desired, with-*the or of fabric, can be preliminarily frozen and then operated upon while in a frozen condition.
Because of the closed-cell character of the material, the distortion of it, as in ironing or pressing the garment, does not cause the gas within the cells to escape, but only compresses it, and when the distorting force is removed the gas expands and restores the individual cells, and consequently the pad as awhole, totheir original shapes.
, Thisl effect is especially good when the sponge material is formed by a known procedure ,such as to leave the cells filled with a gas, such as nitrogen, which is not highly subject to diffusion.
Even though the forming of the Ventilating holes I2 by cutting them with a die and punch opens some of the cells at the cut, the adjacent cells remain closed and consequently the cutting does not result in substantially increasing the permeability of the cellular material.
The holes can be die-cut concurrently with the die-cutting-of the pieces from a stack of sheets of the stock.
Alternatively the Ventilating holes can be formed by mold pins in the mold-Vulcanizing of the pad. l
The usual compoundingl ingredients, including reinforcing fibrous materials, can be employed.
The pad shown in Fig. 3 is built up, with the use of a suitable adhesive, of a set of pieces of cellular stock suitably preformed either by cutting and skiving or bymolding and the ventilatving holes I2a., I Za, similarly spaced in all of the plies, provide' Ventilating passages extending all of the way from the inner face to the outer face Vof the pad. This pad is adapted to be enclosed vwithin a fabric cover, or to be adhered to fabric- :fabric plies, and with the use of a suitable slvent' resistant' adhesive, to approximately thev final .shape of the pad, on a simple form, which can --be of wood, cast-iron or aluminum and consequently inexpensive, and the pad as a whole can be given its final shaping and vulcanizing in a suitable mold.
Alternatively the pad can be built up (and the plies adhered to each other with a solvent-resistant cement) from material which has been given the final cure, and in such case the nal molding can be omitted.
For greater softness and adaptability as to shape the plies can be adhered to each other in local areas only, as at the center or at spots along the middle line, and not throughout their extent.
Two of the pads can be built up and mold-vulcanized or otherwise formed as a single unit and thencut apart in the plane of their thicker ends, each half of the unit then being a pad such as is shown in Figs. 1 and 2.
Alternatively the material can be made cellular surface layers, for its incorporation in a garment by sewing. Y A
Fig. 4` shows a similar pad without Ventilating holes, the pad having Ventilating and sewable cover layers I4, I5 of bonded ber, such as wool, which is of open-mesh form in all of the three dimensions. The inner plies are adapted to resist penetration of solvent as above-described and the open-mesh fiber, bonded with a solvent-resistant substance such as those above mentioned, is adapted to permit solvent to drain and evapcrate from it rapidly.
In the pad of Fig.`5 the inner plies I6, I6 are of the bonded fiber and are protected from solvent by covering sheets I7, I8, IS of the closedcell sponge material.
Thisis a desirable type of pad for the utilization of trimmings and scraps of either of the materials, which can be cut into small pieces and in random arrangement treated, as by tumbling, with a suitable adhesive and pressed into sheet form, and preferably vulcanized in such form. Suitably shaped pieces are then made from the sheet and are used preferably for the inner plies I5, I6 of the pad, with the protection of the covering sheets.
In Fig. 6 a breast pad is shown as being made of inner layers 2G, 2i! of the open-mesh bonded liber above described and cover layers 2I, 22 of the s ame material, with the exception of a nipple portion 23, which is made ofthe closed-cell, cel
lular, solvent-resistant material because the bonded fiber is not so well adapted for detail mold-shaping, and because the cellular material provides more appropriate characteristics.
Preferably the. nipple portion 23 is first made cellular and given its shape in a different mold and then built into the structure as shown, the structure first being assembled, with the use of a suitable adhesive, upon a suitably contoured form, and then given, and set in, its nal shape by heating and molding it in a mold comprising sections such as the mold sections 24, 25.
Preferably the nipple member is formed with a relatively wide base portion 23a having the same thickness as a ply of the bonded fiber and underlying and thus interlocked with the cover ply 22, the nipple itself extending through a hole in that ply, as shown.
Each of these embodiments provides a pad having some or all of the desirable characteristics set out in the above statement of objects.
As an alternative to giving the plies their thinned down form at their margins by preliminary mold-shaping or skiving they can be assembled with their full-thickness margins in stepped relation and the steps can be partially or completely smoothed out in the final molding, or they can be filled in by spraying the built up pad with cotton or other ock mixed with a suitable adhesive.
As an adhesive for this purpose, or for bonding the fibers, or for joining the plies of the pad, a good substance is gelatine plasticized with glycerin and hardened with formalin, as it is nonsoluble in water, has a good bonding quality, is resistant to commercial dry-cleaning iiuids, and is not unduly afected by heat.
Further modifications are possible without departure from the scope of the invention as defined by the appended claims.
