A base fabric structure and a press felt incorporating that base fabric structure, having at least one set of plied monofilament twist yarns in the cross machine direction. The base fabric structure may be a single base fabric, or it may be a base fabric assembly of more than one separately woven fabric layers, of which one, more than one, or all will have plied monofilament twist yarns in the cross machine direction.

There is disclosed a woven webbing structure, which resists interwoven yarns from coming out from the surface of the webbing due to bending, or the like. This is achieved without any significant reduction in the strength or energy absorptivity of the webbing. The webbing includes warps that each have a cored yarn and a side yarn, and wefts interwoven therein. The cored yarn is set such that the elongation percentage thereof is smaller than, or the extensional rigidity thereof is larger than, that of the side yarn, and is twisted by single twisting or the like. As a result, unevenness is formed on the surface of the cored yarn and friction between the cored yarn and other yarns, that is, the side yarn or the weft increases. The frictional force between yarns functions for resisting free movement of the cored yarn due to bending of the webbing, thereby making it possible for the cored yarn to resist coming out from the surface of the webbing.

A shaped sheet usable for the production of slabs made from a material mixture of granulated stone material and/or sand and by a binding resin includes a flat base and a peripheral frame projecting from the base for a predetermined height so as to define a seat of dimensions corresponding in plan to those of the slab to be produced. The structure of the flat base includes a first rubber layer of previously cured rubber forming a first surface which adapted to be in contact with said the material mixture and a second rubber layer of previously cured rubber, a first layer of cloth and a second layer cloth, wherein the said second cloth includes a second outwardly directed surface of the shaped sheet.

A woven fabric used as a lining in a shirt sector, consisting of fabric-forming warp and weft filaments which consist of synthetic material, wherein the weft yarn consists at least partially of crimped yarns. The finished fabric is then coated in punctiform manner with a hot sealable adhesive on the basis of copolyesters and/or low pressure polyethylene in the spot raster with a spot density of 600 to 1400 spots/inch.sup.2. The invention also comprises colored, marked and flame-resistant linings. The coating with hot sealable adhesive can be carried out in punctiform manner using all the known application technologies. It is also taken into consideration that a calendering process can be undertaken after the coating process.

The invention concerns a process for freezing an article, such as a food according to which said article is contacted with the surface of a porous support which is impregnated with a cryogenic liquid. The invention also concerns a device for freezing an article including a conveyor of porous material, which is insulated by means of an enclosure as well as means for impregnating said conveyor with a cryogenic liquid.
