Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. The polymeric material is then at least partially solidified. The soluble material is then removed such as by solvent washing to thereby produce desired porous articles. Also described are systems for performing the various processes.

A fastener part consisting of at least one planar substrate part (10), on one side of which a plurality of mushroom-head-like fastener elements are arranged, each of which, as an integral part of the substrate part (10), has a solid stem part (17) formed in the manner of a rotational hyperboloid and extending along a longitudinal axis, wherein to the free end of said stem part (17) a head part (16) adjoins, the edge regions of which form hooking possibilities and project at least partially beyond the stem part (17), and wherein said head part (16) has a crater-like depression (20) on its upper side, characterized in that a plurality of further crater-like depressions (23) is incorporated into the further side (22) of the substrate part (10), opposite to the fastener elements, in that both crater-like depressions (20, 23) of at least some of the fastener elements extend concentrically or mainly concentrically to the longitudinal axis of the respective assigned stem part (17), and in that the respective further crater-like depression (23) has a maximum crater depth ranging between 30 to 60%, preferably 50%, of the thickness of the substrate part (10).

A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane.

An absorbent article and method of making the absorbent article are disclosed. The absorbent article having a topsheet, a backsheet, and an absorbent core structure having one or more layers wherein at least one layer is a heterogeneous mass layer, wherein the topsheet and the heterogeneous mass are integrated such that they reside in the same X-Y plane.

A touch fastener product having a base sheet with a resin side surface and a male touch fastener element having a head disposed at a distal end of a resin stem and overhanging the base sheet. The head has an overall shape, as projected in a plane parallel to the base sheet, with a perimeter that defines spaced apart extremities corresponding to head sections of different engagement characteristics and disposed at different distances from a centroid of the overall shape. In one example, the head projection has a polygonal perimeter consisting of straight edges of differing lengths connected at radiused corners. In another, the perimeter comprises an unbroken series of at least three arc segments of different curvatures, with centers of the arc segments disposed at different distances from the centroid.

A method of molding resin on a flexible substrate includes forming discrete regions of resin and forcing resin of at least some of the regions into molding cavities to form a respective array of resin projections extending from a resin base of the regions. Forming the discrete regions of resin includes depositing molten resin directly onto either the substrate or a surface in which the cavities are defined. The resin is deposited as the substrate moves in a processing direction, and the resin is deposited by resin sources spaced from each other along the processing direction.

A method for assembling an assembly comprising a tape (100) of retaining elements and a substrate (200), said method comprising the following steps: a step of forming a tape of retaining elements by dispensing a molding material into a molding device (1), so as to form a tape (100) of retaining elements comprising a base (51) presenting a bottom face (511) and a top face (512), the top face (511) of the base (51) being provided with retaining elements; and a step of applying a substrate (200) against the bottom face (511) of the base (51) prior to said bottom face (512) of the base (51) solidifying in such a manner as to cause the substrate (200) to penetrate at least in part beyond a plane defined by the bottom face (511) of the base (51) of the tape (100).

Provided is a method for manufacturing a molded article obtained by double belt press molding a thermosetting prepreg, in which the thermosetting prepreg is coated with a release film during molding, and a width of the prepreg is 1 to 25 mm smaller than that of the release film. This manufacturing method suppresses burr generation and fiber twisting, and is excellent in width restriction, and thus can be suitably used for, for example, automobile members, railroad vehicle members, aerospace machine members, ship members, household equipment members, sporting goods members, light vehicle members, building and civil engineering members, and housings for OA equipment and the like.
