摘要:
A laminated web from which diaper closure elements may be punched is made by first applying at least two pairs longitudinally extending and transversely spaced bend-resistant strips to a first longitudinally extending nonwoven tape. Then a respective longitudinally extending strip of an elastically stretchable polymer is applied to the first nonwoven tape between each of the pairs of the bend-resistant strips with the polymer strip partially overlapping both of the bend-resistant strips of the respective pair. A second longitudinally extending nonwoven tape that covers and extends transversely to both sides of the polymer strip is applied over the bend-resistant strips and the polymer strips to form a laminate with the polymer strip between the first and second nonwoven tapes.
摘要:
A method for producing an elastic laminate material web that has elastic and non-elastic regions and has non-woven fabric on both surfaces of the web. In between the two surfaces, there are film strips of an elastic film. One surface of the web consists of a planar non-woven fabric layer and is connected with non-woven fabric that is disposed on the opposite surface of the web in areas between the film strips. Each film strip is connected with a non-woven fabric layer to form a laminate strip. The laminate strips are glued to the planar non-woven fabric layer on their film side, and the non-woven fabric that is connected with the planar non-woven fabric layer between the laminate strips is in the form of non-woven fabric strips that run parallel to the laminate strips. The non-woven fabric strips overlap the non-woven fabric layer of the laminate strips in edge regions of the laminate strips.

247,172. Klavik, M. Feb. 9, 1925, [Convention date]. Apparatus for making filaments.-The parts of the spinning apparatus are arranged so that the fi aments extruded from the spinning nozzle 2 into the coagulating bath 5 travel vertically to the godet 1 and then fall vertically into the centre of the centrifugal box 3. The edges of the godet are chamfered off in order that any filaments that may wrap round the godet are more easily removed.

A label film is formed by means of extrusion and has a layer that forms the surface, on a first side, composed of polyethylene with a proportion of at least 70 wt.-%, preferably at least 85 wt.-% high-density polyethylene, wherein the film thickness amounts to less than 75 μm. According to the invention, the 60° reflectometer value on at least the first side of the label film, determined according to DIN 67 530, is greater than 80, preferably greater than 90.

A plastic film having a thickness of less than 400 μm has a base layer at least partially of polyolefin of renewable raw material or a polyolefin mixture of renewable raw material and a first layer foamed by at least 20%.

A molded article is made by first providing a starting material comprised of a support web and a layer of expandable polymer particles on the support web. This starting material is fitted as several layers into a generally closed cavity of a mold or shaping shell so as to only partially fill the cavity. Then energy, for instance microwave radiation, is applied to the starting material in the cavity so as to expand or foam the polymer particles such that the starting material generally fills the cavity.

A molded part is made by cold-stretching a nonwoven web so as to rupture fibers or filaments thereof, laminating to a face of the cold-stretched nonwoven web a stretchable plastic film, and then inserting the laminated nonwoven web and film into a mold cavity with the film juxtaposed with an inner surface of the cavity and the cold-stretched web turned inward. This mold cavity is then filled a polymer melt to press the film against the inner mold surface while forcing the melt to penetrate the nonwoven web.
