摘要:
A thermoplastic film with a three-dimensionally structured outer surface is made by coextruding through a slit nozzle a multilayer molten plastic film having an outer layer formed of a thermoplastic polyurethane elastomer with an isocyanate additive and an inner layer. This multilayer film is compressed in a nip between a roll and a belt to emboss a three-dimensional structure into the outer layer. The roll is cooled to cool the film and set the three-dimensional structure in the outer surface of the outer layer.

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.

The invention relates to an elastic laminate. The laminate is made from a co-extruded elastic film, comprising an elastomeric support layer, at least one cover layer and at least one textile outer layer made from a non-woven. The cover layer has a low layer thickness by comparison with the support layer. The outer layer is laminated onto the cover layer. According to the invention, the cover layer is made from an elastomeric material, with essentially the same expansion properties as the material of the support layer and contains additives for modification of the surface properties.

Method for assuring that the operator of a vehicle is an authorized driver, the method including utilizing an onboard, multi-mode driver identification system to ascertain whether an operator is an authorized driver. A first driver identification procedure is performed on a present operator of the vehicle and determining whether the present operator is an authorized or unauthorized driver of the vehicle. A second driver identification procedure is performed on the present operator of the vehicle and determining whether the present operator is an authorized or unauthorized driver of the vehicle, wherein the first and second driver identification procedures are performed with a time interval therebetween, the time interval being dependent upon the nature of the work being performed by the operator. A remedial measure is exercised to avert potentially negative impact when the present operator of the vehicle is determined to be an unauthorized driver based upon at least one of the performed identification procedures.

The invention relates to the self-adhesive material of hydrogenated block copolymers or a mixture thereof, comprising polymer blocks of vinyl aromatics (A-blocks) and such made by polymerization of 1.3 dienes (B-blocks), wherein the self-adhesive material is mixed with 25 to 100 parts per weight of polyisobutylene with an average molecular weight Mw>200 000 g/mol, 3 to 40 phr (per hundred rubber=in relation to the blockcopolymeres) adhesive resin and 0.1 to 5 phr light protecting agent in relation to 100 parts per weight of the blockcopolymeres.

A monoaxially elastic laminate film is provided with a core layer made of a thermoplastic elastomer and at least one skin layer co-extruded together with the core layer. The skin layer is made of a thermoplastic plastic with a molecular lattice that becomes brittle when it solidifies, so that the plastic stretches only slightly when a stretching force is applied, and breaks without any transition when a pre-determined tear force has been exceeded. After becoming brittle, the molecular lattice is irreversibly broken up by monoaxial stretching in the stretching direction, but is maintained perpendicular to the stretching direction, and thereby reinforces the film in the crosswise direction.
