A laminate includes a transfer layer and a polycarbonate layer. The transfer layer has a plurality of layers including a transparent reflection layer. The transparent reflection layer is a visible light refractive index of greater than or equal to 2.0. In a plan view of a plane in which the transfer layer extends, the transparent reflection layer is located in a part of the transfer layer. At least a part of the transparent reflection layer is located inside an outline of the transfer layer. A portion of the transfer layer that is nil of the transparent reflection layer is a visible light refractive index of between 1.4 and 1.8 inclusive. The polycarbonate layer encloses the transfer layer. Across section in a thickness direction of the laminate includes a first cross section that is nil of the transfer layer, a second cross section including the portion of the transfer layer that is nil of the transparent reflection layer, and a third cross section including a portion of the transfer layer that includes the transparent reflection layer.

A nonwoven web having a first web layer and a second web layer are disclosed herein. Methods of making such webs and absorbent articles including those webs are also disclosed. The first web layer has a core/sheath first composite fiber having a fiber fineness no greater than about 2.5 denier. The second web layer has a core/sheath second composite fiber having a fiber fineness no greater than about 2.5 denier and a homopolymer fiber having a fiber fineness of greater than about 3 denier. The homopolymer fiber is less than about 30% by weight of the second web layer.

The invention relates to a separation device (400) for separating portions (04) of a material web (02), the separation device (400) having at least one front clamping device (406), with at least one front clamping point (401), and at least one rear clamping device (404), with at least one rear clamping point (402), and at least one first stretching element (403). The separation device (400) can be switched between at least one traversing mode and at least one separation mode by the movement of at least the at least one first stretching element (403) between at least one first traversing position and at least one first separation position. A transport line is the shortest connection between the at least one front clamping point (401) and the at least one rear clamping point (402), said connection lying completely on a vertical reference plane and traversing or running at a tangent to any component of the separation device (400) on the respective same side as a transport path provided for the material web (02) and/or the portions (04), wherein the transport line in the at least one separation mode is 2 mm longer than in the at least one traversing mode and has the smallest radius of curvature in the at least one separation mode of at least 0.05 mm. A first reference plane and a second reference plane are mutually spaced apart in an axial direction (A) and a first transport line lying on the first reference plane and a second transport line lying on the second reference plane have different lengths when the first stretching element (403) is located in the at least one first separation position.

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer zumindest zweilagigen Platte durch thermisches Verschweißen von mindestens einer dünneren thermoplastischen Schaumstoffplatte (TS) und mindestens einer dünneren Platte (IM) als Ausgangsplatten. Die mindestens eine dünnere thermoplastische Schaumstoffplatte (TS) weist eine größere Dicke auf als die mindestens eine dünnere Platte (IM) und die mindestens eine dünnere Platte (IM) ist aus einem anorganischen Isolationsmaterial hergestellt. Weiterhin betrifft die vorliegende Erfindung die zumindest zweilagige Platte als solche sowie deren Verwendung als Brandschutz für die Außenfassade eines Bauwerks. Darüber hinaus betrifft sie auch die Außenwand (AW), auf die die zumindest zweilagige Platte aufgebracht ist.

Described embodiments relate to a method of manufacturing a sound absorption material. The method comprises: forming a low density fibrous web to act as a porous bulk absorber, the fibrous web containing a proportion of bi-component fibers, each bi-component fiber having a core material and a sheath material around the core material, the sheath material having a lower melting point than the core material; applying a thin facing layer to the low density fibrous web, wherein the facing layer is adhesively compatible with the sheath material; heating the fibrous web to a temperature sufficient to soften the sheath material of at least some of the bi-component fibers; and pressing the facing layer and fibrous web together under low pressure such that at least part of the facing layer contacts the softened sheath material of at least some of the bi-component fibers to form an adhesive bond between the facing layer and the fibrous web.

Process and machine for manufacturing printed circuit boards wherein a press packet comprised of at least two press plates of metal material between which is arranged a printed circuit board composition formed by one or more metal sheets, by one or more layers of insulating material impregnated with polymerizable resins and/or by one or more printed circuit boards with an engraved image of a circuit, are arranged between the press plates of a press and is pressed, subjecting said press packet to the action of a variable induction magnetic field which generates induced currents in each metal plate and sheet of the press packet, causing the heating of said plates and sheets, in turn causing the heating by thermal conduction of the layers of insulating material, melting and liquefying the resins in said layers of insulating material and adhering the insulating material to the metal sheets, so that, on raising the temperature even more, the polymerizable resins in the layers of insulating material are then polymerized, resulting, after the cooling of the press packet, in one or more rigid boards suitable for making printed electronic circuits. The machine to carry out the above process comprises a variable induction magnetic field generating device adapted to generate induced currents in the press packet's metal plates and sheets, causing them to heat, and means of controlling the operation of the magnetic field generating device and controlling the temperature and pressure to which the press packet is subjected.
