Abstract:
The invention relates to a method and a device for laminating sheet-shaped workpieces (2) with a flexible, fixable (20) coating material (6). The surfaces (4) of the workpieces have contours which are oriented differently in relation to a lengthways and widthways direction of the workpiece. The inventive method comprises the following steps: the continuous movement of the workpieces (2) on a plane support surface (E) in a predetermined running direction (D); conveying (14, 22) and laying (22) the coating material (6) on the surface (4) of the workpiece to be coated, said workpiece moving continuously; and pressing (16) the coating material (6) onto the surface to be coated by means of at least one pressing element (22 24, 26) which moves during the pressing process. Said pressing element has at least one elastic pressing body (28) which is allocated to the coating material (6) and the surface (4) to be coated. The coating material (6) is therefore continuously fitted to, pressed on and fixed to the surface (4) to be coated and its differently orientated contours.
Abstract:
Es werden Vorrichtungen und Verfahren zur Herstellung von Kern-Verbundwerkstoffen (Sandwichstrukturen) aus mindestens einer ersten und mindestens einer zweiten Deckschicht (1, 2), zwischen denen sich eine Kernschicht (Mittelschicht) (30) mit insbesondere kurzgeschnittenen Fasern (9) befindet, beschrieben, mit denen eine kontinuierliche und im wesentlichen unterbrechungsfreie Herstellung möglich ist, die zu relativ kostengünstigen Verbundwerkstoffen führt. Mit verschiedenen Ausführungsformen können ausserdem einzelne Herstellungsparameter gezielt verändert werden, so dass in relativ einfacher Weise Verbundwerkstoffe mit gewünschten physikalischen Eigenschaften z. B. im Hinblick auf ihre Festigkeit, Steifigkeit, Flexibilität, ihr mechanisches und akustisches Absorptionsvermögen, ihre Verarbeitbarkeit usw. sowie für neue Anwendungen hergestellt werden können.
Abstract:
A method of fabricating an elastomeric structure, comprising: forming a first elastomeric layer on top of a first micromachined mold, the first micromachined mold having a first raised protrusion which forms a first recess extending along a bottom surface of the first elastomeric layer; forming a second elastomeric layer on top of a second micromachined mold, the second micromachined mold having a second raised protrusion which forms a second recess extending along a bottom surface of the second elastomeric layer; bonding the bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer such that a control channel forms in the second recess between the first and second elastomeric layers; and positioning the first elastomeric layer on top of a planar substrate such that a flow channel forms in the first recess between the first elastomeric layer and the planar substrate.
