摘要： A method for producing a plastic composite panel which is provided as a layer structure. The method includes providing a film layer structure comprising an adhesive layer which is arranged between two transparent plastic films. The film layer structure is pre-molded to assume an approximately final shape and is arranged in a molding tool so that a first main surface of the film layer structure is towards the molding surface of the molding tool and so that a cavity is formed between the second main surface of the film layer structure and a surface of the molding tool. The film layer structure is then back-molded in a thermal molding method step while introducing a thermoplastic material into the cavity to provide the layer structure. A pre-molding and back-molding step, a rigidification of the thermoplastic layer, and a demolding of the layer structure is further performed.

摘要： The present disclosure relates to a control device with at least one touch-sensitive input surface that can be activated for haptic feedback with an electromagnetic actuator, where the actuator comprises an actuator coil and an armature that is activated by energizing the actuator coil. The control device is divided into at least two control assemblies at least one of which has a touch-sensitive input surface and an armature connected therewith. These at least two control assemblies are installed at a minimum spacing from each other on a common circuit board, which in turn is connected with a common carrier element, whereby the armatures protrude through the circuit board with play. On each carrier element, an actuator coil at a spacing x from the armature of the respective control assembly is installed. The present disclosure also refers to a process for manufacturing the control device.
