SKIN FOR DRESSING BACKLIT VEHICLE INTERIOR PARTS, METHOD AND INSTALLATION FOR MANUFACTURING THEREOF
Skin for dressing backlit vehicle interior parts comprising a perforated opaque decorative layer and a light transmitting material filling the holes wherein the light transmitting material is a reactive hotmelt adhesive which forms a base layer extended over the back side of the opaque decorative layer and comprising a central portion and a transition portion surrounding the central portion and several projections protruding from the central portion of the base layer and completely filling the through holes. Method and an installation for manufacturing said skin for dressing backlit vehicle interior parts.
Continuous Encapsulated Linear Lighting Produced in Segments
A method for making continuous encapsulated linear lighting is disclosed. In this method, a PCB is placed within a channel, and the channel is dammed by one or more stoppers. The dammed segment is filled and then caused or allowed to cure. The stoppers are then removed from their initial positions and moved along the channel. If one runs out of channel before the desired length of linear lighting is achieved, a second piece of channel is abutted to the previous segment of channel, the PCB is laid into it, and a segment is dammed, filled, and cured. The process continues iteratively until the desired length is achieved or more channel is required. The PCB may initially be cut to the full desired length and applied to the channel piecewise as needed.
PREHEATING ARRANGEMENT FOR A WELDING DEVICE, A RESPECTIVE WELDING DEVICE AS WELL AS A PREHEATING METHOD AND A WELDING METHOD
A preheating arrangement includes a preheating device defining a first plane by a first centerline along a first axis and a second centerline along a second axis perpendicular to the first axis. A first preheating structure is asymmetric with respect to the first and/or the second centerline. A second preheating structure is oriented like the first preheating structure such that, when viewed along a third axis perpendicular to the first plane, the preheating structures are arranged one above the other. A first actuator rotates the preheating device between first and second positions and the preheating structures in the first position have a first orientation and in the second position a second orientation rotated around the axis of asymmetry by 180° or in which they are rotated by an angle α in the range of 0°<α<360°, or 90°≤α≤270° or α=180° around the third axis compared to the first orientation.
Automotive lighting and/or signaling device and assembly method thereof
A lighting and signaling device for automotive vehicles, comprising a container body delimiting a containment housing closed by a lenticular body, which accommodates at least one first light source and is closed by a lenticular body, a first light guide configured to receive as input at least partially the light beam produced by the first light source, transmits the light beam by total internal reflection along a first prevailing propagation direction and sends it as output from the lenticular body. A fixing and/or screen element, opaque to the light beam is associated with the first light guide at a first interface wall, and is fixed either directly or indirectly onto the container body to mechanically block the first light guide onto the container body. The first light guide is mechanically fixed to the fixing and/or screen element by at least one first welding portion which projects from the first interface wall.
