摘要:
The invention relates to a device (21) for welding a first thermoplastic membrane (12) to a second thermoplastic membrane (13), in which at least the first thermoplastic membrane (12) or the second thermoplastic membrane (13) is absorbent. The invention is characterised in that the welding device (21) comprises at least one die (1) including a plurality of laser diodes (2) for emitting a laser beam (F) forming direct, simultaneous and uniform illumination on the illumination surface (23) of the first thermoplastic membrane (12).
摘要:
Method for manufacturing a cell-like honeycomb structure, formed from a plurality of thermoplastic sheets (101) attached to each other, wherein contoured areas (2a and 3a) are provided in each sheet, and each free sheet (101b) is attached to an adjacent sheet (101a) of an intermediate block (21) formed by the different sheets previously attached therebetween, welding at least some of the flat areas (3a and 2b) contacting this free sheet and this adjacent sheet with a laser source along a continuous line (L) parallel to the contour axis.
