Abstract

Method and device for connecting two webs (), reinforced with unidirectionally oriented continuous fibres, by ultrasonic welding, wherein the fibres are embedded in a matrix of polycarbonate and the webs have abutting edges that are substantially square and substantially flat, characterized by the following steps:—arranging the webs abutting one another in the region of the abutting edges in a welding device between a sonotrode () and an anvil (),—welding the webs by means of ultrasound, wherein the sonotrode and the anvil exert pressure on the webs to be welded in the melting region between the webs and perpendicularly to the abutting edges of the webs,—removing the welded-together webs () from the welding device.
