METHOD AND DEVICE FOR FIXING PIECES OF MATERIAL ON A CONTINUOUS WEB
摘要
<p>The invention relates to a device and a method for producing a material laminate (1) by fixing pieces of material (2) at a given distance from one another on a first continuously advanced material web (4). The invention is characterized in that the pieces of material (2) are cut from a second continuous material web (7) in a first station (3) and are conveyed via a transport device (10) to the first web (4), to which the piece of material (2) is attached by means of ultrasonic welding over a limited attachment area (5) on the pieces of material (2), and the pieces of material (2) are subsequently fixed on the material web (4) by ultrasonic welding in a second station (6). The second station comprises an ultrasonic horn (18) at a fixed distance from a stay (19) designed as a rotating drum with a patterned outer surface.</p>
