Abstract
The invention relates to a welding device (1) for producing tubular bodies by the edge-side welding of two substrate edges (2, 3), in particular two laminate edges, said welding device having a continuous, circulating first contact belt (5) for coming into contact with the substrate (4), and an energy source (12, 13) for providing welding energy. According to the invention, the first contact belt (5) has a seamless polyimide contact surface (35) for coming into contact with the substrate (4).

Welding device (1) for producing tubular bodies by edge-side welding of two substrate edges (2, 3),
- having an endless, circulating, first contact belt (5) for coming into contact with the substrate (4),
- having an energy source (12, 13) for providing welding energy,
- and having means for conveying the substrate (4) along the energy source (12, 13) while the substrate edges (2, 3) are welded,
- characterized in that
- the first contact belt (5) has a seamless polyimide contact surface (35) for coming into contact with the substrate (4).
Method for producing tubular bodies in which a substrate (4) having two substrate edges (2, 3) is welded on the edge side by a welding device (1), wherein a first endless contact belt (5) is brought into contact with the substrate and wherein the substrate (4) welded by means of an energy source (12, 13) past which the substrate is conveyed during welding, characterized in that the first contact belt (5) comes into contact with the substrate (4), with a seamless polyimide contact surface (35, 36).
