摘要

The assembly to bond flat sections (1,2) together at their edges, to form a hollow body, has carriers (3,4) to support each section along their butting lines. A working head (20), especially a hot air welding unit, bonds (1,2) at least at one point (21) on their butting line, and either moves along the joint between (1,2) or they are moved under the welding head. Each (3,4) has a number of swing segments (8d-8f) as retainers (5,6), with at least two free swing degrees.
