Abstract (en)
[origin: EP1479458A2] The tube and stock producing process involves producing a tube (11) or stock with varying wall thickness along the length. Endless strip material is flexibly rolled with variably reduced final thickness in the longitudinal direction of the strip. The strip material is deformed into an endless tube or stock article. This is then cut into sections (12, 13, 14, 16).
