Changeover of upper drive/pressure roller
• Different overlap joints can be produced with the Leister TWINNY T for various applications, e.g. in tunnel cons-
truction or civil engineering. These differ in width of the welded seam and in width of the test channel. Wel-
ding seams without test channel can also be produced. In order to achieve these different welding seams, the
appropriate drive/pressure rollers have to be installed. These drive/pressure rollers are manufactured either in
aluminium or stainless steel depending on customers' requests.
