Changeover of upper drive / pressure roller
For various applications, for example tunnel construction or civil engineering at or below ground level, various
overlap-welded seams can be manufactured with the LEISTER Comet. These differ in the width of the welded
seam and the width of the test channel. Also welded seams without a test channel can be manufactured. In
order to implement these different overlapped seams, the appropriate drive/pressure rollers must be fixed.
These drive/pressure rollers can be produced in aluminium or stainless steel according to the customer's
requirements.
