Abstract
A method for adjusting a radial gap (20) between two parallel rotary tools (16, 17) used for converting a flat substrate (2), the method using a converting arrangement (18) including a first and a second cylindrical rotary converting tool (16, 17), each tool provided with two laterally spaced apart conical lateral rolling rings (21, 22, 23, 24) arranged to cooperate to convert the substrate (2); a first and a second lateral bearing (26, 27), holds the first tool (16) for rotation (Rs); a third and a fourth lateral bearing (29, 31), holds the second tool (17) for rotation (Ri); clamping elements (34, 37) tighten the first to the third bearing (26, 29) and the second to the fourth bearing (27, 31). The method steps include loosening the elements for tightening (34, 37); pushing (U) the first bearing (26) away from the third bearing (29), and the second bearing (27) away from the fourth bearing (31) along a predetermined distance (e); modifying (L) a lateral position of at least one of the rings (21, 22); moving (D) the first bearing (26) radially closer to the third bearing (29), and the second bearing (27) radially closer to the fourth bearing (31), and retightening the elements for tightening (34, 37).
