Abstract: A support and stabilization unit (200, 300, 400, 500) for a web (20) advancing in its longitudinal direction over the unit from upstream to downstream; the unit includes in series at least one rotating support roller (31, 32) that is able to come into contact with an underside of the web (20), and at least one device (121, 122, 122′) for tensioning the web (20). The tensioning device (121, 122, 122′) includes a guiding face (121a, 122a) oriented toward the underside of the web (20), an internal cavity connected to the outside of the device via an outlet opening (121d) which is oriented toward the guiding face (121a, 122a), and an air inlet inside the internal cavity (121b), so as to produce, on the web (20), a force (F2) oriented toward the guiding face (121a, 122a).

Abstract: An arrangement for cutting off and ejecting waste from a planar support (3), includes a first rotating cylindrical tool for ejecting waste (16), the surface of which has at least one radial, waste-retaining needle, a second rotating cylindrical tool (17), first and second side bearings (26, 27), holding the first tool (16) for rotation, third and fourth side bearings (29, 31), holding the second tool (17) for rotation, and at least one ejector (39); the two tools (16, 17) and the ejector (39) cooperating to eject the waste from the support (3). The ejector (39) is fixed transversely to a lower portion of the first and second bearings (26, 27) respectively.

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).
