METHOD FOR ADJUSTING THE RADIAL GAP BETWEEN TWO TOOLS, CONVERTING ARRANGEMENT FOR A SUBSTRATE, CASSETTE, UNIT AND A MACHINE PROVIDED THEREWITH
First Claim
1. A method for adjusting a radial gap between two tools configured for converting a flat substrate, in a conversion arrangement for the substrate, said method comprising:
- a first and a second cylindrical rotary converting tool, each tool supporting thereon respectively two spaced apart, conical shape, laterally movable, rolling rings and the two rings on each tool are arranged to and cooperate with respective ones of the two rings on the other tool to adjust the radial gap to convert the substrate;
a first and a second bearing which are laterally spaced apart, each holding the first tool for rotation;
a third and a fourth, bearing which are laterally spaced apart each holding the second tool for rotation;
elements for tightening the first bearing toward and to the third bearing and the second bearing toward and to the fourth bearing;
the method comprising steps of;
loosening the elements for being tightened and which are located to control movement apart of the opposing bearings;
pushing the first bearing away from the third bearing, and pushing the second bearing away from the fourth bearing along a predetermined distance;
then modifying a lateral position of at least one of the rings on one of the tools;
moving the first bearing closer to the third bearing, and moving the second bearing closer to the fourth bearing to set the gap; and
retightening the elements for tightening.

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).

3. A converting arrangement for converting a flat substrate, the arrangement comprising:
-
a first and a second cylindrical, rotary converting tool, wherein the two tools are so arranged and so configured as to cooperate to convert the substrate; a first and a second lateral bearing, which are laterally spaced apart for holding the first tool for rotation; a third and a fourth lateral bearing, which are laterally spaced apart for holding the second tool for rotation; and translation means configured to move apart along a predetermined distance (e), and conversely configured to move closer, for the first bearing from/to the third bearing, and the second bearing from/to the fourth bearing, between two positions, wherein one position is moved closer and in which the two tools cooperate, and another position is moved apart in which the two tools are there capable of being modified to adjust a radial gap between the two tools. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
