Patent ID: 6907821

Claim:
A rotary press for laying patterns of a material on a support strip, the press comprising: a rotatable working cylinder having a first axis and a first periphery; a drive for rotating the working cylinder around the first axis; a temperature control device for heating and controlling a temperature of the working cylinder; embossing plates holding the patterns of the material to be laid on the support strip, the embossing plates being held on the first periphery of the working cylinder; a rotatable anvil cylinder having a second axis and a second periphery, the anvil cylinder being positioned with respect to the working cylinder such that the first periphery of the working cylinder is spaced apart from and in opposition to the second periphery of the anvil cylinder; a shalt through the anvil cylinder along the second axis; bearings between the anvil cylinder and the shaft for supporting the anvil cylinder for rotation on the shaft; a prestress application assembly operable to exert a defined prestress between the working cylinder and the anvil cylinder; and a space adjustment device connected to at least one of the working and anvil cylinders to adjust the space between the working cylinder and the anvil cylinder, the space adjustment device being independent from the prestress application assembly, wherein the space adjustment device comprises: at least one first cylindrical part coupled to the working cylinder; at least one second cylindrical part mounted on the shaft through the anvil cylinder, and in contact with the first cylindrical part, the second cylindrical part being independently movable with respect to the anvil cylinder, the shaft through the anvil cylinder having at least one pivot portion respectively assigned to the second cylindrical part on which the second cylindrical part is defined, and the pivot portion is eccentric with respect to the second axis of the anvil cylinder; and an angle adjustment device for selectively adjusting an angular position of the eccentric pivot portion of the shaft through the anvil cylinder for adjusting the space between the first and second peripheries of the working cylinder and the anvil cylinder.
