METHOD AND DEVICE FOR PRODUCING PARTIALLY EMBOSSED BLANKS
A method for producing partially embossed blanks is disclosed. The method is to provide a continuous web of an embossable material, and guide it between two cylinders which emboss its surface. The embossed web is fed to a stamping device to punch blanks from the web. One of the embossing cylinders has a marking which is readable by a first sensor. The first sensor reads the position of the marking and produces a signal which triggers a printing device to produce a print mark on the web identifying the position of the embossing. The print mark is read by a second sensor which produces a signal for controlling and adjusting a feeding distance by which feed rolls supply the web to the stamping device that punches blanks from the web in register with the partial embossing of the blank. A device for conducting the method is also disclosed.
METHOD FOR PRODUCING A PAPER ROLL WITH SMOOTH PLIES AND RELATIVE ROLL
A method for producing a paper roll by conveying a first smooth ply between an upper embossing roll with first projections defining a decorative motif, and a glue distribution or cliché roll; maintaining the cliché roll side by side to the upper embossing roll, the first ply interposed between the upper embossing roll and the cliché roll and subjected to incisions and to glue deposits at the first projections on one side of the first ply facing towards the upper embossing roll and on the opposite side of the first ply facing towards the cliché roll; conveying a second ply between the upper embossing roll and a coupling or marriage roll; maintaining the marriage roll side by side to the upper embossing roll by exerting a coupling pressure to perform the final coupling between the first ply and the second ply at the glue deposits forming a multilayer paper.

Method for adjusting the radial spacing between two tools, embossing device and folder-gluer provided therewith
A radial spacing, between two rotating cylindrical embossing tools, is adjustable, in an embossing device (14) having: an armature (19, 21); a first structure (16, 24, 26, 27, 29) which is movably mounted in translation relative to the armature (19, 21), which has a first rotating cylindrical tool (16); a second structure (17, 22, 28, 31) mounted in a fixed manner on the armature (19, 21) and which is provided with a second rotating cylindrical tool (17). A method includes steps of: pushing (T) on the first structure to move it closer to the second structure by leaning on the armature (19, 21) to adjust a radial space, or pulling (P) on the first structure (16, 24, 26, 27, 29) in order to move it away from the second structure (17, 22, 28, 31) by leaning on the armature (19, 21) in order to finely adjust the radial spacing between the first and the second tools (16, 17).
