When the sub-frame comprising the adhesive unit is released and spaced from main frame structure, the roll may be removed from and installed into the main frame structure.
An embosser/laminator machine (LEM) has an adhesive unit (2) releasably connectable with a main frame structure (3) of the machine, and a roll extractor (10) configured to move a roll (7) between the main frame structure and an exchange position between the main frame structure and the adhesive unit when the adhesive unit is spaced from the main frame structure during removal and installation of the roll. The sub-frame comprising the adhesive unit (2) may be formed with a bearing cap (9) that cooperates with the main frame structure such that when the adhesive unit is connected with the main frame structure, the roll is operatively secured to the machine between main frame structure and the sub-frame of the adhesive unit for normal operation of the machine.

The invention relates to a device and method for cleaning the surface of a printing roll, such as an anilox roll. The device includes a laser-equipped assembly adapted to project a laser beam on the surface of the printing roll. The laser-equipped assembly uses a reflector and a lens to guide the laser beam along a predetermined path on the surface of the printing roil. In some embodiments, an autofocus system may be included to move the lens so that the desired focal point for the laser beam on the printing roll surface is achieved.

A method of forming a roll of convolutely wound web material. The method includes applying adhesive to an elongated mandrel, winding web material around the mandrel to form a roll of convolutely wound web material, rotating the mandrel relative to the roll to smear the adhesive, and removing the mandrel from the roll. The smearing can be in a circumferential direction. The adhesive can be applied longitudinally along the mandrel. The adhesive preferably has a viscosity within the range of 3000 to 18,000 cps. Preferably, the method includes pulling the mandrel longitudinally before the step of removing the mandrel from the roll. The pulling can reduce the mandrel diameter and/or can increase its length. The rotating can be conducted before the pulling, during the pulling or during the winding. The rotating can be conducted before or during the removing. The web material can be bathroom tissue or kitchen towel.
A method of forming a roll of convolutely wound web material. The method includes winding web material around an elongated mandrel to form a roll of convolutely wound web material. The mandrel is substantially axially elastic and formed of material having a tensile yield strength divided by elastic modulus greater than 2.0%, and more preferably 2.5%. The mandrel is preferably radially complaint. The method further includes removing the mandrel from the roll. A further method includes winding web material around an elongated mandrel to form a roll of convolutely wound web material, the mandrel being comprised of material having a tensile yield strength divided by elastic modulus greater than 2.0%, and then longitudinally elongating the mandrel.
The mandrel is formed from flexible and elastic material, and after the roll is wound, the mandrel is pulled longitudinally and withdrawn from the roll of paper to form a coreless roll.
