A rotary-tool sleeve extractor for a unit for converting a flat substrate that includes a base (23) intended to be fixed to the conversion unit (7) and an extraction head (24) that: a) is movable with respect to the base (23) between a withdrawn position and a deployed position and, b) has a gripper (25) that can engage with a sleeve (13) of a rotary tool (10, 11).

This disclosure relates to an apparatus for manufacturing a tissue paper product, such as toilet paper or household towel. The apparatus comprises an embossing unit comprising a first counter roll, a first heatable embossing roll, a second counter roll, and a second heatable embossing roll, and a marrying roll. The apparatus is configured to emboss a first ply between the first heatable embossing roll and the first counter roll, to emboss a second ply between the second heatable embossing roll and the second counter roll, and to ply-bond the first ply and the second ply between the first heatable embossing roll and the marrying roll.

An embossing and lamination assembly including two pairs of steel/rubber rolls, between which respectively a first paper ply and a second paper ply are returned, wherein an upper steel embossing roll is coupled with an upper embossing rubber counter-roll and a lower steel embossing roll is coupled with a lower rubber embossing counter-roll, and also including a glue delivery assembly, in contact on a side of the upper steel embossing roll, and a coupling roll, in contact with the opposite side of the upper steel embossing roll, wherein the surface of the upper steel embossing roll and/or of the lower steel embossing roll is heated with a heating device directly associated therewith. A relative embossing and lamination method is also disclosed.

An embossing group includes: a first embossing roller and at least one embossing unit associated with the first roller. The embossing unit includes a second embossing roller, a third embossing roller, and a sleeve surrounding the second roller and the third roller by coupling them. The sleeve faces the first roller and is configured to contact the first roller. The embossing unit and the first roller are configured to emboss at least one paper sheet wound between the first roller and the embossing unit.

A relative embossing and lamination method is also disclosed.

A seamless, embossed or cast substrate is formed using a seamless sleeve having a seamless surface relief formed thereon and configured to slide over an cylindrical base in an embossing or casting assembly. The substrate is a flat web, foil, or film of, for example, paper, polyester, polypropylene, metal or other elongated flat material. The surface relief can be applied through interfering ablation, non-interfering ablation, ink jet printing, or other techniques wherein a seamless surface relief is formed onto the seamless sleeve. A method of making a seamless, embossed or cast substrate includes expanding a diameter of a seamless sleeve having a seamless surface relief formed thereon, sliding the expanded seamless sleeve onto a cylindrical base, allowing the diameter of the seamless sleeve to contract around the cylindrical base, and conveying a substrate through the embossing or casting assembly and embossing or casting the seamless surface relief into the substrate.

The disclosure relates to a system for processing a ready-to-use web of a laminated packaging material including: a first rotatable roller and a second rotatable roller, wherein the web of laminated packaging material is wound from the first roller to the second roller a sensor for detecting a marking on the packaging material, said marking located at a predetermined position on said packaging material; at least one module arranged between the first rotatable roller and the second rotatable roller and configured to process the laminated packaging material; and a control unit connected to the sensor and the module. The control unit is configured to control the module based on the detected marking and/or information stored in the control unit. The disclosure also relates to a method for processing a ready-to-use web of a laminated packaging material, and a laminated packaging material.

In some embodiments, a method for manufacturing a packaging material includes forwarding a web of said packaging material through a nip provided between an anvil roller and an imprint roller which are arranged against each other, said imprint roller having a surface area including an imprinting area and a non-imprinting area, said imprinting area comprising protrusions forming an imprinting pattern. The method can further include imprinting the imprinting pattern into an outermost layer of said packaging material with said imprinting pattern as said web passes through the nip to form a visual or tactile pattern on the packaging material corresponding to said imprinting pattern. The method can further include adjusting the position of said web when said non-imprinting area of said surface area faces said packaging material The disclosure also relates to an apparatus for manufacturing a packaging material and a packaging material.

An embossing group includes: a first embossing roller and at least one embossing unit associated with the first roller. The embossing unit includes a second embossing roller, a third embossing roller, and a sleeve surrounding the second roller and the third roller by coupling them. The sleeve faces the first roller and is configured to contact the first roller. The embossing unit and the first roller are configured to emboss at least one paper sheet wound between the first roller and the embossing unit.
