Abstract: A packaging machine including an insertion station for inserting the rolls in wrapping sheets; a feed path of the rolls; a conveyor for feeding the rolls along the feed path; and a folding station adapted to be equipped alternatively with different types of folding members, as a function of the type of pack to produce.

Abstract: A device for launching products into a feeding path, including a launcher; a detection sensor to detect the passage of products launched by the launcher; a launcher central control unit; conveyors to move forward the products in the feeding path, associated with a drive member; and at least one movement sensor to detect the position of the products moved by the conveyors. The central control unit is programmed to control the start position taken by each group of products, downstream of the detection sensor, and to impose on each group of products a forward movement according to the length of the group of products and to an adjustment factor determined by the error, if any, between the detected start position and a desired start position.

Abstract: The machine includes a spindle; a winding unit, cooperating with the spindle to wind one or more strips of web material about the spindle and form a tubular element; and a cutting unit with at least one discoidal cutting tool to divide the tubular element into tubes of a length which can be predetermined. At least one pressure element is associated with the cutting tool to compress the tubular element between the spindle and the pressure element adjacent to the cut performed by the cutting tool.

Abstract: The device for joining at least two plies of paper, in particular tissue paper, including a ply-bonding unit and moistening means to moisten at least one of the two plies before joining.

Abstract: The device for joining at least two plies of paper, in particular tissue paper, including a ply-bonding unit and moistening means to moisten at least one of the two plies before joining.

Abstract: The device for joining at least two plies of paper (V1, V2), in particular tissue paper, comprises a ply-bonding unit (9) and moistening means (11) to moisten at least one of said two plies before joining.

Abstract: An embossing roller for processing a web material comprises a central axle (53) and a removable and interchangeable outer sleeve (51); the interchangeable sleeve has an essentially cylindrical outer surface provided with protuberances and/or cavities. The axle has radially expandable elements (61) to clamp the sleeve.

Abstract: The interchangeable sleeve comprises: a substantially cylindrical outer surface (105A); a layer of hardened resin (R); a substantially conical inner surface for connection to a conical central core of the roller. The inner surface is formed at least partially of at least one inner component (102) having greater rigidity than said hardened resin. The inner component is constrained to the sleeve by means of said hardened resin.

Abstract: A method of making wet rolls includes providing a web of material, applying a wetting solution to the web to produce a wet web, and winding the wet web into a roll. The wetting solution may include an inorganic salt and at least one preservative. The wetting solution may be distributed evenly throughout the wet roll.

Abstract: The device comprises: a first embossing unit (3) with a first embossing roller (5) equipped with a first series of protuberances (5P); a second embossing unit (13) with a second embossing roller (15) equipped with a second series of protuberances (15P) of greater height and lesser density with respect to the protuberances of said first series, said protuberances defining decorative motifs; a glue dispenser (19) associated with said second embossing roller, to apply a glue to a first ply (V1) embossed by said first and said second embossing unit at the protuberances of said second embossing roller; a laminating member (21) associated with said second embossing roller to apply a second ply (V2) to the first ply. At least a printing unit (9), which applies an ink to said first ply (V1) at the protuberances of the first embossing roller, is associated with the first embossing roller (5).

Abstract: A method of making wet rolls includes providing a web of material, applying a wetting solution to the web to produce a wet web, and winding the wet web into a roll. The wetting solution may be applied at an add-on greater than 25%, and the web may travel at a speed of at least 60 meters per minute.
