Abstract: The rewinding machine includes a first winding cradle, formed between a first winding roller, a second winding roller and a third winding roller and a second winding cradle formed between the first winding roller, the second winding roller and a fourth winding roller. The first winding roller and the second winding roller define a nip through which nip the winding cores, around which the web material is found, pass and the web material is fed towards a roll being formed in the second winding cradle. A severing member is furthermore provided, acting on the web material between a winding core and the nip, to sever the web material thus generating a tail edge of a completed roll and a leading edge of a new roll to be wound.

Abstract: The machine includes a forming spindle around which one or more strips of web material are wound; a winding unit to wind the strips of web material around the forming spindle and form therewith a tubular article; and a cutting unit to cut the tubular article into single tubes. The machine also includes at least one magnetic device to support the forming spindle to reduce the flexural deformations thereof.
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: A method for obtaining an incision in an embossing roller using a hob to provide protuberances that are rounded on top and which improve the quality of the embossed material and reduce the wear of the mechanical components of the embossing units. The shape of the protuberances is obtained by machining the cylindrical surface of the roller placed between the tailstocks of the lathe using a hob that has teeth, the profile thereof being complementary to the cross-section of the protuberances. A portion of the hob with the teeth generates the grooves that define the side faces of the protuberances. The grooves between the teeth of the hob have a profile that is curvilinear in a cross-sectional view. With a double pass at two different inclinations of the surface of the roller, the protuberances of FIGS. 5 and 6 are generated.
Abstract: The gluing device includes a log feeding path that extends at least partially between a flexible conveying member and a feeding surface; and a log inserter that sequentially introduces logs between the flexible conveying member and the feeding surface. The inserter includes a flexible input member, provided with pushing elements for pushing single logs between the flexible conveying member and the feeding surface.
Abstract: A gluing device including a guide roller to guide the tail of the log; on the guide roller, retaining elements to engage and retain the tail on the guide roller; a gluing member, to apply a glue to the tail retained on the guide roller. There are also provided embossing members, arranged and controlled to emboss a portion of the tail of the log. The gluing member applies the glue to embossing protrusions formed by the embossing members.
Abstract: The embossing unit includes in combination: a first support for a first embossing roller and a second support for a first pressure roller, cooperating with the first embossing roller. The second support presents two seats to receive and support the first pressure roller in two different positions with respect to this support. The embossing unit also includes a third support for a second embossing roller. The third support can take at least two different operating positions. A fourth support is provided to support a second pressure roller suitable to cooperate with the second embossing roller and suitable to take at least an operating position and an idle position. Finally, there is provided a fifth support with a double seat to receive and support in two different positions alternatively a marrying roll or the second pressure roller.
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: A method is described for obtaining a coreless roll of web material with a first portion of web material forming an inner nucleus of the roll and a second portion of web material wound around the outside of the inner nucleus. The two portions can be separated from one another and, for that purpose, an interface or discontinuity is created in at least one turn of the web material forming the roll between the inner nucleus and the second portion of web material. This facilitates the extraction of the inner nucleus from the outer portion of the roll.
Abstract: The machine includes a first winding roller and a concave plate extending around the first winding roller. The first winding roller and the concave plate define a feed channel of the web material. Upstream of the concave plate there is arranged a moving member including a pinching surface cooperating with the first winding roller to pinch the web material against the first winding roller. The moving member is arranged and controlled to pinch the web material against the surface of the first winding roller and decelerate the web material between the moving member and the surface of the first winding roller, causing a leading edge to wind around itself to form a winding nucleus of a log.
