A method for securing a web end of a paper web on a first drum during a change of drum, the method includes passing the web end through a nip between a Pope roller and the second drum and applying adhesive to an area of the web end on a downward-rotating area of the Pope roller after the web end is passed through the nip.

A nonadhesive phase-change material application apparatus for bonding the tail of a convolutely wound log to the body is provided. The nonadhesive phase-change material application apparatus has at least one nonadhesive phase-change material applicator that defines a cavity conveying a volume of nonadhesive phase-change material from a reservoir to an application site.

Rewinding machine for producing paper logs by winding a paper web, include: an element for feeding a paper web along a predetermined path at a predetermined feeding speed; web pre-cutting elements; web winding elements; web sizing elements, with a pad adapted to cyclically apply glue by contact on the web, the pad being mounted on a pad-holder device connected with a corresponding actuator. The pad is mounted on the pad-holder device by an elastic support which deforms elastically, such that the pad moves elastically towards the pad-holder, when it is subjected to a pressure and moves automatically in the opposite direction returning to its previous position when the pad is no longer subjected to a pressure.

A feeding path (P) is provided for rolls (R, R1) to be closed and a closing station placed along that path. Two rollers (15, 17) form a cradle (19) for receiving the rolls (R, R1). A closing member (21) is provided to close a tail end (L). A rotating assembly (23) rotates around an axis (A-A) transverse to the feeding path and has groups (27A, 27B, 27C) of arms (28A; 28B, 28C) arranged with respect to one another angularly displaced around the rotation axis of the rotating assembly (23). Each arm has a front part (29) to eject a roll (R, R1) from the cradle (19) and a back part (31) to prevent a subsequent roll entering the closing station until the ejection of a roll from the cradle (19). Rotation of assembly (23) causes closed roll ejection and allows a subsequent roll (R1) to enter and be closed.

A method for manufacturing a marked toilet paper roll by winding a sheet of wide toilet paper a predetermined length about a winding shaft to form a log roll and by cutting the log roll at a predetermined width into a plurality of toilet paper rolls, the method including marking stamps at intervals, each interval of the predetermined width, on an end portion of a winding end of the log roll before the log roll is cut into the toilet paper rolls.

The machine includes a first glue-applying device for closing the tail end; and a second mechanical-closing device for mechanically anchoring the tail end of the roll to a portion of an outer turn of the web material wound on the roll.
