A dunnage production system for producing coiled strips of dunnage includes a supply of strip-like dunnage, a coiler adjacent the supply and rotatable about a coiling axis for coiling a strip of the strip-like dunnage into a coil having a coiled configuration, and a tube aligned with the coiling axis. The tube has an internal diameter sized to receive the coil from the coiler in a discharge direction parallel to the coiling axis. The tube is capable of holding at least one coil in its coiled configuration until it is removed from the tube.

In a turn-up method for a reel-up for reeling of fiber webs, a web travelling in direction (S) is cut by two water jet nozzles moving in a transverse direction in relation to the web travelling direction (S). Two cuts (C1, C2) are formed by two water jet nozzles starting from the edges of the web (W) and moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts the movement of the water jet nozzles is stopped and after the return movement of the water jet nozzles, cutting is started again from the center toward the edges so that the web W is cut by two cuts (C3, C4) and a substantially V-shaped beginning end (V2) to the web W is formed and between the cuts (C1, C2) for the tail end (V1) and the cuts (C3, C4) for the beginning end (V2) there is formed one web reject part (R) with two substantially V-shaped cuts. A turn-up device for a reel-up for reeling of fiber webs has two water jet nozzles, in which the cutting by the water jet nozzles (10,12) may be stopped between cutting of a tail end (V1) and cutting of a beginning end (V2) for a selected time for forming only, wherein there is one reject part (R) in the turn-up and the cross-direction travel distance (L1, L2) of each nozzle is substantially shorter than the width (L) of the web (W).

A gluing device of an end edge of a log including an introduction assembly into the gluing device of a log, a handling assembly for a log associated to detection device of the end edge and including a pair of rolls for advancement and holding in rotation of the log, a glue dispensing assembly and a transfer assembly of the log including a transfer plane positioned downstream of the lower handling roller. The glue dispensing assembly is placed in series between the lower handling roll and the transfer plane and includes a transverse tank for the glue, housing cyclically movable glue transfer members. The transverse tank is provided with an upper cover provided with a plurality of openings provided in succession side by side at a set distance along a transverse row. The movable glue transfer members include a plurality of tips provided in succession along a transverse row, alternatively projecting through the relevant openings and retracted within the transverse tank because of the cyclical movement.
