A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.

A device (1) applies adhesive to cores which are used to produce a log includes a moving means (3) configured to cause at least one core (5) to advance along a feed direction (A) and a dispensing means (7) configured for dispensing an amount of adhesive (9) on the core (5). The dispensing means (7) are moveable along an application direction (B) substantially orthogonal to the feed direction (A) and are configured to selectively dispense an amount of adhesive (9) along portions (11) of the core (5) during movement along the application direction (B).

In 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. Two cuts (C1, C2) are formed by the nozzles starting from the web edges moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts nozzle movement is stopped and after the return of the nozzles, cutting is restarted from the center toward the edges so the web W is cut by two cuts (C3, C4) forming a substantially V-shaped beginning end (V2) 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. Cross-direction travel distance (L1, L2) of each nozzle is substantially shorter than the web width.

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).

An apparatus forms stacks of interfolded sheets. First and second folding rolls receive the plurality of sheets, move the plurality of sheets through the nip, and fold the plurality of sheets into a stack of interfolded sheets downstream of the nip. A packing finger is associated with each folding roll, and the respective packing fingers move between a retracted position and an extended position relative to the corresponding folding roll with alternate movement relative to each other between the retracted position and the extended position to engage the plurality of sheets and form the stack of interfolded sheets. A fluid delivery system delivers fluid to a sheet in the plurality of sheets at or after the folding rolls.
