A winding station and a method for winding material webs, in particular foils or films, wherein during a continuous movement of the material web, a removal fork pivots the nearly full winding sleeve from a front position to a rear removal position while a new winding sleeve is moved to the winding position. The winding station is provided with a device to wind the material web automatically onto a new winding sleeve following the separation of the completed winding.

A machine (1) includes an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N), an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (Na, Nb), and at least one winding station (15). The winding station in turn includes a winding device (41, 51), to which a longitudinal strip (S) of web material is fed. In the winding station, a respective spool (B) of web material is formed. The winding station (15) further includes: a cutting device (81, 83) for the longitudinal strip (S), to cut the longitudinal strip (S) transversely, thus forming a tail edge, which remains on the spool (B) under formation, and a leading edge; and a holding device (85) for holding the leading edge of the longitudinal strip (S), to transfer the leading edge onto a tubular winding core (T) of a new spool to be wound.

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 printing apparatus includes a printing unit that prints on a medium, and a downstream side support unit that is disposed on a downstream side in a transport direction of the medium with respect to the printing unit and includes a heater which heats the medium and suction holes which is communicated with suction mechanisms. In a case of cutting the medium, the suction mechanisms are driven so that the medium is sucked and supported by the downstream side support unit via the suction holes.

Apparatus suitable for guaranteeing a quick and automatic change of materials wound on reels, said apparatus consisting mainly of a reel-alternating mechanism combined with a mechanism for cutting and reconnecting the reeled material.

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.

The invention relates to an apparatus and method for cutting a material web in a papermaking machine. The apparatus includes a cutting device, an upper holding device and an upper positioning device. The cutting device is fixed above the upper positioning device on the upper holding device such that it can be moved in the cross-machine direction. The apparatus additionally has an air guide box and the air guide box is fixed above the material web, likewise on the upper holding device. Furthermore, the apparatus has a cutting table fixed to a lower holding device via a first and/or a second lower positioning device. The cutting table is movable substantially vertically with respect to the material web via the first lower positioning device and/or movable in the cross-machine direction via the second lower positioning device.
