Abstract
The present invention relates to a method and device for the transferring of a web onto a reel spool in the reel-up of a paper web having an empty reel spool (2) that is introduced into a contact with the web (W) running on the reeling cylinder (1) and being still unreeled, to make the transfer possible, and a turn-up blow is used to help the web (W) to break and to be guided on to the empty reel spool (2). The turn-up blow is brought from beneath a horizontal plane passing through the central axis of the reeling cylinder (1) into a location on the mantle of the reeling cylinder that is located after the reel spool (2) in the direction of rotation of the reeling cylinder.
Claims12
A device for transferring a paper web onto a reel spool in a reel-up of a paper web, comprising:
- a reeling cylinder (1) structured and arranged to be rotatable around a center axis, said reeling cylinder (1) being structured and arranged to guide the paper web (W) on a mantle thereof,
- means for bringing an empty reel spool (2) into contact with the paper web (W) running on the mantle of the reeling cylinder (1) to thereby make the transfer possible,
- a support frame structured and arranged to be movable into an operating position, said support frame having:
- a nozzle structure (4a) operatively coupled to an end thereof;
- and
- an air channel (4) structured and arranged to supply air to said nozzle structure (4a);
- said nozzle structure (4a) being directed towards the mantle of the reeling cylinder and located after the empty reel spool (2) in the direction of rotation of the reeling cylinder (1), said nozzle structure (4a) being structured and arranged to effect a transfer of said web (W) from said reeling cylinder (1) to said reel spool (2) by effectuating a turn-up blow on said mantle of said reeling cylinder (1), wherein when said support frame is in the operational position, the support frame and the air channel (4) supplying air to the nozzle structure are brought from below a horizontal plane passing through the central axis of the reeling cylinder, to the vicinity of the mantle of the reeling cylinder (1).
A method for transferring a web onto a reel spool in a reel-up of a paper web, comprising the steps of:
- providing a reeling cylinder (1), wherein said web is run over said reeling cylinder rotating around a central axis and said web being unreeled;
- providing an empty reel spool (2);
- bringing said empty reel spool (2) into contact with said web (W);
- and
- providing a turn-up blowing onto said web for breaking said web and for guiding said web onto said empty reel spool (2), wherein said turn-up blowing is introduced from beneath a horizontal plane passing through the central axis of said reeling cylinder (1) and is effectuated on a portion of the mantle of said reeling cylinder located after said contact point with said empty reel spool (2) in a direction of rotation of said reeling cylinder.
