  • the scope of the invention also includes the idea according to which both the press device forming the actual reeling nip and the press device forming the additional nip in the change situation are pneumatic press devices, which are both implemented by means of an air blowing front directed from one or several nozzles in a suitable manner.
  • Fig. 4 shows an embodiment in which the flow of air of the air press device is not guided directly against the surface of the reel, but the linear load of the air press device is transmitted to the surface of the reel through a special transmitting material, which may be a suitable flexible elongated supporting element moving in the travel direction of the paper web.

  • FIG. 5 also shows two towards each other directed slot-like nozzles 1b, between which a shared carrier surface 1c of the nozzles is formed. It is also possible to provide the press device with only one slot-like nozzle 1 b that is directed either in the travel direction of the web or against the travel direction of the web.

All the arrangements according to Figs 1 to 5 can thus be applied also to the winding of customer rolls, and the web W shown in the drawings can be considered as a part web obtained from a full- width web after the slitting operation.
