The invention pertains to the field of industrial machinery for converting paper and/or for processing strip materials, and relates to a paper mill rewinder for forming reels of paper strip material, in particular, but not exclusively, tissue paper, of conventional or structured type, non-woven, TAD (Through Air Drying), or other similar materials characterized by having a very light weight and low density, with continuous, or non-stop, reel change device. Said rewinder (1) comprises: a supporting frame (3); feed means (4) for a winding rod (A); a main forming cradle (C1) for a reel (B) around said winding rod (A), comprising a first (5) and a second (6) winding roller; means for unloading (7) said reel (B) once formed; a control unit, a secondary pre-forming cradle (C2) for said reel (B), comprising a third winder roller (8) and lateral supporting means for said reel (B); means for transferring said reel (B) from said secondary pre-forming cradle (C2) to said main forming cradle (C1), where said transfer takes place without interruption to the winding, of the strip (N) onto said rod (A).

A medium transport device 29, a liquid ejection device 13, and a post-process device 15 include a recording path 38; a first transport path 40 arranged downstream of the recording path 38; an inversion path 39 arranged downstream of the recording path 38; a first branch section 51; and a blower section 50 configured to transport the medium 19 to either the first transport path 40 or the inversion path 39, wherein when a medium 19 that is transported first is defined as a first medium and a medium 19 that is transported subsequently to the first medium is defined as a second medium, in a case where the blower section 50 switches a transport destination between the first medium and the second medium, the blower section 50 starts the switching operation while the first medium is passing through the first branch section 51.

A method and apparatus for the production of coreless paper rolls, including a winding phase on a central spindle of a paper web carried out by a main reel, until the formation of a wound paper roll, a phase of extraction from the wound roll of the spindle by application of a relative axial extraction force between the roll and the spindle, where the winding phase includes a first winding phase of a number of web revolutions on the central spindle performed at a first winding tension that is lower than the next winding tension.
