Abstract (en)
An apparatus for winding webs of paper or similar material on a core (A) including a first rotary winding roller (1), along which a web material (N) is driven. A second rotary winding roller (3), forms a nip (5) with said first winding roller (1) to receive a core (A1). A pusher (12) inserts a core (A1) into the nip (5). A movable roller (7) controls the diameter of the roll (R) or log in the course of formation between said three rollers (1, 3, 7). Only the second roller (3) is arranged to have a variable speed and to slow down during the insertion of a core (A1) into said nip (5). An adhesive applicator (20) is provided to wet the cores (A) with glue before being inserted into said nip (5), and a take-off surface (9) near said second winding roller (3) extends away from the exit of said nip (5).
