Abstract: Winder (1) for continuous web material, comprising: a motor-driven winding cylinder (13), a rod-holder structure (4), and at least one elastic element (7) for protecting said structure (4) against possible contact pressures greater than a preset value (P).
Abstract: An apparatus for reel replacement in machines for the production of reels of light-weight web material, of a type with a device for winding material onto a tubular core or rod and a device for feeding an unloaded rod (spool) intended to replace the reel. The apparatus has a surface (80) able to delimit, in cooperation with the surface of an unloaded rod (51), a channel (85) to which a jet of air produced by a plurality of nozzles (9) is directed.
