FIELD: paper.
SUBSTANCE: invention relates to a rewinder for making paper logs. Rewinder comprises feeder configured to feed paper web, guide means configured to guide successively several cores along preset path between core feed station and winding station, in which preset amount of web is wound on each core. At that, reeling device is made with possibility of paper web winding on cores in winding station, and guide means comprises guide with bent end section. Curved end section of the guide terminates at the winding station and, in interaction with the winding device, limits the channel crossed by each core until reaching the winding station. At that, rewinder comprises facility made with possibility of cyclic change of guiding end section shape during winding of web on cores so that height of end part of channel varies cyclically between minimum preset value and maximum preset value. End part of the bent end section of the guide is connected to the drive, which controls its movement synchronously with the winding device, at that cyclic change of height is determined by controlled movement of the specified end part of the bent end section.
EFFECT: rewinder allows to produce qualitative paper logs characterized by more uniform distribution of paper in radial direction.
