ABSTRACT:
A device for braking the rotation of a rotating roll of a sheet material such as paper, cardboard, or the like, when the reeling of the sheet material has been completed. The device is used in connection with a machine which has a rotary reel spool which rotates about its axis during reeling of sheet material thereon. Adjacent one end of the reel spool is a carriage, and both the carriage and the reel spool are guided for free movement along parallel paths perpendicular to the axis of the reel spool so that the carriage can be maintained along the axis of the reel spool during building of the roll of the sheet material thereon. The braking device includes one part which is fixed to the end of the reel spool which is adjacent the carriage while the remainder of the braking device is carried by the carriage for movement with respect thereto into cooperation with the part of the braking device which is fixed to the end of the reel spool so that when the braking device operates it will act through the part of the braking device fixed to the end of the reel spool in order to retard the rotation of the reel spool with the sheet material wound thereon.
