An apparatus for continuously winding a web of sheet material into rolls comprises a turret mechanism (1) comprising two or more winding mandrels (2,3,4,5). The turret mechanism (1) is rotatably indexed to bring each mandrel (2,3,4,5) in turn into a winding position in which it is rotatably driven to wind a web of sheet material (8) connected thereto into a roll, and to bring the adjacent mandrel lying immediately behind it in the direction of rotation of the turret into contact with the web (8). The said adjacent mandrel is rotatable. Rotary means (11) is adapted for selective engagement with the said adjacent mandrel, which rotary means (11) is rotatably driven in the opposite direction to the said adjacent mandrel and at a greater speed. The apparatus further comprises web cutting means (16) adapted to cut the web (8) at a point lying between the current rewind mandrel and the said adjacent mandrel. The cut end of the web is directed by the cutting means between the adjacent mandrel and the rotary means (11), such that by rotating the said adjacent mandrel through a few turns the web is wrapped around it. The turret is then indexed forward to move the said adjacent mandrel into the rewind position.
