ABSTRACT:
The present invention relates to an apparatus for decelerating the jumbo roll of a paper or a board manufacturing machine in order to minimize the time required for a reel drum exchange and the amount of paper or board wasted as the jumbo roll slackens. The apparatus comprises brake shoes (9, 11) and arms (8) provided with means (13) producing the decelerating force. The arms can simultaneously transfer and decelerate the jumbo roll (2) whereby also a loop in the web is formed rapidly and easily.
