Patent

CA 2111677

A method for wrapping a roll (1), particularly a paper roll, in a continuous wrapper web (2) of elastic material such as a paper web wrapper or plastic film, in which method the wrapper material web (2) is wrapped about the roll by rotating the roll (1), and further, in which method the wrapper material is tensioned by means of a braking arrangement (8) adapted to the essentially immediate vicinity of roll. The invention is implemented so that the wrapper material web (2) is tensioned essentially during the entire time of its wrapping about the roll (1) to be wrapped and that, just prior to the braking arrangement (8) of the web (2) on the machine direction path, the wrapper material web (2) is slackened, in practice into a wave, (10), whereby the wrapper material web assumes a tensional equilibrium attitude (11) in the web cross direction and whereby the wrapping can take place in a slightly spiralling manner (13).
