In a method and apparatus for transferring a forwardly travelling web of one or more layers to a take-up roller with minimal delay and wastage a rotating take-up roller 23 is provided adjacent the web 1, such that flaps 27 may divert a loop of web around the roller 23 in its direction of rotation. The movement of the loop around the roller 23 may be guided by air blast issuing from channels 28 and confined by a hood 32, or otherwise. The flaps 27 applies the web 1 against a stop 38 which restrains the web and causes it to be cut by an edge 58. The loop is guided round the roller 23 until it is pinched between the roller and a subsequent web portion, and the leading web portion is thus attached to the roller, and the web thereafter wound onto it. Once the web portion has been attached, the roller may be transferred to a take-up station 19. <IMAGE> |
