A method is disclosed for winding one or more layers of strip material (5) under predetermined tension around a tubular element (8), for each layer the strip material (5) being taken from the inside of a buffer reel (3) which is arranged around the tubular element (8) to be wound, while the tubular element (8) is displaced axially and the buffer reel (3) is driven so that it rotates, clamping means (10) situated in a rotary casing (9) around the buffer reel (3) also being present for clamping the end (11) of the strip material (5) present on the buffer reel (3), while the buffer reel (3) is provided periodically with a new buffer of strip material. Prior to the connection of the end (11) with the end (13) of a new length of strip material the casing (9) is driven so that for a predetermined duration it rotates at a higher speed than the top layer of the strip material (5) on the buffer reel to form a play. Thereafter the casing (9) is stopped and the end (11) of the strip material (5) on the buffer reel (3) is connected to a new length (13) of strip material, and the buffer reel (3) is filled. During the connection the winding process is continued. After filling of the buffer reel the end of the strip material (5) is again clamped by the campling means (10). Also a device disclosed for carrying out the above method. |
