Abstract
A device for splicing strips has a first drum rotating about a first axis and having a first outer face for selectively retaining and guiding a first strip; and a second drum rotating about a second axis and having a second outer face for selectively guiding and retaining a second strip; the first and second outer face are so shaped as to form a gap for passage of the strips, and to press the first and second strip and a sticker together as a function of the indexing angles of the first and second drum.
Claims22
1) A splicing device for splicing a first strip (8) fed off a first reel (10), and a second strip (9) fed off a second reel (11);
- the device being characterized by comprising a first drum (13) rotating about a first axis (13a) and having a first face (19) for selectively retaining and guiding the first strip (8);
- and a second drum (14) rotating about a second axis (14a) and having a second face (20) for selectively guiding and retaining the second strip (9);
- the first and second face (19, 20) being so shaped as to form a gap between said first and said second face (19, 20), and to selectively press the first (8) and second (9) strip together as a function of given indexing angles of the first and second drum (13, 14).
17) A method of splicing a first strip (8) fed off a first reel (10), and a second strip (9) fed off a second reel (11);
- the second strip (9) having a sticker (45) on its free end;
- and the method being characterized by guiding the first strip (8) along a first face (19) of a first drum (13), and retaining said free end of the second strip (9) by means of a second face (20) of a second drum (14) and the sticker (45) on the second face (20) of the second drum (14);
- and rotating the first and the second drum (13, 14) about a first and a second axis (13a, 14a) respectively, to press the first and the second strip (8, 9) and the sticker (45) together and so splice the first and the second strip (8, 9).
