ABSTRACT:
An applicator (10) for applying a string or tape (72) coated with a thermoplastic adhesive to a moving substrate (14) is the subject of this patent application. The applicator (10) includes a first roll (28) about which the string (72) is fed. Thereafter, the string (72) is led over a second roll (30). The string (72) is, successively looped about both of the rolls (28, 30) a number of times. One of the rolls (28) is heated by use of a plurality of heating elements (26) embedded in a casting (24) surrounding the roll (28). The second roll (30) is pivotable about an axis and in a plane generally parallel to an axis of elongation of the first roll (28). Loops of the string (72) can, thereby, be spaced axially along the rolls (28).
