Abstract: A source for supplying lengths of adhesive tape applies such adhesive elements with their outer surfaces facing outwards onto a gripping element consisting of a rotating drum. The drum in question applies the adhesive element on the outer surface of a reel of web material in such a way as to establish adhesive connection with the latter. As a result of a subsequent movement of the drum with respect to the reel, there is formed a loop of web material. Since the loop is separate from the reel, it can undergo a cutting action with the consequent formation of a free flap that can be used for unreeling the web material from the reel. After the web material has been unreeled for a certain stretch and the portion on which the aforesaid adhesive element was applied has been eliminated, on the same web material there may be applied a further adhesive element which is left uncovered for at least part of its surface provided with adhesive.
