Claim:
A device for splicing the free end of a strip of web material to a homologous strip of web material being supplied, the device comprising: a first moving element and a second moving element, each of which is able to function alternatively as retention structure for said free end and as guiding structure for said web of material being supplied, said first moving element and said second moving element being, at least in part, translatable with respect to one another for connecting said free end to said web of material being supplied; and wherein each of said first moving element and said second moving element is selectively orientable between: a position of opening, in which one of the moving elements has a gripping formation for said free end exposed to receive said free end; a position of closing, in which said gripping formation faces the other of the moving elements of the device for enabling a connection of said free end to said web being supplied; and wherein said first moving element and said second moving element carry associated thereto a mechanism of orientation between said position of opening and said position of closing, said mechanism comprising: a rotary actuator, which can turn about an axis; an arm, which can be driven by said actuator in a movement of slewing about said axis and carries at its distal end a follower element; and a cavity for sliding of said follower element, said cavity for sliding being fixed with respect to the respective moving element.
