ABSTRACT:
Two pairs of interdigitated rotatable members are arranged at right angles to one another and are connected by a chute leading downwardly away from one of the pairs and transversely to the other of the pairs so that paper can be first cut up into strips and then subsequently recut to form a confetti. The rotatable members are formed of spools coaxially mounted on a drive shaft, each of the spools being formed of circular or cylindrical members with lesser diameter portions therebetween for purposes of spacing. A comb is provided in association with at least one of the rotatable members and is provided with extra tongues accommodated in grooves formed on the rotatable members in order to strip paper therefrom in order to prevent the paper from becoming entangled in the rotatable members and jamming the same.
