First Claim
1. In an adhering device of the type including a roll of long, narrow, continuous package, a means for feeding the continuous package to a cutter, a bucket wheel from picking up the commodity and transferring the commodity to an adhering position and means for transferring the cut continuous package to the adhering position and for adhering the cut package to the commodity, said means for transferring and adhering comprising:
- a vacuum transfer device comprising;
a rotatable transfer drum;
a plurality of suction pipes provided uniformly about a periphery of the transfer drum;
a source of compressed air;
a void chamber provided in said drum;
a plurality of Venturi tubes for generating a vacuum provided in said void chamber and communicating each with a suction pipe; and
a pressure chamber provided in said drum to which said compressed air is supplied and which supplies compressed air to each of said Venturi tubes; and
