ABSTRACT:
Apparatus for packaging of drinking straws. A cylinder having notches extending longitudinally thereof is positioned at the lower end of a hopper for the straws. The hopper has a supply conduit terminating in an outlet closely overlying the surface of the cylinder. The straws pass into the supply conduit in parallel horizontal positions to define an endless column. A feed mechanism compresses the straws within the supply conduit so that individual straws are forcefully engaged with the notches in the cylinder. A first web is fed onto the periphery of the cylinder in overlying relation to the notches and when a notch, covered by the first web, moves into alignment with the outlet of the supply conduit, a lowermost straw is forced from the supply conduit into the notch while deforming the web to the general configuration of the notch. A second web is fed into overlying relation with respect to the cylinder and the first web to hold the straws depressed within the notches until edges of the webs are bonded together.
