A banding apparatus with a ball-type, reciprocally movable web gripping mechanism cooperable with a web transfer mechanism for gripping one end of a web. The web gripping mechanism extends the web across the open end of a banding chute. A stack handling member is mounted for reciprocal movement in the chute between a normal upper position and a lower position. When the member is moved to its lower position, it acts as a support for the stack and a guide for the web. When the member is moved to its upper position, it elevates a completed bundle into position for transfer from the banding apparatus. With regard to the method steps involved to form a completed bundle, a stack of articles is moved into engagement with the web and support member, and then inserted into the banding chute through the open end thereof for moving the member to its lower position. The member is provided with guides which during downward movement of the member extend upwardly for guiding the web around the stack of articles. After the stack is fully inserted into the chute, the web gripping mechanism releases the end of the web and folds it partially over the top surface of the stack. A heating arm moves a portion of the web extending between the stack and the web transfer mechanism to a position overlapping the web end for sealing the two together. A web cut-off knife cuts the web from the web transfer mechanism providing a web flap which is blown by an air jet to the opposite side of the seal.

Apparatus for banding a stack of articles

A crank mechanism for imparting reciprocal lineal movement to a member through forward and reverse strokes, and providing dwell periods for the member at each end of its stroke. The crank mechanism comprises a rotatable crank shaft for rotatably driving an eccentrically mounted crank pin which imparts reciprocal movement to a member via a connecting rod. A cam is provided for altering the throw between the axes of the crank pin and crank shaft at each end of the stroke of the member to provide dwell periods for the member in such positions.
