Abstract

Apparatus for packaging articles in film material includes a frame structure and a mechanism for wrapping film material around a stationary article received in the frame structure. The mechanism includes a rotatable frame assembly mounted for rotation in the frame structure and apparatus for rotating the same. A roll of film material is mounted on the rotatable frame assembly along with braking and diverting rolls. A gripping device is provided to selectively engage and release the film material during rotation of the rotatable frame assembly. The rotatable frame assembly is itself mounted in a support frame arranged in the frame structure for reciprocating movement in up and down directions, i.e., the support frame carrying the rotatable frame assembly can be raised and lowered. A cut-off and seaming device is provided for cutting the film material and for seaming or affixing the cut-off end thereof. A pressing device is arranged to be descendable onto the article being packaged.
