ABSTRACT:
An apparatus for wrapping objects in heat-sealable film which provides for continuous mechanical wrapping of objects and which is suitable for wrapping objects which have poorly-defined shape or which are non-uniform in size or shape is described. The apparatus of the invention comprises a frame; a conveyor assembly for advancing the film and the object and for bringing the film into a wrapping relationship with the object; a sealing assembly for bringing the sides of the film having the object contained therein into heat-sealable contact and for sealing the film to sealably enclose the object; an indexing carriage for advancing the sealing assembly at the same rate as the conveyor assembly; and means for sensing the object and activating the sealing assembly to seal the film.
