ABSTRACT:
An apparatus for tubularly covering each of a plurality of trays containing a packaged object with film while elongating the film itself. In the course of conveying each tray in the longitudinal direction of the tubular film, the film itself is cut off between a pair of adjoining trays aligned in the front and on the back. Simultaneous with execution of a cutting operation, a pair of edges of the tubular film are respectively subject to vacuum by vacuum absorptive force in a pair of suction tubes each being disposed on the up-and-downstream sides of the cutting unit. The suction tube on the downstream side is transferable in the direction identical to the direction of conveying these trays. The suction tube on the downstream side returns to the original position by the time at which the following tray arrives at this position.
