Abstract

Abstract An automatic packing and wrapping apparatus for wrapping articles such as blocks of meat, comprising an assembly for forming a strip of synthetic resin film into a tubular shape, an assembly for feeding the article into the tubular film through nozzles, and an assembly for tying the ends of the film so as to seal the article in the film. The nozzles include a crushing mechanism comprising, for example, a rotary cutter and a fixed cutter each secured to the end of a respective nozzle. The article is crushed by the crushing mechanism at predetermined intervals to form alternate bulky and slender portions for every given length of the article in the film. The article portions within the film are pinched and squeezed by a pair of pinch rollers, and then the surrounding film is tied with metal clips or the like.
