FOLDABLE SHEARED SHEET CASSETTE

PURPOSE:To improve convenience for carrying and storage of a sheared sheet for seal-packing powder and particle materials by an automatic binding device. CONSTITUTION:A foldable sheared sheet cassette comprises a cylindrical sheared sheet 5 made of flexible plastic which has been folded into axially stretchable bellows placed on an outer peripheral face of a cylindrical core 2 made of cardboard or an elastic plastic. An end of the sheet is inversely passed through a hollow part from an upper opening of the core 2 while the sheet is being stretched and pulled out from a lower opening to form a bag with a bottom, after an object to be packed is put in the sheet formed as a bag, the sheared sheet above the object is gathered to seal the object, and the gathered part is cut off to manufacture a sealed packing bag of the object. Then a flatly deformably cylinder with the core 2 comprising a plurality of arc members 3 which can be coupled foldably to one another is formed.
