APPARATUS FOR BINDING PACKAGING BAG OF LONG MATERIAL END

Japanese Patent JP3502501

B

PROBLEM TO BE SOLVED: To enable binding rigidly without slack and with a good package form by providing a specific pinch-fold means and a fold-down means to automatically pinch-fold and fold down ear-like excessive parts at both side ends of a packaging bag.
SOLUTION: In a pinch-fold means, when a packaging bag A is mounted at an end of a work Z, a first pinch member 11 lowers a base end of an ear-like excessive part, while a second pinch member 12 raises a tip of the ear-like excessive part to have the part pinch-folded. Although, however, the part is neatly pinch-folded onto an outer periphery of the work Z along the outer periphery of the work Z, an excessive part is formed between the tip of the work Z and a bottom of the packaging bag A mounted on the work Z. The pinch-folded ear-like excessive part is pushed up by a lever 25 sliding on a lower face of a belt 22, which is provided at the tip of an arm 21 of a rotating fold-down means, the belt 22 is fed from both ends to form a shape for grasping the work Z, and it is folded down around the outer periphery of the work Z to hold it.
