Problems solved by technology

In addition, when the rigidity of the packaging material is insufficient, the force received from the folded edge is concentrated only on a part of the side fence, and this force may not be effectively transmitted as the force for folding the side fence.
In this condition it is difficult to get the sideguards to fold in correctly along their regular fold in lines

Embodiment Construction

[0038] Such as figure 1 As shown, the filter cigarettes are packaged, for example, in a box-shaped hinged-lid box P. A folding-lid type case P serving as an outer package of filter cigarettes has a case main body B with an open upper end, and an inner package of filter cigarettes can be accommodated in the case main body B. The lid L is connected to the rear wall (not shown) of the box body B through a self-hinge, and the upper end opening of the box body B can be opened and closed by turning around the self-hinge. In addition, the front side opening edge of the box main body B is defined by the inner frame F, and the lid L is placed on the inner frame F when the lid L is closed. For example, 20 filter cigarettes are housed in bundles in the box main body B, and these filter cigarette bundles are wrapped in the inner packaging material to become the inner packaging product IB. As shown in the figure, when the lid L is opened, a part of the inner packaging product IB is expos...

Abstract

A wrapper folding apparatus of a packaging machine has a second wheel (10) for use as a folding turret. The second wheel (10) is supplied with a cigarette bundle and an aluminized sheet (S) in an inlet position. As this is done, the aluminized sheet (S) is folded around the periphery of the cigarette bundle, and lug portions formed by the peripheral folding are folded by means of primary lug folding guides (36). Since the lug protions are kept folded by means of holding guides (38) thereafter, they cannot be freed until an outlet position is reached. When the cigarette bundle is discharged in the outlet position of the second wheel (10), the lug portions on the end-flap side are folded by means of secondary lug folding guides (46). After the folding, side flaps continue to be folded without allowing the lug portions to be free.

Description

technical field [0001] The present invention relates to a packaging material folding device for folding a packaging material around a product in a folding packaging machine. Background technique [0002] For example, products such as cigarettes and filter cigarettes are packaged in units of a predetermined number. The package has traditionally used an inner package to maintain the taste and quality of the cigarette and an outer package that expresses the cigarette brand on the outside. In addition, these cigarette packages that have undergone inner and outer packaging must be finely packaged with an outer packaging film. Among them, for example, composite paper made by laminating metal foil such as tin foil or aluminum foil excellent in quality retention function to paper is suitable as an inner packaging material for directly packaging cigarette bundles. Materials containing such metal foils are highly malleable, easy to fold, and have the property of naturally maintainin...
