Japanese Patent JP2016078887
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a laminate tube, without causing delamination of a laminate thereby, when melting a metal vapor deposition layer off a shoulder port of the laminate tube, in the laminate tube of including a metal vapor deposition film in the laminate for constituting a trunk part.SOLUTION: In a manufacturing method of a laminate tube for constituting a trunk part of a laminate of including a metal vapor deposition film, the manufacturing method of the laminate tube is provided for forming a shoulder port of a tube in an end part of the trunk part, by forming the trunk part so that an end surface turns to the inside by push-cutting by two or more of arc-shaped cutters from above the laminate formed in a cylindrical shape, by inserting a mandrel, after being formed in the cylindrical shape by executing a side seal of the laminate.SELECTED DRAWING: Figure 1
