FIELD: machine building.
SUBSTANCE: invention refers to machine for fabrication of closed item containing first device for direction and for retention of material of tyre positioned inside first device. The distinguished feature of the invention consists in capability of the first device to controlled change of a shape between the first and the second shape. Also the invention refers to the machine for fabrication of the closed item containing the first device for direction and for retention of material of the tyre positioned around the first device and characterised with additional sixth device for tyre material bending. The sixth device consists of multitude of bending elements movable relative one to another. Notably, the bending elements interact with material of the tyre and bend it. The bending elements travel inside recesses made in the first device for this purpose.
EFFECT: improved welding, bending, and treatment of tyre materials.
