The invention relates to a machine for manufacturing an object closed onto itself, which machine comprises first means for guiding and carrying a tire material to be arranged round the first means, characterized in that the first means can change form in controlled manner between a first form and a second form. The invention also relates to a machine for manufacturing an object closed onto itself, which machine comprises first means for guiding and supporting a tire material to be arranged round the first means, characterized in that the machine also comprises sixth means for folding the tire material arranged round the first means, for which purpose the sixth means comprise a number of folding members movable relative to each other, which folding members can engage on the tire material for folding and can therein move inside recesses provided for this purpose in the first means. The invention also relates to methods for manufacturing an object closed onto itself, comprising of arranging a tire material round first means provided for this purpose. Such machines and methods can be applied particularly in the production of tires for vehicles.
Machine (1) for manufacturing a component of a car tyre, which machine comprises first means (4) for guiding and carrying a tyre material to be arranged round the first means, wherein the first means can change form in controlled manner between a first form and a second form, characterized in that the first form (4A) has a substantially cylindrical periphery and the second form (4B) a substantially cylindrical periphery with a flattened portion, characterized in that the first means comprise a plurality of radially adjustable elements (6) wherein the positions of the elements can be radially adjusted and adjusted relative to each other such that an at least partial change takes place between the first and the second form.
Method for manufacturing a component of a car tyre, comprising of arranging a tyre material (5) round first means (4) provided for this purpose, wherein the method also comprises of causing the first means to change form in controlled manner between a first form and a second form, wherein change takes place between a first form (4A) with a substantially cylindrical periphery and a second form (4B) having a substantially cylindrical periphery with a flattened portion characterized in that the first means (4) comprise a plurality of radially adjustable elements (6), wherein change between the first and the second form takes place at least partially by radially adjusting and adjusting relative to each other the positions of a plurality of elements (6) provided for this purpose, which elements form part of the first means.
