Embodiment Construction

[0032] Figure 1A Schematically shows a side view of a plant for manufacturing green tires. The plant has a first building drum 1 , a second building drum 2 and a transfer device 3 and a transfer ring 4 .

[0033]In the example shown, the first building drum 1 is a combined carcass and building drum (building and building drum). Said substantially cylindrical building drum 1 having a substantially horizontal outer circumferential surface has a crimping device, known per se, for crimping edge portions of tire components arranged on the drum in the direction of the center of the drum 1 . Said other crimping devices are known, for example, from patent publication WO 01 / 68356, which uses radially extending articulated arms for this purpose, or WO 03 / 013835, which uses radially expandable articulated arms for this purpose. The inflatable rubber bladder is not further described here so as not to unnecessarily obscure the subject matter of the present invention.

Abstract

Method and assembly for manufacturing a green tyre using a building drum (1) and a transfer device (3). The method comprises a step of arranging and forming a first tyre component assembly for the green tyre on a building drum (1), a step of placing the transfer device (3) around the building drum, a removal step of the first tyre component assembly for the green tyre being removed from the building drum (1) by the transfer device (3). After the removal step second tyre components for the same green tyre are arranged on the building drum (1), followed by a step of placing the transfer device (3) around the building drum (1), and a step of placing the first tyre component assembly on the second tyre components.

Description

technical field [0001] The present invention relates to a method and assembly for manufacturing unvulcanized or green tires utilizing a substantially horizontal building drum and transfer means. The method comprises the steps of positioning and forming a first tire component assembly for a green tire on a building drum, the steps of placing a transfer device around the building drum, and removing the first tire component for a green tire from the building drum by the transfer device Component removal steps. Background technique [0002] Several different building drums are utilized in the manufacture of green tires, and the components of the green tire are transferred from the first building drum to the second building drum, for example from NL 2001071, US 2010 / 0000662, and US7.520.949 known. The assembly described therein includes a belt building drum (cutting drum), a carcass building drum, and a building drum, wherein each drum is optimized for performing a portion of t...
