Embodiment Construction

[0046] figure 1 The device is shown in a basic position. The device comprises a building or carcass drum 5 , which is rotatably arranged on a drive shaft 11 . The drive shaft 11 is rotatably installed in the spindle box 7 and driven by the motor M5. The dashed line 15 shows a possible wider building drum, which can likewise be arranged on the drive shaft 11 , eg for larger tire sizes. Arranged on both sides of the building drum 5 is a left airbag holder 3 and a right airbag holder 6 . The right airbag carrier 6 is moved in its axial position along the shaft 11 by the electric motor M3. The axial position of the airbag carrier 6 depends on the tire carcass which is subject to corresponding requirements. The diameter adjustment of the balloon support in the radial direction 13 is carried out by means of the electric motor M4. The balloon holders 3 and 6 are equipped on their outer circumference with inflatable balloons which wrap, inter alia, the insertion ends around the t...

Abstract

The invention relates to a device for constructing a carcass for a vehicle tire. In order to provide a device with which the core centering devices can be expanded variably in diameter, wherein the core centering devices can be used at the same time for producing small tire dimensions, and with which at the same time the diameter of the diaphragm supports can be moved by a motor, it is proposed that the diaphragm support (3) on the side of the movement box (1) be connected to the shaft (10) of the movement box (1) in a fixed manner, wherein the axial distance for determining the carcass width of the vehicle tire to be produced between the diaphragm support (3) and building drum (5) occurs through positioning of the movement box (1) in the axial direction (12), and the diaphragm support on the side of the headstock is movably attached to the shaft, wherein the axial distance for determining the carcass width of the vehicle tire to be produced between the diaphragm support (6) and building drum (5) occurs through positioning in the axial direction.

Description

technical field [0001] The invention relates to a device for building a carcass for vehicle tyres. Background technique [0002] In tire production, building drums are used to produce tire carcasses. On such building drums, individual tire building components in the form of rubber plies with reinforcing elements are wound and assembled. In one of the method steps, the tire cores with bead fillers are positioned in place and the inserts are then wrapped around the tire cores. Subsequently, the tire carcass is removed from the building drum and processed further on another device. [0003] A disadvantage of conventional building drums for producing tire carcasses is that these core centering devices are not suitable for small tire sizes. One of the reasons for this is that the minimum diameter of the centering device is governed by the maximum diameter of the shaft on the side where the moving box is located. Arranged on the shaft end of the travel box is a so-called airba...
