Embodiment Construction

[0039] figure 1 The adjoining regions of the two zones ( Z1 , Z2 ) of the pressure bonding roller shaft ( 110 ) and the resulting zone contact points ( 141 ) are shown in a cross-sectional illustration. Exemplarily, the force loading devices of these zones are illustrated.

[0040] figure 2 Two zones ( Z1 , Z2 ) of the pressure-adhesive roller ( 110 ) are shown in perspective view with different force application devices ( 120 ) and an exemplary drawn diagram of several disc elements ( 130 ). In this exemplary embodiment, the cross-section of the pressure-adhesion roller ( 110 ) is embodied as a rectangle with chamfered edges.

[0041] image 3 Two zones (Z1, Z2) of the press-on roller (110) are shown in perspective view, with different force loading devices (120) and a plurality of disc elements (130) under the force set by At least some of the force loading devices in the loading device (120) are in a final position after force loading.

Abstract

The invention relates to a pressing device for tire-building machines, comprising a pressing device axis, a plurality of disk elements (130), and at least one force application device (120) for applying force to at least one of the disk elements (130), wherein the pressing device is divided into at least two zones (Z1, Z2) and the zones are equipped with force application devices of different types such that a surface pressure made uniform or a surface pressure gradient can be applied to a tire semifinished-product web in some regions by means of the plurality of disk elements (130).

Description

technical field [0001] The invention relates to a pressing device for a tire building machine with a pressing roller and a plurality of disk elements and at least one force application device for effecting the application of a force to at least one of the disk elements on the disk element. Background technique [0002] The manufacture of eg tires for vehicles such as automobiles or motorcycles is an extremely cumbersome process consisting of a number of manufacturing and process steps. The reason for this is the complex tire construction consisting of an enormous number of different components. Furthermore, a large number of these components must be bonded together under pressure and temperature in what is known as vulcanization. [0003] Not only the finished tire, which is the final product of the tire manufacturing process, is, but also the green tire is a component which is complex and consists of a number of semi-finished elements. Due to the complex structure, these...
