Problems solved by technology

[0006] A disadvantage of the transfer device according to WO 2012 / 072932 A1 is that the active circumferential area is not limited to places where suction is actually required to hold tire components
Thus, during continuous application, only a part of the tire component is held along a limited circumferential area of ​​the transfer device, the uncovered area of ​​the transfer device leading to considerable pressure losses
Moreover, the angular position of the chamber of the housing cannot be adjusted to accommodate different process conditions, i.e. changes in the angular pick-up of (a part of) the tire component and / or the second holding position

Embodiment Construction

[0070] figure 1 - 3 shows an application roller 1 or an application roller for applying a strip S to a drum, in particular a tire building drum D, according to a first exemplary embodiment of the invention.

[0071] Figure 2A - H and 3 show the application roller 1 as part of a tire building station, in particular a tire component feeder 700 . The tire component feeder 700 comprises an extruder 705 having an extruder die 750 for extruding a strip S along an extrusion direction E. The application roll 1 is located directly downstream of the extruder die 750 in the direction E of the extruder.

[0072] The tire component feeder 700 also includes a sensor 704 for detecting the presence of the strip S on the application roller 1 and a knife 406 for cutting the strip S to length at or near the extruder die 750 .

[0073] Figure 2A - 2H shows the steps of the method for producing a strip S and applying said strip S to a drum D. Such as Figure 2B As shown in , the strip S h...

Abstract

The invention relates to an application roller, a tire component feeder and a method for applying a strip to a drum. The application roller comprises an outer ring rotatable about an axis of rotation and defining a holding surface, wherein the application roller is provided with a suction opening for holding the strip on the holding surface, wherein the application roller comprises a follower rotatable inside the outer ring to follow a portion of the strip on the holding surface, wherein the follower defines a chamber, and the chamber extends in a circumferential direction over a retention arc along the outer ring, and wherein the follower is rotatable independently of the outer ring about the axis of rotation to a first retention position on the outer ring in which the chamber is arranged in air communication with one or more suction openings within the retention arc.

Description

technical field [0001] The present invention relates to an application roller, a tire component feeder and a method for applying a strip to a drum (drum). Background technique [0002] DE 27 40 609 A1 discloses an applicator serving as an intermediate carrier for an applied layer, having at its periphery a suction cup connectable to a vacuum source. The applicator has a housing enclosing an annular chamber which is circumferentially sealed by two dividing walls mounted alternately to the drum and the housing. The annular chamber is connected to a vacuum source. As the head of the layer moves onto the applicator, the drum remains stationary while the housing rotates, moving the two dividing walls apart step by step at the same rate as the layer is fed around the housing. Thus, the suction cup of the applicator is only connected to the vacuum source along the progressively increasing circumferential area of ​​the housing defined by the partition wall. In this way, pressure ...
