Device and method for producing green tyres

A tire building machine for producing tire blanks, said tire building machine comprising:

• a rotary table having a vertical axis around which the rotary table is pivotable;
• a double-drum carcass machine arranged on the rotary table and disposed so as to be pivotable with the rotary table in a horizontal plane, wherein the double-drum carcass machine includes two carcass machines each having one carcass drum;
• and at least one ply server for feeding the double-drum carcass machine with tire components for tire blanks, wherein the at least one ply server has at least one placing device and is configured so as to open and is disposed so that the at least one placing device in a loading position protrudes into a kinematic moving area of the double-drum carcass machine, wherein the at least one placing device is movable in a linear manner in a horizontal direction for supplying material components to the carcass machine, wherein the at least one placing device is movable vertically so that, additionally or alternatively to the horizontal movement, a vertical movement is facilitated and thereby the ply server is configured to open, wherein the at least one placing device is formed by an upper placing device and a lower placing device, wherein the upper placing device and the lower placing device protrude in the loading position into the kinematic moving area of the double-drum carcass machine, and wherein the rotary table is configured so that pivotable movement of the rotary table is interruptable in at least one loading position.
