A device for loading at least one carcass drum with tire components for green tires, a tire-building machine and a method for producing green tires. The device for loading the at least one carcass drum with tire components includes a placing device, which can move linearly in the horizontal direction, for delivering material components to a carcass drum, wherein the at least one placing device can be moved vertically so that a vertical movement in addition to or alternatively to the horizontal movement is facilitated and, in this way, the ply server is designed to be self-opening.

A working system includes at least one movable apparatus movable and at least one stationary apparatus. The movable apparatus includes a working unit performing a predetermined work. The stationary apparatus includes a control unit performing drive control of the working unit. A control method of the system includes: instructing, when the movable apparatus has reached a working position, the control unit of the stationary apparatus to establish communication with the working unit of the movable apparatus; updating status information indicating a communication establishment status, after the communication instruction; instructing the control unit to transmit an operation signal to the working unit in the working position; instructing the control unit to disconnect the communication, after the signal transmission instruction step; and updating the status information after the disconnection instruction.
