The adhesive weight elements (8) in the form of an endless weight strand (5) are fed by a feed device (2) arranged on the balancing head (1) to a following roll-on roller (3) that presses the beginning of the endless weight strand (5) onto the beginning of the compensation surface (17) and thereafter rolls along thereon. A length cut-off device (4) is provided in or before the roll-on roller (3) and cuts-off the endless weight strand (5) of the adhesive weight elements (8) in a determined length.

Abstract: To mount a pneumatic tire (R) on a drop base rim (F), the pneumatic tire (R) is gripped by a gripper (2), which is arranged on a handling device (1), on the tread, and the first tire bead thereof is slipped over a flange of the rim (F) by controlled movement of the gripper (2). Subsequently, the gripper (2) is released from the pneumatic tire (R), and the tire (R) is moved into an initial position for mounting the second tire bead by adjustment members (33, 34). Mounting tools (27, 28, 29) arranged on the gripper (2) are guided along on the rim (F) by rotating the gripper (2) about the axis of the rim (F), resulting in the second tire bead being slipped over the rim (F).
