<p>First(1) and second(2) grippers hold the first and second tool shells and are movable along an axis(6) relative to each other and to a centering station(3). Individual or synchronous rotation around the axis is also possible. The centering station includes one or more springs surrounding a circular opening through the center of which the axis runs. The centering station(3) comprises a block with a wall which surrounds the circular opening and includes a groove. Springs can be a closed or open O-ring or a tube made of an elastically deformable material which is placed in the groove. An alternative spring comprises tabs located around a ring. Both grippers(1,2) are mounted on a common guide rail(7). First(8) and second(9) motors move the gripper along the axis(6). Third(10) and fourth(11) motors rotate the grippers around the axis. A dispensing mechanism applies a tape for joining both shells. Both grippers rest on a support with a seal on the inner side for sealing a chamber between each gripper and a tool shell. A flexible component permits movements of the seal along the axis to accommodate tool shells of different shapes.</p> |
