<p>A tool positioning device (10) for use in combination with a machine (12) for working paperboard blanks (B) conveyed in a horizontal direction through the machine. The machine (12) includes pairs of parallel rotary shafts wherein each pair of shafts includes upper (S1) and lower shafts (S2) and carry a plurality of tool heads (H1, H2). The positioning device includes a plurality of coupling members (50, 52, 54, 56) actuated in a vertical direction by actuators (34, 36, 38, 40) wherein the coupling members are moved downwardly into engagement with the tool heads. The coupling members (50, 52, 54, 56) are supported on an actuator support (22) which is mounted to a transfer structure (18, 20, 24, 26, 28, 30) wherein the transfer structure moves the actuator support in axial movement to thereby slide the tool heads along their respective shafts to preselected positions along the shafts.</p> |
