ABSTRACT:
A device for moving objects (4), such as die tools or molds, to and from the table (2) of a press (1) comprises a bar (24) being vertically movable, by means of inflating a bag (10), from a first position in which an upper surface (26) of the bar (24) is located below the upper surface (16) of the table (2) to a second position in which the upper surface (26) of the bar (24) is located above the upper surface (16) of the table (2). The bar (24) is adapted to slide horizontally in its longitudinal direction and is provided with gear teeth (28). A gear wheel (32), engaging the gear teeth (28) of the bar (24), is adapted to move the bar (24) in the horizontal direction along the slot (14) when the bar (24) is in its second position and thus to move an object (4) resting on the upper surface (26) of the bar (24).
