ABSTRACT:
The invention provides an arrangement for delivering to a work table a workpiece to be machined on that table and for removing the workpiece after it has been machined. The arrangment includes three endless conveyors in a line, of which a central, non-driving conveyor is fixedly mounted on the table between an upstream conveyor and a downstream conveyor. The upstream conveyor and the downstream conveyor are mounted on frames separate from the table and are designed for displacement between a position in which they are both remote from the central conveyor and a position in which they are both adjacent the central conveyor. The upstream and downstream conveyors rotate the central conveyor when in their adjacent position. Retractable retaining means position the workpiece received on the central conveyor and hold it on the work table throughout the entire machining operation. Means are provided for lowering the central conveyor from the workpiece during the machining operation. The arrangment according to the invention is particularly intended to be used for loading and unloading an installation for machining the edges of a flat object.
