Abstract

A device for sidewise alignment of a flat workpiece on a table includes a lower pull member for moving a flat workpiece toward a side stop and a pad for pressing the flat workpiece onto the pull member. The pad is fitted above the pull member on a bar that is lowered when the flat workpiece is applied against a front stop, and this pad is movable in translation along an axis parallel to the pull member. A spring urges the pad back to its initial position when the bar is raised to disengage the pad from the surface of the workpiece. The pull member and bar extend over the whole width of the table and the pull member is arranged in a groove made along an upper surface of a crossbar of the table, whereas the sides of the bar are held by ends of lever arms which are mounted for rotation on sides of the table frame.

Dependent claims

In a device for lateral alignment of a flat workpiece on a table, said device including lower means for carrying the flat workpiece toward a side stop, upper means for pressing the flat workpiece onto the lower means, and support means for mounting the upper means above the lower means including a bar supporting the upper means and means for lowering the bar, the improvements comprising the lower means including a pull member movable toward the side stop when the bar is lowered;

the upper means including a pad, pad mounting means for mounting the pad for movement in translation along an axis parallel to the pull member so as to follow the motion of the flat workpiece and the pull member when said pad is pushed against the flat workpiece by the bar, and elastic means for acting on the pad to return the pad to an initial position when the bar is in a raised position to disengage the pad from the workpiece;
and control and actuator means for moving the bar and pull member.
