Abstract:
1. Mechanism for a machine for stapling two mouldings, comprising a table, for supporting the mouldings, and a kinematic linkage for actuating two jaws in an operating plane substantially parallel with the table, for pushing the two respective mouldings back laterally towards a respective operating position, against two side stops respectively extending in mutually inclined directions, and then after stapling, moving away from the stops and returning to a rest position, wherein the kinematic linkage comprises means for elevating the jaws arranged to displace, under the action of means for driving the means for elevating the jaws, the jaws in a direction transverse to the operating plane, so that the jaws can thus be retracted, into the rest position, outside the operating plane and in which the elevating means comprise a chassis integral with the table and a control unit slidably mounted with respect to the chassis under the action of the drive means, in a predetermined direction of sliding with respect to the table, the control unit comprising a detector of the sliding movement which is provided for driving in rotation a elevating screw, carried by the control unit and oriented substantially perpendicularly to the plane of the table, the threading of which is coupled with a nut, fixed in rotation, integral with an elevating table carrying the two jaws.
