ABSTRACT:
An apparatus for manufacturing rectangular frames composed of strips which are assembled by way of mutual joining elements which are driven into them by stapling machines so as to straddle the joints formed by mating the strips at right angles, which comprises: a horizontal beam which is supported so that it is rotatable centrally about a vertical axis so as to form two arms which lie diametrically with respect to the vertical axis, each arm being provided with sliding guides for respective carriages; two levers, which are articulated to each one of the carriages about axes which are parallel to the vertical axis; a grip element for a respective one of the strips that constitute the frame being mounted on each one of the levers; elements for actuating the grip elements, the levers, the carriages and the beam so that in a first position of the beam, the grip elements are located in a position for picking up the strips to be assembled; in a second position, the levers are rotated so that the strips picked up by the elements of each pair of levers are mated at right angles; in a third position, the carriages are mutually adjacent so as to form a frame; and in a fourth position, the corners of the frame are arranged on the stapling machines.
