Abstract:
An apparatus for manufacturing rectangular frames composed of strips which are assembled by way of mutual joining elements which are driven into said strips by stapling machines so as to straddle joints formed by mating said strips at right angles, comprising: 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 said vertical axis, each arm of said two arms being provided with sliding guides for respective carriages; two levers, which are articulated to each one of said carriages about axes which are parallel to said vertical axis; a grip element for a respective one of said strips that constitute said frame being mounted on each one of said levers; means for actuating said grip elements, said levers, said carriages and said beam so that in a first position of said beam, said grip elements are located in a position for picking up the strips to be assembled; in a second position, said 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, said carriages are mutually adjacent so as to form a frame; and in a fourth position, the corners of said frame are arranged on said stapling machines.
