<p>An apparatus for forming a truss assembly is disclosed which is particularly configured for versatility and efficiency of operation. The apparatus includes a frame which supports a pair of laterally spaced first and second support rails which receive the chords and the webs of the truss assembly being formed. A pair of pressure clamps are provided which are selectively positionable longitudinally of the apparatus frame for applying clamping pressure to nail plate connector portions of the truss assembly for joining the truss webs and chords. Notably, the apparatus includes an arrangement whereby the support rails of the apparatus can be laterally relatively moved for forming truss assemblies of varying finished heights, with the arrangement including a plurality of slide cylinder assemblies which function in the nature of double-acting fluid rams for applying a clamping pressure to this truss assembly laterally of the apparatus frame as the pressure clamps are operated for joining the elements of the truss.</p> |
