Abstract:
A method of producing a floor-bridging unit, the floor-bridging unit including a X member of two legs, two flanges attached to sides of the X member and where a distance A between the flanges is a desired distance which sets the size of the floor-bridging unit, the method comprising:cutting legs to a desired length, the desired length of each leg being long enough to produce the X member having the distance A between the flanges; indexing one end of each leg, such that the same end of each leg is indexed in relation to the cutting of the legs for assembly of the floor-bridging unit; cutting a dado slot near the middle of each leg to remove material in each leg, the dado slot being a set distance from the indexed end of each leg; assembling the X member by assembling two legs together at the dado slot of each leg to form the X member, such that the indexed end of each leg is on the same side of the X member; trimming the sides of the assembled X member which receive the flanges, such that the distance between the sides are the distance A; applying glue to the sides of the assembled X member which receive the flanges; placing the X member in a nailing station of a plurality of nail guns; positioning the flanges against the sides of the X member; and nailing the flanges to the sides of the X member.
