Abstract
Abstract Equipment is provided for machine forming, e.g., cutting off, punching, and the like, extruded siding formed of resin materials. A plurality of punch blades are mounted in a linear series for punching nail holes in the hanger edge of the siding, and a cut off knife and notching punches are mounted on a carriage and provide for cut off of lengths of the siding and for notching out portions of the hanger and butt edges, to facilitate overlapping of the siding upon installation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
224 words
Apparatus for use in machine forming extruded resin siding having hanger and butt edges with an intervening panel, comprising mechanism for punching spaced nail holes in the hanger edge including means for guiding the extruded siding endwise through a predetermined feed path, a plurality of punch blades mounted in a linear series at one side of the feed path, die mechanism at the opposite side of the feed path and having a linear series of die openings for cooperating respectively with the several punch blades, means for periodically actuating the punch blades as the siding advances through the feed path, a first carriage for mounting said punch and die mechanism, said first carriage being mounted for motion in the direction of feed of the siding through said feed path during the punching operation, mechanism for cutting off siding pieces of predetermined length located downstream from said punch and die mechanism, said cutting off mechanism including means for guiding the extruded siding endwise through a predetermined feed path and a cut off knife, said cutting off mechanism being mounted on a second carriage movable independently of said first carriage and mounted for motion in the direction of feed of the siding through said feed path during the cut off operation, and means for periodically actuating the knife as the siding advances through the feed path.

Claim 4
Dependent Claim
39 words
Apparatus as defined in claim 1 and further including a metering wheel running in engagement with the siding as it advances through its feed path and control mechanism operated by the metering wheel to periodically actuate the punch blades.
Claim 5
Dependent Claim
35 words
Apparatus as defined in claim 1 and further including a punch mounted on said first carriage for punching a weep hole in the butt edge of the siding when the nail hole punches are actuated.
Claim 6
Dependent Claim
22 words
Apparatus as defined in claim 1 further including power means for advancing the first carriage with the siding during the punching operation.
Claim 7
Dependent Claim
62 words
Apparatus as defined in claim 1 and further including, a notching punch mounted on said second carriage for removing a portion of the hanger edge of the siding, clamping means mounted on the second carriage for holding the siding during the cut off and notching operations, and means for periodically actuating the notching punch as the siding advances through the feed path.
Claim 8
Dependent Claim
23 words
Apparatus as defined in claim 6 in which the clamping means includes clamps located both upstream and downstream of the cut off knife.
Claim 9
Dependent Claim
168 words
Apparatus for use in maching forming extruded resin siding having hanger and butt edges with an intervening panel, comprising mechanism for cutting off siding pieces of predetermined length and for notching out portions of the hanger and butt edges at one end of the siding pieces, said mechanism including means for guiding the extruded siding endwise through a predetermined feed path, a cut off knife, a notching punch for removing a portion of the hanger edge of the siding, common mounting means for said knife and said punch, a notching punch mounted independently of the cut off knife for notching out a portion of the butt edge of the siding pieces, a common carriage for the cut off knife and both of the notching punches, and means for periodically actuating the knife and notChing punches as the siding advances through the feed path, the carriage being mounted for motion in the direction of feed of the siding through said feed path during the cut off and notching operations.
