Abstract: A slide cam die including a slide cam base, a wedge-shaped slide cam sliding on a guide surface of the slide cam base and mounting a press tool such as a punch or a trimming blade thereon, and an actuating cam driving the slide cam in contact therewith. A press tool is mounted on the slide cam with an adapter plate interposed therebetween. With this configuration, when a pierce punch, or a flange block, or the like, needs to be removed for reasons such as the adjustment, the pierce punch or the flange block can be individually demounted without removing the entire slide cam. This results in reduced working time. In addition, since only the adapter plate is replaced, cost savings can be achieved by reusing the slide cam. Furthermore, a given slide cam can be used while still maintaining flexibility in design and use of the slide cam die.

Abstract: A cutoff system for exterior siding which includes a flying punch and shear. The system includes a main carriage which is adapted to reciprocate and, in one direction of travel, move at the same speed as the siding to be cut. A pair of punches are then actuated to form the hanger and butt notches at the lateral edges of the siding. Upon withdrawal of the punches, the travel of the main cylinder is slowed such that the siding travels away from the punching area. Upon sensing the notched areas, the main carriage is again moved to travel at the same speed as the siding. The speed is timed such that the center of the notches is located below a shear. This shear is then actuated to form a single parting line across the siding. The carriage is then retracted to await the next cycle of the system. As such, with each cycle of the system, the notches are formed in the trailing and leading edges of adjacent panel segments, and the leading panel segment cut from the continuous siding.

Abstract: A spring return mechanism for returning the movable blade and connected slide plate to their at rest position in a flying shear. The device is positioned outboard of the movable and fixed blades, each of which has mating and alignable apertures through which long lengths of stock material to be sheared into shorter segments are continuously fed. Each device includes an upright elongated spring housing, a compression spring acting within the housing, and a guide button which moves up and down within the housing to return the slide plate and connected movable blade back to their at rest position immediately after each shearing. The guide button has an upper end which allows the slide plate to move or slide diagonally downward against the guide buttons following the diagonal motion of the movable blade during each cutting cycle.

Abstract: A roll forming apparatus disclosed has a series of roll forming stations with a first group of stations having rollers that are adjustable to different width settings using the same rollers to form more than one width of ogee type gutter. A cutter uses interchangeable cutting blades and die plates for shearing different gutter sizes to selected lengths.
