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. The cutter uses a rotary drive member to move the blade in a path having a relatively short stroke that performs a scissor-like cutting action to successively cut the walls of the formed gutters for each revolution of the rotary drive member. A crank member for manually moving the cutter blade is collapsible and the crank handle is demountable for transport purposes.
