Method for making high precision spring elements for clocks and timers etc involves supplying flat foil material of required end thickness to roller cutter to divide foil into several individual strips of desired width

摘要

The method involves supplying a flat foil material (6) which has the required end thickness of the spring elements to a cutter (1) to divide the foil into several individual strips (7) which correspond in width to the desired end width of the spring elements. The individual strips obtained are stored interim on spools (8) prior to further processing. Independent claim describes device for carrying out method using a roller cutter machine (1) with two opposite positively interengaging sets of rollers (2, 3) and guides (4, 5) extending from the input to the output side of the cutter machine.
