<p>With reference to Figure 3, a method of manufacturing video casette leaf springs comprising the steps of: a) feeding stainless steel strip material (10) of width substantially corresponding to the intended length of the springs (1) in the direction (13) of the longitudinal axis (12) of the strip (10), b) forming slots (14) in the strip (10) which extend inwardly towards each other from the edges of the strip and along lateral axes (15) disposed substantially normal to said longitudinal axis (12), and c) cropping the strip along said lateral axes (15). Spring locating holes (4) are preferably formed in the strip (10) and the ends of strip material (10) between the slots (14) may be cropped so that they become rounded. The strip material is deformed (5) so as to strengthen the springs.</p> |
