<p>A method of operating a side trim or slitting shear to shear a full length of a material (10) to be sheared is described. The full length comprises a plurality of cutting lengths and the shear comprises a first blade (6) and a second blade (7). The methodcomprises determining parameters of a material to be sheared and storing the determined parameters. In one cutting cycle, the method comprises cutting a single cutting length (14) of the material; carrying out a series of cutting cycles to cut the full length of the material; and in a control system at least once in the series of cutting cycles using the determined parameters to control adjustment of the gap (H) between the first and second blades in a cutting phase in a cutting cycle. The angle between the blades may also be adjusted </p> |
