Abstract
A device is disclosed for limiting the movements of a shaft in response to the changes in tension in a sheet passing in contact with the shaft, and a cutting machine using such a device. The device comprises at least one cylindrically shaped member (10, 11) designed to be placed in contact with the said shaft (16) so as to limit the movements, each of the cylindrical members (10, 11) allowing two levels of contact with the shaft, a first variable level on a non-metallic surface of the member for normal tension conditions in the sheet (17) and a second, substantially fixed level for abnormally high conditions of tension in the sheet.
