Abstract
A full rotation type, sheet web shearing machine comprising a rotary blade with a shearing edge, a stationary blade with a shearing edge, a motor for driving and braking the rotary blade, a cam for detecting a rotation angle of the rotary blade and gears for reducing the revolution speed of the motor. The full rotation type, sheet web shearing machine may cut sheet web to a given length. Owing to one full rotation of the rotary blade, it can cut the sheet web running continuously at a high speed without jam. The rotary blade is rotated, through gears driven by the motor and also is braked by making a braking circuit between electrical terminals of the motor so that the rotary blade is stopped at a predetermined angle.
