ABSTRACT:
A cutting installation for a fabric web comprising an unwinding unit, a downstream dancer unit serving as a buffer, and a downstream cutting frame with a cutting unit disposed thereon. At least two gripper beams extending parallel to the cutting unit and guided along a lateral rail arrangement are displaceable across the longitudinal extension of the cutting frame, and each gripper beam on one side is carried by a first support tower which is displaceable along the rails, and on its opposite end is provided with a telescopically extendable extension piece. The extension piece can be docked with a second support tower arranged on the opposite side and traveling along. The support towers are adapted for adjusting the height of the respectively carried gripper beam, such that each gripper beam, as it moves along the cutting frame, can travel over the other gripper beam.
