ABSTRACT:
A safety system for the drive of a cross cutter for a web of material, having an electrical or mechanical synchronizing system between the drives of the feed and cutting mechanism which is adjustable for the size of the piece to be cut and which consists of an adjustable asymmetrical mechanism and has speed control associated with the drive of the feed mechanism to limit the speed of the feed means on the basis of a signal corresponding to the setting of the asymmetrical mechanism. A function generator generates a signal to be applied to the speed control which is directly dependent thereon to define the speed value for the drive of the feed mechanism and wherein the function generator is responsive to the asymmetrical mechanism for size-related, maximum permissible web velocity.
