Abstract

Longitudinal slitting machine having associated upper and lower knives. Knife holders for the upper knives are supported on a crosspiece. A knife head is carried by a lowering mechanism and supports an upper knife in the form of a circular knife, the lowering mechanism including a piston having a piston rod for the knife head. A path of movement of the circular knife into a cutting position is delimited by an abutment, and a depth adjuster fixes the cutting position when the knife head is lowered. A setting instrument indicates the position of cutting edges of the upper knife relative to the lower knife with reference to the true diameter of a new circular knife. The depth adjuster is positioned in conformity with a position value determined by the setting instrument. A sensor is aligned with an outer periphery of the upper knife, and during alignment of the sensor with the cutting edges of the upper knife, which alignment is effected by positioning of the depth adjuster and/or displacement of the sensor, an adjusting mechanism for a movement of the circular knife into its cutting position is fixed.
