ABSTRACT:
An apparatus for slitting a web moving along a path in a transport direction has a support transversely shiftable relative to the web adjacent the path, a drive shaft extending transversely of the direction adjacent the path and substantially nonmovable transversely of the path, and a drive gear on the support rotationally coupled gear to the drive shaft and shiftable along the shaft. A mount shiftable toward and away from the shaft on the support carries at least one driven gear and a driven blade fixed to and rotatable with the driven gear. Another blade is juxtaposed with the driven blade and flanks the path therewith. An actuator can shift the mount between a cutting position with the blades closely juxtaposed and the driven gear meshing with the drive gear and a retracted position with the blades separated and the driven gear out of mesh with the drive gear.
