Abstract
A paper web slitter having upper and lower slitter heads supporting cooperating rotary slitter blades, and wherein the lower slitter heads and blades together with appurtenances are of such narrow profile that the paper web is adapted to be separated into unusually narrow strips. In particular, the lower slitter heads carry motors which have driving connection on driving axes normal to lower slitter blade spindles supported in stable bearings in journal boxes on the generally triangular narrow profile standards on the lower slitter heads.
