ABSTRACT OF THE DISCLOSURE An improved cutting device of the type having rotary vane knives, which cooperate with stationary knives, for making patterned cuts in the edges of paper webs, particularly for the preparation of envelopes or envelopeblanks, is provided. The device includes at least one cooperating knife pair, comprising one rotary knife and one stationary knife, disposed for cooperative engagement for making patterned cuts in the edges of paper webs moving therepast. The blades are made of materials differing from one another in hardness to an extent such that the softer knife can have material re- moved from it without damage to the latter, and at least one of the knives of the cooperating knife pair, is mounted for feeding movement toward its associated co- operating knife, while the cutting device is operated.
