ABSTRACT:
Web severance is effected between non-contacting radially opposed severance points of circular edges on rotary upper and lower members between which continuously running paper web to be slit is engaged, the space between the severance points being sufficiently less than the thickness of the paper web and so related to the physical properties of the web as to cause severance of the web as a result of web fiber failure separation fracture at the point of maximum compression.
