Patent ID: 8505908

Claim:
A method for decelerating a sheet of material traveling along a travel path at a first speed, the method comprising: delivering the sheet of material past a cam nip comprising at least one lobe end, the cam nip being rotatable on a first axis substantially perpendicular to the travel path; and driving rotation of the cam nip, such when the at least one lobe end of the cam nip is away from the travel path, the sheet of material can pass substantially unimpeded past the cam nip, and when the at least one lobe end is near the travel path, the sheet of material is nipped by the cam nip decelerating the sheet of material from the first speed to a second speed; wherein the at least one lobe end comprises a rotatable wheel; wherein said cam nip comprises at least two lobe ends and each lobe end comprises a rotatable wheel.
