Abstract:
1. 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 that 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 adjacent the travel path, the sheet of material is nipped by the cam nip to change the travel path of the sheet of material so that the sheet of material comes into frictional contact with a decelerator to selectively decelerate the sheet of material based on an attribute of the sheet of material, wherein the sheet is delivered to one of a first and second hopper depending on a magnitude of the deceleration.
