Abstract
A web processing roll for handling a web of material using vacuum is provided. The web processing roll includes a roll body. The roll body defines an outer periphery against which the web of material is held. The roll body defines a vacuum passage. At least one first vacuum hole fluidly connects to the vacuum passage provides vacuum proximate the outer periphery of the roll body to hold the web of material against the outer periphery with vacuum supplied to the at least one first vacuum hole by the vacuum passage. A first flow path of the vacuum hole extends at a first angle that is non-perpendicular to the rotational axis and is directed, at least in part, axially toward one of the first and second ends at the first outlet end of the at least one first vacuum hole.
