• a first locating wedge located on said one side rail slightly upstream from said first lane divider, said first locating wedge including a generally ramped surface for laterally moving a nested mass of said articles to a predetermined position relative to said first lane divider, a side surface for allowing a first group of articles to move along said one said of said first lane divider, and a plateau area between said ramp surface and said side surface for maintaining said nested mass of articles at said predetermined position;
• wherein said nested mass of articles has a segment line aligned with said first lane divider when said nested mass of articles is at said predetermined position so that a first group of articles in said nested mass moves along one side of said first lane divider and a second group of articles in said nested mass moves along an opposite side of said first lane divider.

An infeed system for separating a nested mass of articles moving in a downstream direction into separate lanes, comprising:

• first and second side rails disposed generally parallel with each other for directing the nested mass of articles in a downstream direction;
• a lane divider positioned intermediate said first and said second side rails, said lane divider including a leading edge constructed and arranged to divide the nested mass of articles into a first group which moves between said first rail and said lane divider, and a second group which moves between said lane divider and said second rail;
• and
• a locating wedge disposed on said first side rail upstream of the leading edge of said lane divider, wherein said locating wedge includes a ramped surface at an upstream end thereof, an elevated side surface downstream of said ramped surface, said elevated surface being substantially parallel to said side rails, said ramped surface and said elevated surface being constructed and arranged to laterally move the nested mass of articles into a predetermined position relative to said lane divider, and a downstream angled side surface tapering from said elevated side surface back toward said first side rail and terminating upstream of said lane divider for allowing said first group of articles to move between said first rail and said lane divider.

A locating wedge for use with a lane divider, the lane divider having a leading edge, to divide a nested mass of articles moving in a downstream direction into a first group of articles and a second group of articles, said locating wedge comprising:
