Document guide apparatus for preventing jams

DETAILED DESCRIPTION There is disclosed an envelope inserting machine having an elongated feed deck, with an apparatus for advancing insert material along the feed deck.
There is a plurality of insert material feeding devices spaced along the feed deck for sequentially feeding insert material onto the feed deck in registration with insert material advancing along the feed deck to registration devices.
There is a plurality of support members connected to the feed deck which extend laterally outwards from the feed deck.
There is provided a plurality of body members, each having a first portion overlying the feed deck and which extend parallel thereto, and a second portion extending laterally outwardly from the first portion and overlying the support members.
There is a registration guide apparatus mounted on the first portion of each of the body members for guiding the insert material into registration with other insert material on the feed deck.
The guide apparatus has a generally upright and L-shaped configuration which defines a closed unitary corner along which the lateral edge of the insert material moves.
There is an apparatus for slidably clamping the second portion of each of the body members to the support member underlying the second portion of each of the body members in a desired lateral position with respect to the feed deck to force each of the guide apparatus mounted on the first portion of each of the body members into intimate contact with the feed deck whereby the guide apparatus forms a continuous horizontal support for said insert material to prevent the lateral edges of the insert material from being caught between the upper surface of the feed deck and the registration guide.
The insert material registration devices with the first portion of each of the body members includes an elongate upstanding flange extending generally parallel to the feed deck.
The registration guide apparatus includes an upstanding generally U-shaped portion which fits over the upstanding flange of the body member and a unitary horizontal flange overlying the feed deck, the U-shaped portion and the horizontal flange forming the closed unitary corner
