Inserter and method for opening an envelope throat of an envelope transported along an envelope channel

A method for opening an envelope throat of an envelope transported along an envelope channel while the envelope is being transported along the envelope channel comprising at least one of the following steps (i) and (ii):

• (i) moving the envelope past a counter-guide that is displaced in an identical direction as the envelope channel with reference to the envelope and past an over-presser that is displaced in the identical direction as the envelope channel with reference to the envelope;
• and
• (ii) moving the envelope past an over-presser that is displaced in an identical direction as the envelope channel with reference to the envelope, acting counter to a hold-down force that holds the envelope down on an envelope transport.

An insider for inserting at least one item into an envelope that moves along an envelope channel, said inserter comprising an opener for opening a moving envelope and holding the moving envelope open, wherein the opener comprises at least one over-presser that is fixed in place and a counter-guide that is fixed in place and acts against the at least one over-presser.

An inserter for inserting at least one item into an envelope that moves along an envelope channel, said inserter comprising an opener for opening a moving envelope and holding the moving envelope open, wherein the opener comprises a distortion of a selected cross-section of the envelope channel selected perpendicular to a movement path of the envelope through the envelope channel.

An inserter for inserting at least one item into an envelope that moves along an envelope channel, said inserter comprising an opener for opening a moving envelope and holding the moving envelope open, wherein the opener comprises a convex curvature of the envelope channel with reference to the envelope in a movement direction of the envelope.
