Apparatus is disclosed for flapping envelopes and insert- ing enclosures into the flapped envelopes. The apparatus is con- structed so that parts thereof may be easily moved to substan- tially fully expose the enclosure feed path, as well as the en- velope flap unfolding path and the upstream end of the location at which an envelope is held open and enclosures inserted there- in, thereby facilitating removal of jammed envelopes and en- closures. The components for unfolding the envelope flap are provided as an assembly movably mounted with respect to the en- closure transporter. This allows that entire flap unfolding as- sembly to be moved away from an enclosure transporter, thereby providing access to the enclosure feed path and to the upstream end of a queuing station. The flap unfolding assembly includes two frames which may be pivoted apart to provide access to the flap unfolding path.
