A high-speed envelope transport and insertion machine includes a slip-drive system having a plurality of belts configured to move envelopes along an envelope path at a first speed, an envelope transmission device disposed to input envelopes into the slip-drive system, an envelope stuffing device comprising a registration member and a drive member having a plurality of spaced-apart gripping members disposed to move continously between the slip-drive system and the envelope stuffing device at a second speed less than the first speed. The path of the gripping members and the envelopes crosses within the slip-drive system to permit the gripping member to engage and grip the envelope. The gripping member is configured to release the envelope upon registration of the envelope against the registration member of the envelope stuffing device.
