Abstract: An apparatus of feeding mailpieces such as envelopes is disclosed. The apparatus includes a supply conveyer for supporting thereon an array of mailpieces which are arranged in a tilted-backward position and moving such mailpieces forward, and a suction feeder which is located downstream of the supply conveyer for picking up by suction a forefront mailpiece from the array of mailpieces on the supply conveyer. The suction feeder has a rotary drum, a shaft rotatably supported in the drum and disposed with the axis thereof oriented in parallel to and offset from the axis of the drum. An external gear is fixed on the shaft for rotation therewith and a stationary internal gear engages with the external gear, the gear ratio of the external gear to the internal gear being n:n+1, wherein n represents an integer.
Abstract: A method and an apparatus of inserting insert or enclosure material into successive envelopes are disclosed. According to the envelope inserting method, the insert material is conveyed along a straight path successively to an envelope inserting position where the insert material is inserted into the envelope and the stuffed envelope is then conveyed out of the inserting position in the same direction as the above straight path. The method includes providing immediately above the envelope inserting position an envelope storage station where a plurality of envelopes are stored in a stack one above another with the front panel of each of the envelopes facing upward so that the envelopes in the storage station are fed successively to the envelope inserting position for insertion thereinto of insert material.
