Abstract
A method and apparatus for processing mail is provided. A feeder serially feeds envelope from a stack of mail. Two cutters at a cutting station cuts one or two edges of the envelopes. As the envelopes travel from the feeder to the cutters the envelope is jogged on two edges to justify the contents with the envelopes. Additionally, an improved feeder is provided to reduce the number of jams created when feeding the envelopes from the stack.
Claims4
A method for feeding envelopes containing contents, comprising the steps of:
- stacking a plurality of envelopes containing contents in an input bin to form a stack of envelopes in which the envelopes are in a generally vertical orientation;
- displacing the stack toward a feeder;
- sensing a pressure of the stack against the feeder;
- driving the feeder to attempt to feed an envelope from the stack;
- detecting whether the feeder fed the envelope from the stack;
- iteratively driving the stack toward and away from the feeder in response to detecting that the feeder did not feed the envelope from the stack.
