Abstract
A flexible leaf causes the gummed flap of an envelope to enter a chamber in which a moistening element is exposed. In addition, a pivoted and spring-biased element yields upon engagement of the envelope spine therewith. Further movement of the envelope wipes the flap across the moistening element, and the spring-biased element presses the moistened flap against the body of the envelope.
