An apparatus and method is provided for applying sealing material to the facing closure flap and opposed body portion of an envelope, the apparatus including a continuous belt driven conveying means for conveying envelopes with closed flaps to a sealing material applicator after unfolding the closed flaps through an angle of approximately 180.degree. to a generally horizontal position, after which the envelopes are passed through a dryer for drying the sealing material, subsequent to which the envelopes are removed from the conveyor means and in consequence of which a single operator may readily feed and unload the apparatus of the subject invention. In the method for applying strips sealing material to the envelope, the envelopes are fed to the conveying means, the flap closures are sequentially rotated to a generally horizontal position in order to next enable the application of sealing material to both the inside surface of the flap closure and the opposed body portion of the envelope, after which, the envelopes are passed through a drier to dry the sealing material; finally, the envelopes are removed from the conveying means and stacked. |
