ABSTRACT:
An apparatus for applying latex sealing material to the facing closure flap and opposed body portion of an envelope includes a continuous belt driven conveying means having a generally triangular path, with the envelopes being fed onto the conveying means at one point in the triangle, with the conveying means gripping each of a series of envelopes along its folded edge portion opposite the flap. As the envelopes are conveyed, the flap is first unfolded through an angle of approximately 180.degree. to a generally horizontal position, after which the envelope is passed between an impression roller and a latex applicator roller at which latex is applied to the facing closure flap and the body portion of the envelope. The impression roller and glue roller are disposed at the second point of the triangular path of the conveying means, and next the envelopes are passed through a dielectric dryer for drying the latex sealing material. Upon leaving the dielectric dryer, the path of the conveyor means passes through the third point of the triangle, and progresses back toward the original starting point. At the latter point, means are provided for removing the envelopes from the conveyor means. By this arrangement, a single operator may readily feed and unload the apparatus of the subject invention. In the method for applying strips of latex 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 latex 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 dielectric dryer means to dry the latex material. Finally, the envelopes are removed from the conveying means and stacked.
