An apparatus for applying latex areas to the seal flaps of paper envelopes and drying the latex is adapted to be placed either "in-line" or "off-line" with respect to a die-cut high speed envelope manufacturing machine. The apparatus includes a rotatable electrically insulated drum which acts as the ground for a radio frequency dryer (dielectric dryer) whose positive electrodes are adjustably spaced from the drum surface. The envelopes, during application of the latex and its drying, are held between flexible belts having projecting guides and are conveyed, still between the belts, by the rotating drum beneath the electrodes, with the latex exposed to the radio frequency drying.

Gum applying apparatus including a pair of gum applying dies mounted on a common shaft for applying gum along and adjacent to the side edges of an envelope blank during the manufacture of the blank into an envelope. Each of the dies includes a central circular plate and a pair of circular sectors spaced from each other about the circumference of the circular plate. The sectors are in contact with a gummer roll which transfers gum from a container to the sectors. The gum is applied by the sectors to spaced envelope blanks on a conveyor belt beneath the sectors. The space between the sectors is adjacent the conveyor when the space between the blanks on the conveyor traverses the gum applying station thereby precluding gum from being applied to the belt running through the station; but enabling the gum to be applied continually to the envelope blanks. Means are also disclosed to control the amount of gum transferred to the gum applying die sectors.

An envelope is provided with a first and second button having a depending portion inserted through an opening in a flap and an adjacent body portion, respectively, which is then flattened by the application of ultrasonic energy to vibrate each button and its depending portion against an anvil, rendering each button captive on the envelope. A string is inserted through a slot or hole in the depending portion of one of the buttons and fused to the button as the depending portion is flattened. The string is used to releasably connect the buttons and thus, the envelope flap to the adjacent body portion.

Apparatus for applying gum to spaced portions of an envelope is provided with means for sensing the absence of an envelope on a conveyor belt feeding the envelopes to the gummer apparatus. In response to sensing the absence of an envelope on the conveyor belt, a gummer cylinder containing spaced gummer pads for applying gum to the flap and body of the envelope is precluded from rotating by disengagement of a clutch between the gummer cylinder and its drive and simultaneous contact of a brake with the cylinder.

An RF dielectric heater has a variable power output and stable output frequency. A power controller provides variable phase angle control of three-phase AC power. A delta-wye power transformer is coupled between the power controller and a rectifier circuit. The rectifier circuit converts the stepped up, high voltage AC power from the transformer into a DC power output. An RF oscillator circuit driven by the DC power output is coupled to a tank circuit. A load, comprising RF electrodes, create an RF field to heat material passed through the field. The RF electrodes are coupled to the tank circuit in a manner characterized by the absence of any tuning components.
