    Abstract: 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.

    Abstract: 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.
