    Abstract: There is provided a method and apparatus for the attachment of clasps on letter envelopes incorporated into a machine for the manufacture of letter envelopes. The clasps, at the conclusion of the folding operation of the envelope machine, following the folding down of the lateral flaps of the envelope, are attached to the newly formed back sides of the letter envelopes. The apparatus is arranged for this purpose at the downstream end of a lateral folding mechanism of the envelope machine and includes a stationary opposing support plate.

    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.

    Abstract: An approved method and apparatus for forming clasp envelopes. The apertures extending through the top and bottom panels of the envelope body and the clasp receiving aperture extending through the top flap are formed after the envelope has been completely assembled save for the folding of the top flap for shipping. This ensures that the apertures extending through the top and bottom panels of the envelope body are in perfect registration. Reinforcement tape is applied on the top flap of the envelope, through which the aperture in the top flap extends, after the envelopes have been cut from the continuous strip of envelope blanks. This ensures that the cutting device used to sever the continuous strip into individual envelopes must cut only paper, thus improving longevity of the cutting device, and allows a single punch device to be used to form the hole and the apertures. Additionally, the method and apparatus employ an improved device for applying the clasp to the back panel of the envelope body. This clasp attaching device includes a resilient anvil which is adjustable to vary the prong insertion depth and is completely removable to allow test runs without the application of the clasps.
