ABSTRACT:
An envelope opener device is provided characterized in that the envelope, which is automatically fed, is slit through only a single face of the envelope whereby no portion of the envelope is severed entirely, thus minimizing the possibility of loss of the contents. A further characterizing feature resides in a unique device for adjusting the cutting depth to achieve a precisely desired cutting effect, the depth adjustment means being actuatable for the slitting of envelopes of thinner stock, such as air mail envelopes. The device is resistant to feeding an envelope which is so disposed that the envelope contents are in registry with the cutting mechanism, thereby minimizing the possability of damaging the contents.
