## Abstract

A unique and simple method of picking and feeding of envelopes is described and illustrated above. With this method, the envelope (A) is picked with a counterclockwise or upwards rotating picker roller (B). The surface in contact with the envelope (A) is a material with a high coefficient of friction (40-45 shore) causes the envelope to travel upward. When approximately one to two millimeters from the floor, a positive drive surface (D) comes in contact with the bottom of the envelope. This prevents double feeds as the roller (B) cams the second envelope back away from the picker roller. The surface of the picker roller (E) at this point has a very low coefficient of friction; thus, slipping easily on the surface of the second envelope.

Envelope Pick And Feed Device

A unique and simple method of picking and feeding of envelopes is described and illustrated above. With this method, the envelope (A) is picked with a counterclockwise or upwards rotating picker roller (B). The surface in contact with the envelope (A) is a material with a high coefficient of friction (40-45 shore) causes the envelope to travel upward. When approximately one to two millimeters from the floor, a positive drive surface (D) comes in contact with the bottom of the envelope. This prevents double feeds as the roller (B) cams the second envelope back away from the picker roller. The surface of the picker roller (E) at this point has a very low coefficient of friction; thus, slipping easily on the surface of the second envelope. Envelope #1 follows the rotation of the picker roller (E) around until it meets the contact point of drive roller (F) which sends the envelope to the feed rollers (G) and (H) which sends the envelope into the paper path for the print cycle; thus, completing the pick cycle.
