Abstract
A beltless automatic feed chadless envelope slitter device is disclosed. A separator-alignment assembly assures that only the lowermost envelope received from an infeed zone is passed downstream to a slitter and the envelope so-passed has its marginal edge aligned with a guide fence. The separator-alignment assembly is comprised of a pair of drive wheels having upper peripheral portions projecting above the table in combination with a pair of drag levers having high friction portions at the lowermost ends thereof. The high friction portions are preferably spring urged toward the table, and are shiftable upwardly and downwardly to accommodate envelopes of varying thickness and envelopes which themselves include varying thickness portions. The high friction components are urged toward the table at positions laterally offset from the peripheries of the drive wheels. Preferably, the drive wheels rotate about an axis inclined to define an included angle in a downstream direction with a guide fence of less than 90 degrees whereby the conjoint action of the drag means and peripheral portions urges the envelope passing over the peripheral portions in a direction laterally toward the guide fence. Optionally, the slitter may incorporate a modular precision slitting element whereby the entire slitter components may be interchanged.
