3.1 Feed Mechanism
An exclusive feed design mechanism feeds many different size envelopes with-
out pre-sorting and is virtually jam proof.
* Note the twin spiral feed belts (M, see Fig. 1). Their spiral counterclockwise action
shunts envelopes against the back plate for precision slitting. Note that the belt at left
is angled more sharply. This "pre-feeds" envelopes to the belt at right.
* The transporter wheel (not shown), another Model 62001 feature, acts as a further
assurance that out-size pieces will be shuttled inward on the front deck (Fig. 2).
* The holdback wheel (C) prevents jamming at the loading end. Since it is spring
loaded, the bulkier the envelope, the greater the pressure exerted by the holdback
wheel. This effectively prevents entry of more than one piece of mail at a time.
The combined action of these interrelated parts eliminates many of the problems
associated with conventional mail opening machines and explains why the Model 62001
can deliver a high speed capacity of 17,500 mixed envelopes per hour.
3.2 Ski Assembly
The ski assembly (D) guides envelopes straight into the blade assembly (E).
Front and back adjustments are factory set to apply correct pressure to letters of vary-
ing size. (NOTE: Should adjustment become necessary, loosen the locking nut and
adjust the black thumbscrew accordingly. Retighten the locking nut).
3.3 Blade Assembly
Self-sharpening blades made of precision steel (E) cut a measured strip from
each envelope, whether fed face-up or face-down. The control knob at right (see Fig. 2)
adjusts the blade and permits the operator to vary the width of cut from wide to fine.
3.4 Ejection Assembly
The ejector wheel (L) pulls the envelopes out into the catcher base (I). The pres-
sure plate directly above it (K) keeps the envelope in position for accurate ejection. The
plate deflector (G) angles pieces downward into the catcher base.
3.5 Catcher Base
The catcher base (I) receives all opened envelopes as they leave the blade and
ejection assemblies. A separate light-weight scrap bin (H) keeps scrap separate from
opened envelopes for easier disposal.
3.6 Split Deck
Interiors of most mail opening machines are inaccessible without the removal of
the entire operating assembly. The Model 62001 has a unique split deck feature which
solves that problem. The deck is split lengthwise into two halves, front (see Fig. 2) and
rear. The front half is removable, making cleaning, inspection and repair of the interior
of the letter opener easier.
