IM-306 High Volume Envelope Opener

IM-306 High Volume Envelope Opener

Automatic high speed mail processing

The Model 306, with its ability to operate at a rated speed of up to 40,000 envelopes per hour, sets a new standard for high-volume mail processing. The improved milling cutter with eight cut-depth positions removes chips as small as 0.01” from the envelope edge, producing a soft, feathered edge while protecting valuable envelope contents. Even overnight delivery envelopes are no match for the Model 306. Equipped with a user-friendly interface, job setup is simple and quick.

Backlit LCD control panel

Automatic Mail Opening

High Efficiency

It opens up to 400 envelopes per minute but is ideal for a handful in, a handful out operations. A reverse flow conveyor permits operators to stay in place to both feed and remove envelopes. Auto chaff collection provides a clean workspace while preventing jams and static buildup.

Low Waste

The Series 306 minimises the amount of waste produced throughout the extraction process. Since our milling cutter “chips” away the edge of the envelope, the tiny waste chips are guided into a large capacity chip bin that can be quickly emptied. An ergonomic rolling stand with three mail tray supports and a waste bin are included.

User Friendly

Opens a variety of mixed mail sizes and thicknesses, including flats—easy-to-read backlit LCD with multiple jobs, operator and language settings.

Proven Technology

A precision milling cutter with eight cut-depth positions protects the contents of your mail. Processed envelopes have a soft, feathered edge opening, eliminating paper cuts. The cut depth adjustment knob lets you select from three cut-depth settings, plus a no-cut location for piece counting.
