This unit is a 3M 12AF Automatic Unform flap closing case taper/carton sealer/carton taper.
The unit is complete and in very good, operational condition. Has top and bottom 3M tape heads.
This style of taper can be put "in-line" and accept cases or carton that require the top to be closed and taped. It will automatically close all major and minor flaps and apply tape to the top (and bottom if required) of the box.
Requires 115V AC power and compressed air.
