990-F4 Line 2014

KVAL’s 990-F4 is the perfect marriage of our high-speed pre-hanging line with the additional flexibility to machine 6’8” doors for three hinges and 8’0” doors with four hinges. Changeover from one door height to the other takes only a couple of minutes and requires no tools. For even greater flexibility this 990-F4 is equipped with the Six-Shooter to install 3-1/2” x 3-1/2” hinges. This line includes a Handler Door Feeder and 700-C Assembly Machine.

Operating the 700-C includes placing the strike jamb and header into the machine and clamping into place. The door, with hinge jamb installed, is then moved into position, gently lowered into place, and then securely clamped into position. Two-Hand control Palm Buttons activate the clamping sequence and vertically move staple guns into position to attach the jambs to the header. Activating staple gun “fire” sequence is initiated with one palm button and the “fire guns” push-button on the control panel on machine. The door is then raised and rolled out of the machine to the next station to the packaging station.

The Handler Door Feeder automatically feeds doors from a 65” high stack onto a powered roll table with cross transfer belts to align the door to a rigid fence for feeding to the next machine in the line. The Handler will feed 1-3/8” or 1-3/4” doors that are a maximum of 3’6” x 8’0” weighing up to 150 pounds. Flush, molded, or stile & rail door can be fed using the Handler. The door is clamped on the top and bottom, lifted, and laterally transported over the feed table. The door is then lowered onto the powered roll table, which will move it to the next machine in the line when the “clear to feed” signal is received. All door contact points are padded to avoid any damage to doors. Conical set screws are used on the top and bottom edge of the door for a positive grip.
