KVAL MODEL 777B BI-FOLD HINGE MACHINE |
KVAL's Model 777 Flat Back Bi-Fold Machine is designed to install flat back hinges on bi-fold doors. This machine has a structural frame with four drill stations and three hinge application stations. The basic machine includes set up for 6'8" and 6'6" doors with hinge application units set on fixed centers. The 777 includes spring loaded wheels to support the panels as they are fed through the machine.
Method of operation includes placing a pair of doors in machine and clamping them with a foot switch. Hinges can be placed in machine during cycle operation so they are in position when machine is actuated. Four drills move in to drill for pivot hardware. Hinges are manually placed and screws are automatically dispensed to attach hinges simultaneously. The machine then releases the doors and another operator removes them manually from the off-feed side.
