This is an Auto Tong-Feed System equipped with automatically-operating mechanical tongs. An ATF machine will take the place of two to four hand feed machines on the same job. Featuring fully automatic feeding and transferring through the dies, these high-output, labor-saving forging machines fit ideally into the modern automation concept.

Heated blanks are delivered to the machine magazine and then injected into the various die stations. As the heading ram recedes on each stroke, mechanical tongs carry the forging blanks downward from die to die until a finished forging drops from the machine.
