Specialty Finishing — End of the Line

"What really makes it superior is that the coil is such a good quality, because it has not had time to deform," Spiel points out. "The new breed of automatic coil inserters cannot work with twisted and tangled coil the way a manual machine can. With a manual machine, any kind of coil can go in there because your hand is compensating for all deformities. The new automatic coil machines need fairly straight, uniform coils. This unit provides it because it's being made while you're binding the book."
