Abstract
A strip mill entry guide mechanism having upper and lower platens positioned to receive and clamp strip material passing therebetween. One of the platens is driven by a first drive mechanism toward the other platen into clamping engagement with the strip. This first drive mechanism is locked in this clamping position to prevent its forced retraction therefrom while this same driven platen is further driven into heavier clamping engagement with the moving strip with a second drive mechanism disposed between the locked first said drive mechanism and the platen being driven.
