Abstract: A low profile linear movement lock-up system that uses a rack-and-pinion gear mechanism to open and close a sliding jaw to selectively tighten and loosen a print carrier sheet on a print roll. The rack-and-pinion gear mechanism includes a sliding cam with diagonal cam slots and locking clip with pins that slide within the cam slots to open and close the jaw. The rack-and-pinion lock-up device may be configured for installation on a print roll, either in a new machine or in a retrofit application. The rack-and-pinion lock-up device may also be deployed within a print roll, or as a printing machine including a print roll with a rack-and-pinion lock-up device. An existing printing machine may be retrofitted by replacing its existing lock-up system with the rack-and-pinion lock-up system.
