NORMAL LINERS, CENTRALS AND LACING LINERS
Also called traditional liners , they are tied to the frame by means of screws, though several forms of fixation exist. They can be empty (allen in the liner and coil in the frame), threated (allen in the frame and coil in the liner) or collisioned (to allow a readjustment when these are repaired and lose the original measure). On the upper part, the liners are fixed to the frame by means of tips, which exercise descending pressure, in ad-dition these can be supported on a step in the frame to improve the fixation.
On the wings of the liners, is mechanized the exit, to allow the extraction of the piece after the pressing. In addition these can be made with or without eyelash, which is the element that generates the separation between pieces. If these me-chanizes are made in both faces of the liner, it receives the name of reversible liner, which cannot be supported on the frame and it is used in reversible frames.
