This retractable central conveyor (1) being used in a folder-gluer converting plate-like workpieces such as paper or cardboard for producing packagings. Such a folder-gluey comprises two frames between which are arranged two lateral conveyors (100, 110), the conveying means of which being belts (101, 111). The conveyor of the present invention comprises a structure consisting of four associated components (4, 5, 8, 11) which are transversely movable between the frames of the folder-gluer with respect to the travelling direction of said plate-like workpieces. Among these components of this structure, an upper longitudinal bar (4) can easily be manually lowered, in a vertical slanted movement, from a working position to a retracted position, and inversely raised by independent damping means (15). The central conveyor (1 ) can be retracted between the two lateral conveyors (100, 110) thus enabling the folder-gluer to be used in a new configuration where uncoupling of the transmission means necessary for the independent drive of the belt (30) is not required and which belt (30) is rotatable even in the retracted position. This conveyor allows to arrange the two lateral conveyors (100, 110) side by side so that the useable conveying width of the folder-gluer is reduced to a minimum value.
