ABSTRACT:
A pneumatically energized loading mechanism for a drafting device is proposed for loading the upper rolls of the device. This mechanism possesses pneumatic cylinders which subject the upper rolls to a force, which acts from a holder plate (4) for the securement of the cylinder (2). The support is effected by a stop plate (200), which acts in unison with holder plate (4). The cylinder (2) possesses a guide surface (201) positioning the cylinder on the support (4). The cylinder (2) exhibits a piston with a circular cross-section and is comprised of plastic. The cylinder (2) is affixed to the holder (4) by a securement means (20). By the support of the cylinder (2) on the holder (4), the securement means (20) need accept no force engendered by the piston. The cylinder (2) simultaneously forms a passage for a current bus which serves as the power cutoff of the drafting device when fiber windup difficulties arise.
