Abstract
An apparatus for the threading-in and threading-out of an elastic cover strap in a working cylinder without a piston rod, includes an elongated tubular member (1) having a longitudinal axis; a carriage (21) having a longitudinal axis parallel to the longitudinal axis of the tubular member (1) and mounted on the tubular member for guided movement along the longitudinal axis of the carriage; the tubular member having an elongated recess (7) therein extending along the longitudinal axis of the tubular member, the recess being defined by oppositely facing sides of the tubular member each side having a length defined along the longitudinal axis of the tubular member and a depression (32,33) along the length; an elongated cover strap (8) for covering the recess, the strap having a longitudinal axis, a transverse axis in the plane of the strap, and longitudinal edges sized for mating engagement with the depressions defined in the oppositely facing side walls of the recess (7), and an upper flat surface facing toward the carriage (21) and a lower flat surface facing the recess (7); and a pair of opposed inclined surfaces at the end portions of the carriage extending obliquely to the longitudinal axis of the cover strap and obliquely to the transverse axis of the cover strap in the plane of the cover strap.
