Linear guide means

A linear guide unit comprising a guide rail with an axis and a guide rail profile and at least one guide carriage guided on the guide rail in the direction of its axis, wherein at least two rail treating units are disposed on the guide carriage and are adapted for movement in a plane substantially at right-angles to the axis and are pre-tensioned toward the guide rail so that each of them has a contact edge resting on a part of the periphery of the guide rail profile, the contact edges of the at least two rail treating units mutually overlapping in the peripheral direction of the guide rail profile.

A linear guide unit comprising a guide rail with an axis and at least one track and at least one guide carriage with at least one running element which in an operating condition is guided on this track, whereby there is mounted on the guide carriage a treating unit carrier for at least one rail treating unit, said rail treating unit being guided on the treating unit carrier in a plane substantially orthogonal to the axis by guide means and being pre-tensioned toward the guide rail, said rail treating unit being captively disposed in the treating unit carrier, said treating unit carrier being preassembled and comprising two carrier parts which bear on each other like a sandwich;

• said guide means being disposed in the region of contact surfaces of the sandwiched carrier parts, said at least one rail treating unit and pre-tensioning means associated thereto being after insertion in partial guide means of one carrier part secured against separation from the treating unit carrier by juxtaposition of the contact surfaces of both carrier parts and by fixing the two carrier parts to each other.

A pre-assembled treating assembly adapted for being mounted on a guide carriage of a linear guide unit, said linear guide unit comprising a guide rail with an axis and at least one guide carriage guided on the guide rail, said pre-assembled treating assembly comprising a treating unit carrier, at least one rail treating unit guided on this treating unit carrier and pre-tensioning means for pre-tensioning the rail treating unit toward the guide rail, said pre-assembled treating assembly further comprising releasable means which maintain the rail treating unit in an inoperative position against the action of the pre-tensioning means.
