ABSTRACT:
To form a protective cover for an elongated machine element, such as a feed spindle or the like (1), a tubular structure (7) which may be formed of a plurality of parallel strips (7a) has edges which are formed with an interengaging, interlocking but separable ridge or rib-groove construction (10, 9) similar to a slide fastener. To provide for secure interengagement and covering of a traveling element (2-4) on the spindle, a guide cone (16) is secured to the traveling element surrounding the tubular structure. The guide cone may include a hub (4) formed with a part-circumferential opening or openings (15) through which the opened guide tube portions can pass to permit the traveling element to move while providing continuous protection to the spindle upon movement thereof, the guide cone insuring reclosing of the rib-and-groove behind the movable element, and opening in advance thereof. The tube may be formed, in addition, with longitudinal guide grooves (23) in which closing elements can engage (FIGS. 8-11).
