<p>An arrangement at a slide (3) movable on a guide (1) and provided with longitudinal channels (6), in order to control with rolling elements (4), which travel continuously during operation in the slide (3), the slide at the guide (1). The invention is characterised in that the slide is equipped in connection with the relevant channel (6) with a roller pathway (8) of steel tape in the form of an infinite loop with straight sections (8a, 8b) adapted to the length of the slide, whereby one section (8b) that faces the guide forms a bearing roller pathway under the rolling elements (4) returning from the interaction with the guide. The first section (8b) is held by a spring (9) that acts between the slide (3) and the first section (8b). The continuously curved sections that join the straight sections of the roller pathway (8) extend outside of the ends of the slide and are surrounded each by a roller transfer (15) with a channel (16) open to the curved section of the roller pathway for transfer of the roller elements (4) from the first straight section to the second straight section, for the return of the rolling elements (4) following movement of the slide (3) along the guide (1).</p> |
