PCT No. PCT/SE93/00284 Sec. 371 Date Sep. 29, 1994 Sec. 102(e) Date Sep. 29, 1994 PCT Filed Apr. 2, 1993 PCT Pub. No. WO93/19988 PCT Pub. Date Oct. 14, 1993.A device (1) to turn an object (2), said device comprising an object-supporting bight (4), a continuous belt, line, chain or the like. After the bight (3) the two parts of the belt (4) extend into parts (5, 6) each one of which travels past a deflection means (8, 9), such as a roller. On the lower side of said parts they are united by means of a lower belt part (7). The belt (4) is provided with support members (10-25) support the object, and the length of the belt is sufficient to fully encircle the object (2), or at least partly encircle a symmetrical portion of it, in the intended direction of rotation. In a hypothetical encircling position of the belt, the support members (10-25) extend radially outwards, and these members are configured to essentially fill up the space between the belt itself and the object, and each support member abuts against the object (2) at least at one point. When the object is positioned on said bight (3 ) and its support members, the belt assumes essentially the same position with respect to the object (2) as when the object was encircled by the belt. In this way, the object will be turned in a controlled manner when the belt is set in motion through turning the deflection means (8). |
