A device (1) to turn an object (2), said device comprising an object-supporting bight (3) of a flexible belt (4), line, chain or the like which is endless during the turning movement. After the bight (3) the two parts of the belt (4) run 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) which together with the belt support the object and the length of the belt is sufficient to encircle the object (2), or partly encircle a symmetrical portion thereof, in the intended direction of rotation. In a hypothetical encircling position of the belt with the support members (10-25) extending radially outwards, 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 along the circumference of the object. When the object is positioned on said bight (3) and its support members, if any, assume essentially the same position with respect to the object (2) as when the object was encircled by the belt, the objet will be turned in a controlled manner when the belt is set in motion in consequence of a turning movement imparted to one deflection means (8). |
