Arrangement for a drive mechanism (2) adapted for a line, a fishing net or some other object suitable for hauling, being effective by co-acting between a plurality of pressure devices (20) and a counter-pressure element (22) which can be moved in the feed direction of the object being hauled, the pressure devices (20) being distributed in a circle along the feed direction and being able to act in a substantially axial direction towards or away from the said counter-pressure element (22), for temporary automatically-controlled clamping of the object to be hauled between the said pressure devices (20) and the counter-pressure element (22) while a specific distance is being covered. The invention can be used for hauling objects with different shapes without, for example, any manual adjustment of the mechanism being required. Transverse to the feed direction, at least the pressure devices (20) have a substantially greater extent of pressure surface (20A) for co-action with an object to be hauled than they display in the feed direction. |
