PCT No. PCT/SE81/00268 Sec. 371 Date May 7, 1982 Sec. 102(e) Date May 7, 1982 PCT Filed Sep. 17, 1981 PCT Pub. No. WO82/00990 PCT Pub. Date Apr. 1, 1982.A device for use with conveyor tracks, comprising a continuous drive element (2), arranges so as to be moved by drive device (30) on a track with steering mechanisms for the drive element and load-carrying elements moving along the track, they being equipped with attachment devices (28) to the driving element in such a manner that they can accompany the same in their movements for the transport of materials. Drive element (2) has the shape of a band with corrugations, between which are constructed transverse grooves. The material in the drive element is hard and resilient and is preferably composed of a stiff plastic material and is dimensioned in such a way that the corrugations and hence the grooves in general retain their shape during the intended drive resistance and the intended load under the effect of the pointwise applying driving elements (30). At the same time, the corrugated shape of the drive element and its resilience are so designed that, in spite of its relative stiffness it can be given a continuous curvature in a number of planes or twisting from the effect of the steering mechanisms. |
