摘要： The conveyor is constituted by an endless chain in the form of a horizontal closed loop. It is formed by at least one set of bars comprising a first series of bars and a second series of bars elastically deformable in the horizontal plane but rigid in the vertical plane, the bars of the first series being articulated on the bars of the second series, on one hand in the vicinity of the ends and on the other hand in the vicinity of the middle, thereby forming an uninterrupted sequence of curvilinear diamonds so that the four sides of a given diamond are obtained by means of four different bars. Means are provided for driving the chain, at low speed in at least two zones of a first type in which the diamonds are flattened perpendicularly to their forward direction, and at high speed in at least two other zones of a second type in which the diamonds are flattened in the forward direction. The speed of the chain varies in continuous manner in the portions of the chain situated between the two types of zones, the said bars bearing plate elements which partly overlap to form a horizontal receiving surface of continuous general configuration.
