ABSTRACT:
The invention relates to a variable pitch conveyor or a chain in which the length of the links can be varied.
Each link includes a cross-bar T.sub.i mounted between longitudinal rocking bars B.sub.i that are interconnected by linked bars L.sub.i. The bars B.sub.i are integral with a toothed sector which controls the rocking of the bars by meshing with a moving rack adapted to follow, with a variable speed, the motion of the chain.
