<p>The conveyance assembly comprises a conveyor in the form of a pair of flexible looped members (5-8) (closed loop chains), which have two parallel overlapping portions the initial portions whereof are inclined to slightly converge in the direction of advancement. Mounted on the flexible members (5-8) are juxtaposed holder members (15, 16) which, in travelling through the inclined portions, are brought close to the opposite ends of the objects (P) to be conveyed until they engage over and under the same, holding them securely. The holder members are carried rotatably about a common rotation axis and operatively associated with cams (26, 27; 34, 35) which extend along the parallel portions of the flexible members (5-8) and control their rotation.</p> |
