ABSTRACT:
A transporting arrangement for delivering products which are deposited at a first cycle at one end of an endless conveyor at a second higher cycle from the other end thereof. The arrangement includes an endless conveyor having an upper run moving at a first speed onto which the products to be transported are placed uniformly spaced from each other and a first chain having a run parallel to the upper run and movable in the same direction and at the same speed as the upper run. A second chain, driven at a higher speed than the first speed, carries on a run parallel to the upper run a plurality of entrainment members, each movable from a rest to an operating position, and moved to the latter position when the respective entrainment member overtakes one of a plurality of actuating means fixed equally spaced from each other to the first chain. The entrainment members in their operating position project upwardly beyond the upper run to thereby transport the products thereon at the higher speed to the other end of the upper run of the endless conveyor.
