ABSTRACT:
The thrust bars (11), which are placed behind the product in the transfer phase from a first transport line (L1) to a downstream line (L2), have an adjustable stop (12) resting against the one side of the product in the direction of travel of this product. Articulated joints (10, 10′), connect the ends of the bars to corresponding points of the upper branch or the lower branch of a parallel pair of toothed belt conveyors (T, T′) fed on pulleys with horizontal axles, which are inclined at a right angle to the conveyors (T,T′) which bridge the area between the two transport lines and which with their one branch, work in the direction running from the upstream line to the downstream line at an identical speed to each other such as to be able to effect, with the above-mentioned bars, the transfer of products from one conveyor belt to the other by rear and side thrust. Guides (13, 13′) are provided parallel to the conveyor (T) connected to the outer edge of the junction area of the conveyor lines to guide the right-hand edge of the product in the working direction during the transfer phase, particularly when this product is very long.
