ABSTRACT:
The apparatus feeds products in mutually spaced relation to a work station such that successive products are received thereby at substantially the same point of successive working cycles. The apparatus comprises a first conveyor arranged to receive a longitudinal row of products in which adjacent products are touching, and a second conveyor receiving products from the first conveyor and driven at a speed greater than that of the first conveyor. A plurality of photocell devices sense the position of products on the second conveyor relative to their theoretical desired positions appropriate to cause the products to be successively fed to the work station at the desired point of successive working cycles. Upon the difference between the actual and theoretical desired positions of the products on the second conveyor exceeding a predetermined value, the speed of the first conveyor is appropriately adjusted.
