Abstract

The apparatus is formed of two identical devices (A, A′) installed mirror image-fashion, each of which is equipped with a pressure bar (19, 19′) fitted to overhang the relevant lateral toothed conveyor belts (T, T′) which move and recircle the sai bars, and which are in their turn activated by relevant motors (8, 8′) with electronic speed and phase control governed by one programmable processing unit (26). When the length of the products (P) is less than the length of the straight branches of the conveyors moving the said bars, the two devices are installed mirror-image fashion, with the axles of the pulleys of one conveyor aligned with those of the corresponding pulleys of the other conveyor. In this position, the bars (19, 19′) of the two devices alternate in taking, moving foward by pushing and the final placing of the product in the workstation (K). However, when the length of the products exceeds the length of the said conveyors moving the bars, the possibility is offered of acting on both means, allowing anticipation of the longitudinal position of one device in relation to the other, so that the products are firstly taken by the bar (19′) of device (A′) working in advance and are transferred from it in phase to the bar (19) of the downstream device (A), which in turn provides for the transfer and phased placing of the product in the workstation (K).
