Method to feed and form organized groups of smoking articles, providing to feed a plurality of pockets of a transfer conveyor with pockets moved step-wise, thrusting said organized groups of smoking articles, by means of thrusters actuated independently from each other, in a direction of transfer and through respective forming drawers, into said pockets on the basis of a predefined production rhythm. The method provides, in the event of obstruction, stoppage or blockage of a forming drawer, to vary the operating speed of the thrusters associated with the other forming drawers in coordination and in synchrony with the step-wise feed speed of said transfer conveyor with pockets, in order to obtain an effective production rhythm equal or near to said predefined production rhythm.

The object of the invention is a forming and transporting apparatus for conveying rod-like articles and for forming groups of the rod-like articles of the tobacco industry, comprising transport units, whereas a transport unit comprises a transport carriage adapted to move along a path, and a transport tray provided with a number of transport grooves adapted to hold the rod-like articles, whereas the tray is fastened to the transport carriage, whereas the transport tray is divided into two transport sections which are adapted to change the reciprocal position between an open configuration in which the transport grooves are situated substantially in one plane and a closed configuration in which the transport grooves are situated in two planes being substantially parallel to each other.

A method of emptying trays filled with rod-shaped articles produced in the tobacco industry, which consist of the following stages: the trays designated for emptying are conveyed to the input area of a hopper containing adjacent channels separated by dividers; the rod-shaped articles are transferred from the tray to the channels of the hopper using support plates; the channels of the hopper are filled with the rod-shaped articles; the support plates are retracted from the channels of the hopper; the channels of the hopper are successively emptied into a chute adapted to move between channel outlets of the hopper; finally, the rod-shaped articles are transferred from the channels of the hopper and through the chute to the discharge conveyor moving towards the receiving device. The method is further characterized in that during emptying at least one channel (7) of the hopper (2), the hopper (2) moves linearly in the direction (S2) opposite to the direction (T) in which the rod-shaped articles are transported by the discharge conveyor (19); and after the channel (7) has been completely emptied, the hopper (2) moves in the direction (S1) concurrent with the direction (T) in which the rod-shaped articles are transported by the discharge conveyor (19), until it achieves a position in which the outlet of the next channel filled with rod-shaped articles is aligned with the inlet (21) of the chute (20), whereas the hopper (2) moves at a variable velocity when moving in the direction (S1) concurrent with the direction (T) in which the rod-shaped articles are transported by the conveyor.
