Reservoir for rod-like elements for tobacco industry

An adjustable capacity reservoir for processing of rod-like elements for tobacco industry, comprising:

• a. a first inlet at a first reservoir side connectable to a first feeding duct for feeding a first stream of the rod-like elements to the reservoir through the first inlet;
• b. a second inlet at a second reservoir side opposite the first reservoir side connectable to a second feeding duct for feeding a second stream of rod-like elements to the reservoir through the second inlet;
• c. a receiving duct connectable to the reservoir for receiving the rod-like elements from the reservoir;
• d. a first chamber located between the first feeding duct and the receiving duct and having a first boundary surface for defining the capacity of the first chamber;
• e. a second chamber located between the second feeding duct and the receiving duct and having a second boundary surface for defining the capacity of the second chamber and being separated from the first chamber by a partition disposed therebetween;
• f. a first filling level sensing means coupled with the first chamber for sensing a filling level of the first chamber and including a displaceable first guiding surface having a non-blocking position and a blocking position for forming an obstacle to the flow of the second stream of elements from the second feeding duct through the second chamber to the first feeding duct;
• and
• g. a second filling level sensing means coupled with the second chamber for sensing a filling level of the second chamber and including a displaceable second guiding surface having a non-blocking position and a blocking position for forming an obstacle to the flow of the first stream of elements from the first feeding duct through the first chamber to the second feeding duct.
