Abstract
The mass of rod-shaped articles of the tobacco processing industry is ascertained by advancing a multi-layer mass flow of plain or filter cigarettes or analogous rod-shaped articles of the tobacco processing industry over one or more stationary and/or mobile weighing devices which generate signals denoting the combined weight of articles in successive increments of the mass flow. Such signals are processed with signals denoting the numbers of articles in the respective increments and/or with signals denoting the speed of advancement of the mass flow to generate signals denoting the average mass of discrete articles in successive increments of the mass flow.

A method of ascertaining the mass of rod-shaped articles of the tobacco processing industry, comprising the steps of advancing a multi-layer mass flow of rod-shaped articles in a predtermined direction along a predetermined path;
- weighing at least twice successive increments of the mass flow in at least one predetermined portion of said path;
- generating a succession of signals denoting the weight of successive increments of the mass flow and the mass of articles in the respective increments, including forming a succession of at least two signals each with each succession of at least two signals denoting the weight of the respective increments;
- and processing said succession of said at least two signals each into processed signals denoting the combined mass of articles in the respective increments of the mass flow.
Apparatus for ascertaining the mass of rod-shaped articles of the tobacco processing industry, comprising means for advancing a multi-layer mass flow of rod-shaped articles in a predetermined direction along a predetermined path;
- and means for weighing successive increments of the mass flow in at least one predetermined portion of said path and for generating a succession of signals denoting the weight of successive increments and the mass of rod-shaped articles in the respective increments of the mass flow, said weighing means including a plurality of weighing devices for the articles in said at least one predetermined portion of said path and each of said weighing devices comprising means for generating signals denoting the weight of successive increments of the mass flow.
A method of ascertaining the mass of rod-shaped articles of the tobacco processing industry, comprising the steps of advancing a multi-layer mass flow of rod-shaped articles in a predetermined direction along a predetermined path;
- weighing at least once successive increments of the mass flow in at least one predetermined portion of said path, said mass flow containing a predetermined number of overlying layers of rod-shaped articles, at least in said at least one predetermined portion of said path;
- generating a succession of signals denoting the weight of successive increments of the mass flow and the mass of articles in the respective increments;
- counting the numbers of articles in said successive increments of the mass flow;
- and processing said signals as a function of the monitored numbers of articles in the respective increments.
A method of ascertaining the mass of rod-shaped articles of the tobacco processing industry, comprising the steps of advancing a multi-layer mass flow of rod-shaped articles in a predetermined direction along a predetermined path at one of a plurality of speeds;
- weighing at least once successive increments of the mass flow in at least one predetermined portion of said path;
- generating a succession of first signals denoting the weight of successive increments of the mass flow and the mass of articles in the respective increments;
- monitoring the numbers of articles in said successive increments of the mass flow;

- measuring the speed of the articles in said path;
- generating second additional signals denoting the measured speed;
- and processing said first signals together with the corresponding first and second additional signals into signals denoting the average mass of articles in the respective increments of the mass flow.
A method of ascertaining the mass of rod-shaped articles of the tobacco processing industry, comprising the steps of advancing a multi-layer mass flow of rod-shaped articles in a predetermined direction along a predetermined path;
- weighing at least once successive increments of the mass flow in at least one predetermined portion of said path, said advancing step including pushing successive increments of the mass flow in said predetermined direction along said at least one predetermined portion of said path;
- and generating a succession of signals denoting the weight of successive increments of the mass flow and the mass of articles in the respective increments.
