Abstract
Pileups of tobacco particles at or between the inlet of the draping mechanism and the stream forming station in a cigarette maker are ascertained by a device which monitors the density of successive increments of the cigarette stream prior or subsequent to trimming or the extent of deformation of the finger which compresses the trimmed stream in the garniture of the cigarette maker. The monitoring device generates signals which are utilized to automatically interrupt the admission of tobacco particles into the stream forming channel.
Claims24
A method of producing rod-shaped articles which constitute or form part of smokers' products, comprising the steps of establishing and maintaining a supply of tobacco particles;
- withdrawing from the supply a continuous layer of tobacco particles and converting the layer into a continuous stream;
- advancing the stream along a predetermined path;
- draping the stream into a web of wrapping material in a first portion of said path;
- monitoring the quantity of tobacco particles in successive increments of the stream in a second portion of said path upstream of said first portion and generating signals denoting the monitored quantities of tobacco particles;
- and automatically interrupting the converting step when a thus generated signal denotes that the quantity of tobacco particles in the corresponding increment of the stream exceeds a preselected value.
In a machine for the production of rod-shaped articles which constitute or form part of smokers' products, the combination of a source of tobacco particles;
- conveyor means defining an elongated path;
- means for withdrawing from said source a continuous layer of tobacco particles and for admitting the layer into said path so that the layer is converted into a continuous stream which advances lengthwise along said path;
- means for draping the stream into a web of wrapping material in a first portion of said path;
- means for monitoring the quantity of tobacco particles in successive increments of the stream in a second portion upstream of said first portion of said path, including means for generating signals denoting the quantity of tobacco particles in the respective increments of the stream;
- and means for automatically deactivating said withdrawing means to thereby interrupt the conversion of the layer into said stream when a signal denotes that the quantity of tobacco particles in the corresponding increment of the stream exceeds a preselected value.
