Control system for cigarette producing and processing machines or the like
First Claim
1. In a production line for rod-shaped articles which constitute or form part of smoker'"'"'s products, a combination comprising a machine for making rod-shaped articles, said machine having devices for draping flexible wrapping material around rod-like filler material for severing the draped filler material to form discrete rod-shaped articles and for conveying said discrete articles along a predetermined path, said devices having parts movable at a first speed and at a substantially higher second speed;
- prime mover means having variable-speed output means connected with said movable parts of said devices;
first speed increasing means for accelerating said output means to said first speed;
second speed increasing means for accelerating said output means from said first to said second speed at a slower first rate or at a faster second rate; and
means for restricting said second speed increasing means to acceleration of said output means at said slower first rate.

Abstract
A production line consisting of a cigarette making machine, a filter cigarette making machine and a packing machine or of a filter rod making machine and several filter cigarette making machines is controlled by a circuit which regulates the speed of the prime mover for the cigarette making machine or filter rod making machine in such a way that the speed changes gradually and smoothly from zero to a lower speed, from a lower speed to a higher speed, from a higher speed to a lower speed, from a higher speed to zero, or from a lower speed to zero. The changes in speed can be initiated by the operators or in response to signals which are generated by detectors serving to scan the operation of certain parts in one or more machines of the production line. The prime mover consists of a variable-speed motor, a constant-speed motor and a variable-torque clutch, or a constant-speed motor in combination with a variable-speed transmission.
