Abstract

IN APPARATUS FOR PRODUCING TOBACCO SMOKE FILTER RODS FROM A CONTINUOUS LENGTH OF BANDED FILTER TOW AND HAVING A SET OF TENSION ROLLS, A SET OF FEED ROLLS, A PLASTICIZER APPLICATION DEVICE FOR APPLYING PLASTICIZER TO THE BANDED FILTER TOW, A SET OF DELIVERY ROLLS, A COLLECTING TRUMPET FOR INITIATING CONDENSING OF THE BANDED FILTER TOW TOWARD A ROD-LIKE CONFIGURATION, A FOLDER TONGUE IMMEDIATELY ADJACENT THE COLLECTING TRUMPET FOR FURTHER CONDENSING THE BANDED FILTER TOW TO THE ROD-LIKE CONFIGURATION, A GARNITURE DEVICE IN WHICH THE FILTER TOW IS MOVED AND WRAPPED, A SEVERING DEVICE, AND CONVEYORS FOR CONVEYING THE SEVERED FILTER RODS AWAY FROM THE APPARATUS, THE IMPROVEMENT COMPRISING AN AIR SENSING DEVICE CONNECTED TO THE FOLDER TONGUE FOR SENSING RESISTANCE TO FLOW OF AIR THROUGH THE

FILTER TOW PASSING THROUGH THE FOLDER TONGUE AND FOR GENERATING A SIGNAL PROPORTIONAL TO THE DENSITY OF THE TOW PASSING THROUGH THE FOLDER TONGUE. THE SIGNAL GENERATED IS COMPARED WITH A VOLTAGE SET-POINT WHICH REPRESENTS A PREDETERMINED PRESSURE DROP, HENCE PREDETERMINED DENSITY OF THE FILTER TOW, AND SHOULD BE GENERATED SIGNALS COMPARED DIFFER FROM THE VOLTAGE SETPOINT, THE DELIVERY ROLLS, FEED ROLLS AND TENSION ROLLS ARE EITHER SLOWED OR SPEEDED UP RELATIVE TO THE SPEED OF THE FILTER TOW MOVING THROUGH THE GARNITURE DEVICE SO AS TO CAUSE EITHER A GREATER OR LESS AMOUNT OF FILTER TOW TO BE FED INTO THE FOLDER TONGUE.

Filed May 6, 1974, Ser. No. 467,524 Int. Cl. 132% 23/00 US. Cl. 93-l C 2 Sheets Drawing. 20 Pages Specification An apparatus for producing tobacco smoke filter rods from a continuous length of banded filter tow and having a set of tension rolls, a set of feed rolls, a plasticizcr application device for applying plasticizer to the banded filter tow, a set of delivery rolls, a collecting trumpet for initiating condensing of the banded filter tow toward a rod-like configuration, a folder tongue immediately adjacent the collecting trumpet for further condensing the banded filter tow to the rod-like configuration, a garniture device in which the filter tow is moved and wrapped, a severing device, and conveyors for conveying the severed filter rods away from the apparatus, the improvement comprising an air sensing device connected to the folder tongue for sensing resistance to flow of air through the filter tow passing through the folder tongue and for generating a signal proportional to the density of the tow passing through the folder tongue. The signal generated is compared with a voltage set-point which represents a predetermined pressure drop, hence predetermined density of filter tow, and should the generated signals compared differ from the voltage setpoint, the delivery rolls, feed rolls and tension rolls are either slowed or speedcd up relative to the speed of the filter tow moving through the garniture device so as to cause either a greater or less amount of filter tow to be fed into the folder tongue.
