Machine for the production of filter rod sections or the like

Abstract

Abstract FILTER ROD SECTIONS ARE PRODUCED BY MOVING A TOW OF FILAMENTARY FILTER MATERIAL PAST A DEVICE WHICH SHOWERS THE FILAMENTS WITH ATOMIZED PLASTICIZER AND BY THEREUPON CONVERTING THE THUS TREATED TOW INTO A ROD-LIKE FULLER WHICH IS WRAPPED TO FORM A ROD. THE LATTER IS SEVERED TO YIELD A SUCCESSION OF FILTER ROD SECTIONS WHICH ARE TRANSPORTED BY A FLUTED DRUM TO STORAGE OR TO A MACHINE FOR THE PRODUCTION OF FILTER-TIPPED SMOKERS, PRODUCTS. GROUPS OF FILTER ROD SECTIONS ARE WITHDRAWN FROM THE FLUTES OF THE DRUM AT REGULAR INTERVALS FOR WEIGHING TO THUS DETERMINE THE QUANTITY OF FILTER MATERIAL AND/OR PLASTISIZER. THE RESULTS OF THE WEIGHING OPERATION ARE UTILIZED TO ADJUST THE FEEDING MECHANISM FOR THE TOW AND/OR PLASTICIZER IF THE MEASURED QUANTITIES DEVITE FROM THE DESIRED QUANTITIES. THE FEEDING MECHANISM FOR THE TOW EMPLOYS ROLLS WHICH CAN BE DRIVEN AT A VARIABLLE SPEED TO THEREBY SUBJECT THE FILAMENTS OF THE TOW TO A MORE OR LESS PRONOUNCED STRETCHING ACTION. THE FEEDING MECHANISM FOR THE PLASTICIZER EMPLOYS A ROTARY BRUSH WHICH REMOVES PLASTICIZER FROM THE PERIPHERY O A DRUM DIPPING INTO A SUPPLY OF PLASTICIZER, AND A VARIABLE-SPEED DRIVE FOR THE DRUM.
