Abstract: Production of cigarette filter rod is controlled by monitoring the tow (12) or rod (18) to provide signals indicative of tow consumption rate and varying the composition of the rod in accordance with the signals, e.g. to maintain a constant proportion by weight in the rod of tow and a plasticizer applied to the tow by an applicator device (18). The tow feed rate or the plasticizer supply rate may be varied in accordance with the signals. The monitoring device may comprise a tow bale weight sensor (48), a rod scanning head (54), or a weight band (33,57).

Abstract: Methods and apparatus are provided for making a laminate which is used to form a corrugated outer shield (60) of a sheath system (50) for a lightguide fiber cable (20). A strip (81) of a corrosion-resistant metallic material having a relatively high elongation, an oxide surface layer (65) and a relatively coarse outer surface is preheated to a temperature within a predetermined range. Afterwards, a composite adhesive strip is brought into engagement with the metallic strip and moved between a pair of rollers (91--91) which are maintained at a first temperature and which causes the strips to be subjected to a predetermined pressure. Then the two strips are moved between another pair of rollers (97--97) which are at a second temperature greater than the first and which subject the strips to the predetermined pressure. The resulting laminate (61) is corrugated by a device (104) and formed into the outer shield (60) about an inner shield (51) which is made of a highly conductive metallic material.

Abstract: An apparatus for the application of an adhesive film strip about the edge of a shaped part of sheet metal comprises a pair of application roller which rolls on the adhesive tape about the metal sheet edge, imparting to the strip a U-shaped cross section. The adhesive film strip is originally on a carrier tape and is on a storage reel from which it is drawn off by conveying rollers. After being separated from the carrier tape, the adhesive film strip is fed via free-wheeling pre-folding rollers to a pair of application rollers, and the carrier tape is removed by means of further conveying rollers. The pair of application rollers and the pre-folding rollers can be swivelled together about an axis extending parallel with the shafts of the application rollers, and are at the same time resiliently displaceable in the direction of this axis. The distance of the application roller shafts from the said swivelling axis is adjustable in order to achieve a leading or a trailing run.

The apparatus includes a carrying frame, a conveyor line for handling the profiled metal cores, an adhesive-applying station in the carrying frame, tangentially extending feeders with conveying members for handling profiled facings to be applied to opposite sides of the profiled metal cores, which feeders are provided on the carrying frame behind the station in the direction of travel of the conveyor line and include spreading wedge assemblies for spreading angled side flanges beyond edges of side walls of the profiled metal core.

Abstract: The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers.

Abstract: Controlling the bending of an overlapping edge portion of a metal shield of a cable core by supporting one side of an edge portion at a position along its feed path and applying pressure against the edge portion immediately downstream of and in a direction opposite to the support. Bending of the edge portion occurs immediately it has passed the support while the support dampers resiliency in the edge portion to prevent or lessen springback. Apparatus for bending is placed immediately upstream of the overlapping die and preferably includes means to vary the applied pressure. Hence, the desired orientation of the bent edge portion is obtainable by varying the pressure dependent upon the actual orientation as the overlapped shield leaves the die.

Abstract: A machine for making packages with labels is provided. The packaging machine utilizes a supply of packaging material in the form of a length of plain plastic tubing and a supply of labels in the form of a continuous strip thereof. In a previous cycle of the machine, the tubing was heat sealed along a transverse strip near the leading edge thereof. The strip is subsequently advanced a predetermined distance between a first set of jaws which close, with a first sealing wire carried by one of the jaws then energized to seal a leading edge of the tubing which will form the next package. A knife severs the tubing below that seal and the upper edges of the severed section which has been advanced are engaged by clamps. These move apart with the jaws to open the upper edges, thereby enabling an article to be dropped into the resulting pocket in the severed package section. The jaws then close once again and a second sealing wire below the clamps seals the upper edges of the severed section.

Abstract: Tandem operations for manufacturing coaxial cable units include new and unobvious methods and apparatus for laminating an outer conductor, for drawing an inner conductor, for applying plastic discs to the inner conductor and for corrugating the outer conductor. Laminating the outer conductor is accomplished by passing a copper, copolymer adhesive, steel sandwich through three pairs of heated rolls. The heated laminate is passed over a roller designed to impart a three-dimensional curvature to the laminate. Then, the laminate is advanced in the manufacturing atmosphere and over another roller to remove the three dimensional curvature while the heat is removed. This produces a laminate which is essentially stress-free although composed of dissimilar materials. The inner conductor is drawn to a final diameter by an ultrasonically vibrating drawing die within a liquid medium which acts as a lubricant and as a cleaner to form a clean, smooth inner conductor.
