Abstract: 1,138,066. Tubular films. GENERAL ENG. CO. (RADCLIFFE) Ltd. 29 Nov., 1966 [9 Dec., 1965], No. 47393/65. Heading B5B. Apparatus for the manufacture of extruded plastic tubing by extrusion and stretching combined with applied external air cooling thereof followed by winding into roll form, is characterized in that the means for applying the external air cooling comprises an axial flow fan 14, 15, 16 with an annular nozzle 17 arranged co-axially of the tubular extrudate and means 18 for reducing the helical component of the air stream before it leaves the said nozzle. As shown, the extruded plastics tube 10 is upwardly extruded from die 11 and stretched and expanded in known manner. Surrounding said tube is a tubular frame 12 of an axial flow fan having mounting lugs 12a and including blades 13 arranged for downward flow. The casing 14 of the fan has an upper annular intake 15 and a curved annular upwardly directed outlet duct 16 ending in an annular nozzle 17 directed into the annular space between the tubular frame 12 and the plastic tube but at an angle directed against the tube. Within outlet 16 are baffles 18 arranged in known manner to reduce the helical component of the air stream before it reaches the annular nozzle. The fan rotor may be arranged to be driven by a belt 19 passing through the fan casing to a suitable power unit. The axis of the air flow passage between the intake and the outlet nozzle is substantially semi-toroidal. In operation, as the tube 10 is being extruded and drawn upwardly in known manner, the axial flow fan is able to produce an ascending annular envelope of air coaxial with the extruded plastic tube, which is not only more uniform as regards direction, velocity and volume than has hitherto been obtainable by the conventional fan and ducting, but has also a controlled small helical factor giving more uniform distribution of the cooling air, relative to the moving tube of film, than has hitherto been obtainable.

[Also in Division B8] The method of making a filamentous mat comprises winding two separate filaments or sets of filaments in distinct helical patterns on a rotating drum to form a cylindrical filamentous layer thereon, then cutting through this layer so that it can be removed from the drum and opened out to form a planar mat. As shown, Fig. 1, a glass furnace 10 is reciprocated on rollers 12 running on rails 14 and has a plate 26 in its bottom wall having a number of spinnerets from which individual glass filaments 28 descend to be grouped by rollers 30 and wound on the rotating drum 2. Further multifilament glass strands 32 are fed to drum 2 around wheels 46 carried by a member 50 on a carriage 36 which is reciprocated on a rail 34 by a reversing screw 38 and each wheel 46 collects a strand of filaments 32 from stationary glass furnaces 54. Filaments 28 and strands 32 are wound on the drum simultaneously but the upper feeder moves at e.g. 25 to 50 times the rate of the lower feeder. A binder is preferably applied during the winding on the drum by a reciprocating sprayer 64, Fig. 2 (not shown). When complete, the mat is slit axially and laid flat after which it is stretched and compressed and heated, dried or cured if the latter is necessary for the binder. The binder may alternatively be applied during or after stretching. Reference has been directed by the Comptroller to Specifications 891, 716 and 891, 715.
