Abstract: Apparatus 2 for dosing a liquid colour formulation into polymer includes a weighing platform 4 which is supported on a pair of load cells 6 which are, in turn, supported on a base 8. A reservoir 12 contains liquid colour formulation 14. A pump 16 is arranged to pump liquid formulation, via a tube 20, to an extruder or injection moulding machine. Above inlet 24 is a delivery pack 26 which includes a bag-in-a-box arrangement 28. The delivery pack 26 includes a transfer pump 36 associated with an outlet of the receptacle 32. A transfer pump motor 38 is arranged to be engaged with the transfer pump 36 and operated so that liquid formulation can be pumped from the receptacle 32 into reservoir 12 across an air gap 13 defined between the transfer pump 36 and the inlet 24 of reservoir 12. There is no pipe, tube or other conduit through which liquid formulation passes on travel between delivery pack 26 and reservoir 12.

Abstract: Polymeric Materials An injector (14) for injecting liquid formulation into molten polymer includes a conduit (117) having regions (44, 46) which are secured within a wall of an extruder (19). Conduit (117) includes an annular collar (120) having an upwardly facing annular surface (122) which is arranged to bear against part of a sleeve nut (124). Conduit (117) is arranged within a port (125) which includes a screw-threaded wall (126). The sleeve nut (124) includes a cylindrical body (146) having an inwardly facing cylindrical wall which is arranged to define a cylindrical air gap (148) between itself and an outer wall (147) of conduit (117). Region (150) of the sleeve nut is screw-threadedly engaged in wall (126) of the extruder. In use, cool compressed air is introduced into the assembly in the direction of arrow (170) and it flows through the assembly to cool it.

Abstract: Injector (14) for injecting a liquid formulation into a molten polymer includes outlet (21) at one end and, at its other end, is arranged to be connected to upstream conduit (25) via a coupling housing (26) so that liquid formulation can pass from conduit into the injector, and further includes an elongate conduit (27) in which an elongate pin is slideably arranged being capable of expelling all liquid formulation from conduit. To address the risk the outlet could become blocked in use, whilst avoiding the need to depressurize and/or stop the flow or polymer in extruder (19), the injection apparatus includes a spool (34) which is rotatably mounted within wall (35) of the extruder and is arranged to be rotated about an axis which extends substantially perpendicularly to the elongate extent of the extruder through which a polymer stream (18) flows. The spool may be moved between a first configuration and a second configuration wherein a flow path is interrupted, but wherein molten polymer continues to flow in said polymer flow conduit.

Abstract: High pressure injection apparatus 2 for addition of a liquid formulation into a polymer melt stream at position 4 comprises pump assembly 6 upstream of an injector assembly 8. Pump assembly 6 is arranged to increase the pressure of the liquid formulation to a high pressure (e.g. up to 400 bar) and to accurately meter the liquid formulation to the injector assembly 8 which is arranged to inject the liquid formulation into the polymer melt stream. The polymer melt may be spun, for example to produce Fully Drawn Yarn (FDY) or Partial Orientated Yarn (POY). The pump assembly 6 comprises a syringe pump 12 which comprises a tube 14 in which a piston 16 is slideably received and is arranged to urge liquid formulation 18 within the tube to an outlet 20 which is coupled to an inlet of injector assembly 8.
