摘要： This invention provides a method and apparatus for injecting an additive into a stream of homogenized plastics material. The apparatus includes a homogenizing means such as a screw conveyor for the plastics material and at least one injector for injecting an additive, usually a colorant, into the boundary layer only of the homogenized plastics material prior to the latter being subjected to mastication in a gear pump. The additive is injected into the plastics material at such a position in the boundary layer that as the material passes through the gear pump the additive is mixed substantially wholly with the boundary layer of plastics material and for this purpose the injection of additive is at a position such that it passes through the gear pump in the region of the intermeshing gears of the pump.

摘要： This invention provides an apparatus for simultaneously producing, from a single source of homogenized plastics material, at least one product in which the plastics material is modified by the injection of an additive. The apparatus includes a mechanism, such as a screw extruder, for homogenizing the plastics material and a mechanism for dividing the stream of plastics material into at least two separate streams into one of which at least is injected an additive. The injection mechanism includes at least one hollow probe which terminates in the stream of plastics material to be modified and a dispersing mechanism for the additive, for example a gear pump, is provided. The streams of plastics material, modified and unmodified are then fed to a final product forming device, such as a die, in such manner that the streams can be individually extruded, or some at least of the streams can be combined in a die to produce an end product.

摘要： In an apparatus and a method for the curing of a continuous length of curable material, the length of material is passed through a curing chamber defined by a tubular body 47. This body 47 is disposed in the upper part of another heated tubular body 2 which contains a heat exchange liquid. This liquid is fed to one or more injectors disposed at one or both ends of the body 47, injected along the chamber and then allowed to drain back therefrom into the body 2. The body 2 contains a further tubular body 58 downstream of and partitioned from the tubular body 47. Body 58 also has an injector 60 through which water is injected to cool the length of material. Tubular body 47 may be provided with drain holes through which heat exchange liquid can be quickly drained at the end of a curing run. It may also be provided with air vents or a longitudinal slot in its upper part to release trapped air. Devices for wiping heat exchange liquid clinging to the cured material on emergence from the curing chamber are also provided. With this relatively compact arrangement curing may be achieved while thermal stresses in the apparatus are reduced.

摘要： A vacuum chamber seal at the entry or exit end of a vacuum chamber comprises two rollers 15, 16 one 16 of which is rotatable, defining an air lock gap. A guide tube 18, spaced from the gap but within the chamber, is constructed and disposed to promote and acceleration of the air flowing past it towards the gap resulting in a pressure drop on the roller side of the guide tube and a pressure differential across a web of material passing over the guide tube 18 and through the gap. This differential urges the web into initimate contact with the rotatable roller 16 to prevent oscillation of the web entering the gap.

摘要： A stream of homogenized plastics material is divided into stream parts 10, 11 and 12 and additive introduced to the external surface of at least one stream part 10, 12 either at or before a gear pump 1. Subsequent passage through the pump 1 mixes the additive in before the stream parts 10, 11 and 12 are recombined downstream of the pump. Stream parts 10, 11 and 12 may be separated by partition on approach to the pump gear and also by partitions 8 and 9 in the pump 1 itself.
