Abstract
A fume extractor unit for the heaters of textile yarn or filament processing machines comprises a closed end container surrounding a heater and having a chamber closed by an insulated sealed door to allow for threading the yarn or filament through the heater, and an exhaust pipe communicates the chamber with a suction duct connected to extract fumes directly from the chamber and minimize condensation therein.

' e ere ces l UNITED STATES PATENTS 1 Claim, 1 Drawing Figure 1,731,290 10/1929 Boltz 34/86 X F UME EXTRACTORS FOR THE HEATERS OF TEXTILE PROCESSING MACHINES This invention relates to fume extractor units for the heatersof textile yarn or filament processing machines and is an improvement in/or modification of the invention described in US. Ser. No. 313416, now US. Pat.
No. 3,796,538 issued Mar. 12, 1974.
The invention as described in said US. Pat. No. 3,796,538 comprises a heater container closed at each end and surrounding the heater an insulated-sealed door or cow] for closing one side of a chamber in the container to allow. for threading the yarn or filament through the heater, an exhaust duct or hole and exhaust pipe from the door communicating with a main exhaust duct extending substantially parallel with the heater and insulating linings on the top and bottom walls of the chamber to prevent the loss of heat, the insulated seal on the door or cowl extending into the-chamber in contact with the linings and having flanges in engagement with the container walls to prevent the escape of fumes.
It has been found that with increased yarn speeds and with the yarn travelling downwards through the heater tubes that it is an advantage to exhaust the fumes directly from the heater tubes instead of through the door.
According to the invention a fume extractor unit comprises a heater container closed at each end, surrounding the heater and an insulated sealed door or cowl for closing one side of a chamber in the container to allow for threading the yarn or filament through the heater characterised by an exhaust pipe communicating with the chamber and with a suction duct common to a plurality of heater containers to extract fumes from the chamber.
The invention will be described with reference to the accompanying drawing showing a section of a heater container showing a door or cowl thereon for use in a fume extractor.-
As disclosed in said US. Pat. No. 3,796,538, a door D for a fume extractor chamber b is formed with an inner wall (1 defining a chamber 1 the door being extruded integrally. An extruded seal J" is mounted on the inner wall (1 of the door or cowl to extend longitudinally thereof and into the interior of the container B formed with the curved recesses b through which the yarn 1 travels and by which heat is transmitted from heater B to the yarn or filament, the recesses being formed in the rear wall of a chamber 12. The sides of the container B are lined with ceramic insulating material B and flanges a" on the seal a engage the walls of the container B, to prevent condensation on a portion of the seal contacting the lining material B The inner face of the seal d is provided with a reflecting metal strip :1
With yarn travelling downwards through the heaters condensation and loss of heat are prevented by the door seal a and the fumes are directly exhausted from the chamber b by providing an exhaust pipe D" passing from the chamber through the insulation material B and the container B in spaced relation to the closed door and connected to the suction duct D The pipe D is connected to the suction duct D by grommet connections (1.
Additional exhaust pipes D (shown diagrammatically) from the ends of the suction duct D may be provided adjacent one or both ends to pick up any fumes escaping into the room around the yarn during its passage into and from the heater tubes. Such fumes may escape from the upper inlet end due to convention currents from the lower end with the yarn.
What I claim is:
1. A fume extractor unit for a heater assembly of a textile yarn or filament processing machine comprising a heater, a container surrounding said heater closed at each end, heat insulation material lining said container. amd means defining a treatment chamber within the container through which the yarn or filament is passed for heat treatment by said heater, said chamber having at one side an opening and a normally closed insulated door over said opening, characterized by an exhaust conduit open at one end directly into said chamber and passing through said container insulation in spaced relation to said door opening for connection to an external suction duct, whereby fumes in the chamber resulting from heat treatment of the yarn or filament are directly exhausted from the chamber during processing.
