The heaters of textile filament processing machines have been arranged vertically and it has been proposed to remove fumes from upper ends of the heaters through suction cowlings connected to extractor fans.
The heaters are normally housed in a boxlike container having an open front closed by a door to allow for threading up the filament therein.
It has also been proposed to save headroom by arranging a plurality of heaters through or around which the filament passes at an inclination to the vertical which permits the escape of fumes along the length of each heater.
The object of the present invention is to provide an extractor extending the length of each heater to remove the fumes as they emerge therefrom.
The invention comprises a sealed hood or door for closing a recess in a heater container, the hood or door being formed with a longitudinal chamber connected through central ports or holes to a compartment in the heater container through which the yarn or filament passes and to exhaust ports in communication with an exhaust suction pipe or duct into which the fumes from the yarns or filaments are withdrawn.
The invention will be described with reference to the accompanying drawings:
FIG. 1 is a front elevation of a filament heater;
FIG. 2 is a side elevation enlarged of part of FIG. 1;
FIG. 3 is a side elevation partly in section on looking from left to right in FIG. 2;
FIG. 4 is an end elevation of a heater container show ing a door or hood thereon;
FIG. 5 is a section on line 55 FIG. 2;
FIG. 6 is a plan of same;
FIG. 7 is a section through a modified door and cowl having an inner wall extruded integrally therewith.
A textile processing machine draws filaments 1 from bobbins A on a creel and the filaments from each pair of bobbins pass through a heater B and are wound onto packages C in known manner. In order to save headroom it has also been proposed to arrange the heaters at an inclination as shown in FIG. 2. The filament heaters B are housed in box like containers B and due to increasing yarn speeds the length of the heaters have been increased to compensate for the increased speed and inclined to the vertical to save headroom.
Each heater container B is provided with a door or cowl D, preferably in the side of the container B to allow for threading the filaments therethrough.
The yarn or filaments pass, preferably upwards, through a recess 12 in the container B the recess extending longitudinally the length of the container.
The door or cowl D is hinged on arms a to the container B. The door or cowl is formed with an inner wall d defining a chamber d extending longitudinally thereof. The inner wall d and the door may be extruded integrally as shown in FIG. 7.
A curved strip of ceramic or other heat insulating material d is riveted to the inner wall d to extend longitudinally of the door or cowl and into the recess b which is also correspondingly curved, over which the yarn travels and by which heat is transmitted to the yarn or filament from the heaters. The insulating strip d" is provided to reduce heat loss from the heaters. A seal a is provided along each side of the door or cowl to engage the sides of the container B, the ends of the chamber d being closed.
Two holes or apertures d are provided in the inner wall d giving access to the chamber d and an exhaust tube d connected by a flexible tubing d to a suction exhaust duct d. A fan (not shown) creates a suction in the exhaust duct d which draws fumes from the chamber b together with air from the ends of the chamber b, through the holes d in the inner wall d and out through the tubes d d By providing the holes d midway along the inner wall d the air and fumes drawn into the chamber d are heated during their passage along the recess b thereby reducing or preventing condensation of oil or moisture out of the fumes during their passage through the chamber d on their way to the exhaust tube a and tubes d and into the exhaust duct d 7 which is common to all the heaters.
In order to thread the filaments through the heater compartments the door or cowl D is pivoted to an open position as shown dotted in FIG. 4 by handles d on the door or cowl.
Two or more heaters may be arranged in tandem if required and although the door or cowl has been described for use on inclined heaters it is equally applicable to vertical heaters in which the yarns or filaments travel therethrough vertically.
What I claim is:
l. A fume extractor unit for the heaters of textile yarn or filament processing machines havingfilament heaters inclined to the vertical and. a container for each heater having a longitudinal recess therein along which the filaments pass out of contact with the heaters, the invention comprising a sealed door for said recess pivoted on the container, longitudinal wall means on the door constructed and arranged to define a longitudinal chamber in said door, aperture means in said wall means to give access from the recess to the chamber, exhaust tube means connecting said chamber to a suction exhaust duct to draw fumes from the recess, and longitudinally extending heat insulating means mounted on said door and projecting into said recess in the container to reduce loss of heat from the heater.
2. A fume extractor as defined in claim 1, wherein said heat insulation means is a strip of heat insulation material extending along the inner side of said door.
3. A fume extractor as defined in claim 2, wherein said heat insulation strip is mounted on said wall means.
4. A fume extractor unit as defined in claim 1, having resilient strips along each side of the door for forming a seal between the closed door and the container.
5. A fume extractor as definedl in claim 1, having arms connected to the door by which said door is pivoted on the container.
6. The fume extractor defined in claim I, wherein said heat insulating means comprises a strip of ceramic material extending along said door and facing said recess.
