Description
APPARATUS FOR AND METHOD OF MANUFACTURING A FIRE
RETARDANT TEXTILE SHEET
This invention relates to a method of manufacturing a fire retardant textile sheet, and to apparatus for manufacturing such a sheet.
According to the present invention apparatus for coating an elongate sheet material with a solution comprises means for substantially continuously supplying an elongate sheet material, a means for drawing the sheet material from the supply means, a reservoir of solution to be applied to the sheet material, a movable sprayhead
located substantially within a spraybooth for coating the sheet material with a pre-determined density of spray solution as the sheet is drawn through the spraybooth, a means for drawing the sheet material past at least one drying means, the or each drying means being located downstream of the spraybooth to cause the solution which has been applied to the sheet material to dry leaving the sheet material with an enhanced or otherwise improved physical characteristic, and a means for storing the dry coated sheet material downstream of the or each drying means.
The solution preferably comprises a composition which, when coated on a sheet material and allowed to dry thereon, gives to the coated sheet material an Improved fire resistance over the uncoated sheet material.
The coating solution is preferably In liquid form at the time It Is sprayed from the movable sprayhead, but in certain embodiments within the scope of the present
Invention, the solution may be sprayed In powder or granular form, and may be converted into I iquld form by the drying means, the liquid being dried as the sheet material passes through the drying means.
The coating solution may be supplied from the reservoir by simple gravity action, but in a preferred embodiment
It Is supplied through a valve, the valve being controlled by a data processing device to ensure that the sheet material is coated with a substantially even predetermined density of solution.
The sprayhead is preferably movable back and forth across the width of the sheet material so that the sheet material Is coated with an even density layer of solution.
In one preferred embodiment the angle of the sprayhead with reference to a datum point is controlled in response to the position of the sprayhead across the width of the sheet so that the moving sheet material may be coated evenly. This actlon of the sprayhead may be most effective in embodiments where the speed of the sprayhead
Is not very much greater than the speed of the sheet material.
The sprayhead is preferable located within the spraybooth, the spraybooth being located a relatively short distance upstream of the or the first drying means.
The spraybooth is preferably substantially closed so that spray from the sprayhead Is applied to the sheet material passing through the spraybooth, but so that substantially all the airborne spray is confined to within the spraybooth. The spraybooth may be provided with a tray for collecting any drips of solution which may fall from the sprayhead, or any condensate of the solution.
If approprlate, such solution may be returned to the reservoir to minimise any waste.
The spraybooth may be manufactured from a two part construction comprising a galvanised steel exterior and a stalnless steel Interlor.
The drying means are is preferably located within a drying oven. Such a drying oven may comprise generally a box construction having a double skin Insulation wall.
Such an insulation wall may comprlse a mild steel plate / fibre glass Insulation / mild steel plate sandwich.
The drying means preferably comprises a plurality of heated drying elements positloned across the width of the sheet material, each element being spaced apart from the other along the length of the path of the sheet material.
The or each drying element preferably comprises a radiant heat drying element, with the radiating portion being directed towards the coated side of the sheet material.
The heat from each radiant element in one preferred embodiment Is provided by gas burners.
The drying oven is preferably connected to the spraybooth so that sheet material coated within the spraybooth Is drawn from the spraybooth direct to the oven.
In one preferred embodiment, the sheet material is drawn upwardly from a narrow opening formed through an upper part of the spraybooth, and into a vertical (tall) drying oven, such an oven having a series of drying elements arranged in a palr of stacks, so that the sheet can be drawn upwardly In front of the first stack, and downwardly behind the opposing stack. In such a case the sheet material may be turned at the top of the oven by means of an effective roller arrangement.
In a second preferred embodiment, the sheet material is drawn from a narrow opening formed through a side or end part of the spraybooth, and into a horizontal (long) drying oven, such an oven having a series of drying elements arranged in a array, so that the sheet can be drawn horizontally across the array, and out of the oven to the storage means.
The means for storing the substantially dry coated sheet material may comprise a storage roller. Alternatively, the storage roller may be replaced by a cutting arrangement, whereby the cut lengths of dry coated sheet material may be stacked or otherwise stored.
In certain embodiments the coated sheet material may be drawn from the oven direct Into a further processing apparatus. This will be Important where the sheet material needs to have several processes applied to It, whereby, for example, it may be coated with a first fire resistant solution, and then a second colouring material.
In a preferred embodiment the apparatus may be controlled by a data processing device.
Such a data processing device may be used to control the speed at which the sheet material is drawn through the apparatus, and the pressure with which the solution Is forced through the sprayhead (and thus the density of solution applied to the sheet materlal) and possibly the amount of radiant energy Issuing from the drying elements (to use the minimum amount of energy to dry the sheet material of solution), so that the sheet material which
Is drawn from the oven has the required density of solution applied to it (and consequently has the required enhanced or otherwise improved physical characteristic).
In a further preferred embodiment, the data processing device Is connected to a prlnter, selected details of the coated sheet material (such as the date the sheet material was coated, the time of coating, the batch number, the length of sheet material coated, the total weight of sheet material and coating, and the overall density) may be printed onto a label, this label being applied to the sheet.
In one embodiment, the data processing device may be programmed to operate the apparatus automatically, but so that an alarm may sound If the current density of coating varies more than, for example, 1 % from the required value.
According to another aspect of the present Invention a method of applying a coating to a sheet material comprises the steps of:
drawing an elongate uncoated sheet material from a
supply means In a substantially continuous manner;
applying sufficient tension to the drawn sheet
material so that it does not contain any creases;
drawing the sheet material into a substantially
enclosed spraybooth;
forcing a coating solution from a reservoir to a
sprayhead located within the spraybooth;
directing the spray forced through the sprayhead
onto the sheet material being drawn continuously in
front of the sprayhead, so that the sheet material
Is coated with an even pre-determined density of
coating solution;
drawing the coated shett material from the
spraybooth and into a drying oven;;
drawing the sheet material through the oven along a
path located adjacent at least one drying means so
that the heat from the drying means may dry the
solution applied to the sheet material, leaving the
sheet material with the required enhanced or
otherwise improved physical characteristic; and,
drawing the dry coated sheet material from the
drying oven to a storage means.
The method of applying a coating to a sheet material may be modified by the additional steps of drawing the dry coated sheet material from the oven into a secondary processing system and then drawing the sheet material from that said system to the storage means.
The method of applying a coating to a sheet material may also be modified by the additional steps of drawing the uncoated sheet material from the storage means Into a primary processing system and then drawing the sheet material from that said system to the coating means of the present invention.
Throughout this specification the term "sheet materlal" is intended to cover elongate textile sheets and fabrics, and other materlals such as articles in the nature of loose sheets such as scrims and groups of threads which are drawn through the apparatus in a sheet-like fashlon.
Two embodiments of the present invcention will now be described, by way of example only, with reference to the accompanying drawings in which:
Figure 1 is a part sectional plan view along the line 1-1 of a combined spraylng/drying machine with a vertical drying oven;
Flgure 2 is a part sectlonal rear elevation along the line ll-ll of the machine of Figure 1;
Figure 3 is an aoposing front elevation of the machine of Flgure 2;
Figure 4 is an end elevation of the machine of
Figure 1;
Figure 5 is a rear elevation of a second embodiment of a combined spraying/drying machine with a horizontal drying oven;
Figure 6 is a plan view of the oven of Flgure 5; and,
Figure 7 is a diagrammatic plan of a automatic control system for the machine of Figures 1 to 6.
Referring now to Figures 1 to 4 (but especlally to Figure 2), apparatus 1 for spraying a textile sheet material comprises generally a sheet supply means 2, a spray booth 3, a movable sprayhead 4, a drying oven 5 (having a drying means 6), a sheet driving means 7 and a sheet storage means 8.
The sheet supply means 2 comprises a horizontal roller 9 supported by a roller-support frame 10, the roller containing a substantial length of textile fabric sheet material in a roll.
In use the roller 9 rotates so that fabric 11 Is drawn off the roll In the direction of the arrow A. At or near the base of the roller support frame 10, is a fabric tensioning roller 12 so arranged to maintain the fabric in a relatively taut crease-free arrangement.
The fabric 11 having been drawn from the supply roller 9, and over the tensloning roller 12, passes over a further roller 13, this said further roller 13 being located adjacent the base of the spray booth 3 so that the fabric takes an upward path.
The spray booth 3 comprises a substantially enclosed cabinet 14 having a rearwardly facing opening 15. The movable sprayhead 4 (mounted upon a track located within the cabinet 14) Is arranged so as to direct spray through the opening 15 of the cabinet towards the path of the fabric.
A collecting tray 29 Is located substantially within the cabinet 14 so that any drips from the sprayhead or any condensation of the solution may be collected therein for later removal. In addition If the cabinet 14 is formed with an opening through its base, the tray may be located so as to substantially close that said opening.
The sprayhead 4 (or spray gun) is attached to a rod less cylinder and Is traversed horizontally back and forth across the width of the fabric material. In the present embodiment the sheet material is an ordinary domestic furnishing fabric which is coated with a fire retardant solution. However, almost any solution (or
Indeed a particulate material) could be sprayed onto a sheet materla (or an effective sheet material - such as scrum).
The fabric being drawn past the opening 15 of the cabinet 14, is coated with a fire retardant solution from the sprayhead 4. The spray solution 16 pumped through the sprayhead is confined to the reglon of the opening 15 by means of a removable protection shield 17.
The coated fabric sheet 11, still wet with solution 16, is drawn upwards away from the sprayhead 4, past four spaced apart radiant heaters 18. In this embodiment the radiant heaters 18 use gas as a fuel (supplied by a gas pipe 19) but in other embodiments electrically powered radiant elements could be used. In certain circumstances the use of radiant elements has been found to result In very significant energy savings.
By way of illustration radiant heat may cost. in the region of 3 cost units per hour to operate whilst nonradiant heat may cost as much as 35 cost units per hour.
The radiant heaters are all mounted upon the interior of the drying oven 5. The oven itself comprises a box-section framework (possibly measuring approximately 40mm x 80mm in cross sectlon) to which is fixed a double-skin wall comprising a mild steel plate.
fibre-glass Insulation/mild steel plate sandwich. The overall height of the drying oven may be approximately 3 metres, the width (front to back) approximately 2.5 metres and the length approximately 3 metres.
The fabric sheet 11 having been warmed by the four elements 18, Is turned around (to return to ground) by means of a palr of horizontal rollers 20 located at the top of the drying column (or oven) 5.
In another embodiment, the rollers may be replaced by seamless tubes and/or one of the rollers may be driven and provided with a spiral beading welded to its exterior surface to grip the fabric.
The top 21 of the drying oven 5 is provided with a ventilator or extractor means 22 to derive waste gases and fumes from within the drying oven.
The warmed fabric 11 Is substantially completely of fire retardant solution by means of four further gasradiant heaters 23 located in a spaced apart arrangement to dry the coated side of the fabric.
The dry coated fabric 11 then passes through a series of three horizontal drive rollers (24, 25 and 26) located at the base of the drying oven 5 to be recelved by a horizontal storage roller.
The drive rollers may be driven by a varlable speed motor 31 linked to the two lower rollers 24 and 26 vla a slipping clutch 32.
The storage roller 27 is supported by a resilient frame 28, the frame, in this embodiment, being connected to the base of the drying oven 5.
The spray cabinet 14 may be formed from a two part steel construction - the exterior aspect being formed from galvanized mild steel and the Interior aspect being formed from stainless steel.
Wlth reference to Figure 1 of the accompanying drawings access to the Interior of the drying oven 5 may be obtained, when the apparatus is not in use by means of a lockable door 30 located In the front panel of the oven.
Referring now to Figures 5 and 6 a horizontal drying oven 50 comprises generally a box construction having a pair of side walls 51 supporting a roof portion 52, the damp fabric being drawn from a supply roller 53 through the heated oven portion 30 and onto a storage roller 54.
The roof portion is provided with two types of ventilators 55 and an alr/vapour extractor means 56, and the front portion of the oven Is provided with a control panel 57 (this panel being linked electrically to a power supply, the sprayhead, and the drive rollers with lines 58).
In Flgure 7 a dlagrammatic arrangement Is shown for automatically controlling the coating of a solution onto a sheet material.
At the centre of the system is a data processing device such as a computer 100. The computer 100 is programmed to control the speed at which the fabric is drawn through the machine (by altering the speed of the drive rollers); the frequency at which sprayhead 4 oscillates along its track; the pressure applied to the solution (and thus the flow rate of solution through the sprayhead).
The invention is not restricted to the details of the embodiments herein. The Invention extends to any novel one, or any novel combination of the features disclosed in this specification, or to any novel one, or any novel combination, of the steps of any method disclosed herein.
