WIRE COATING PROCESS AND APPARATUS The present invention is related to apparatus for coating strand material with fusible coating material and is an improvement thereon.
The principal object of the present invention is to provide an apparatus for coating one or more strands continuously, economically and at relatively high speed through an open top chamber without sealing devices for the passage of the strands into and from said chamber.
A further important object of the invention is to provide an apparatus for coating multiple strands of material simultaneously which strands can be of the same or different materials and cross-sections or of uniform or non-uniform cross-section.
Another important object of the invention is to heat the strands within a fluidized bed in an open top coating chamber using heat from cooling means for already coated strands to prevent heat losses and which strands upon being .coatedare guided through a non-contacting stabilizer which removes non-fused coating particles from the strands.
Further objects of the invention will be in part obvious and in part pointed out in the following detailed description of the accompanying drawings, in which,
FIG. 1 is a top plan view of .anapparatus according to the present invention.
And F IG. 2 isa longitudinal sectional view taken on line 2- 2 of FIG. 1.
Referring now more particularly to the accompanying drawings in which like and corresponding parts are designated by the same reference characters, numeral 1 indicates an axle on .which are rotatably mounted a plurality of rolls2 of strand material 3 tube coated. As indicated in FIG. 1 there are a plurality of rolls 2 with elements for coating and conveying each strand 3 as one or more such arrangements can be usedand as they are all the same only one is described herein.
That is, each strand 3 passes through superposed rollers 4, 5, 6 and 7 for straightening the strand to remove undesirable curves therein.
Each straightened strand 3 passes over a guide roller 8 and then downwardly alongside an end wall 9 of the coating chamber. Said chamber also has a pair of side walls 10, and upwardly slanting end wall 11 with end walls 9 and llconnecting said side walls 10. End wall 11 has a vertical bottom portion 12. A-bottom 13 extends across and is attached to said end and side walls which are unconnected at their tops providing an open top 14 for said chamber. A porous .plate 15 extends from end wall 9 to the lower portion 12 of end wall 11 and to said side walls 10.
A guide roller 16 is rotatably mounted above'porous plate 15 adjacent end wall 9 with strand 3 passing underneath roller 16and then on an upward slant through a heater 17 preferably of a focused infrared type. 'As thestrand passes through the heater 17, said strand is heated to a temperature above the fusion temperature of the coating particles 18 in said chamber. The strand 3 leaving said heater pass through the particles 18 which touch the strand and are fused thereto whereby a continuous uniform coating is built up on the heated strand 3.
As the coated strand 3 leaves the coating particles 18 it passes through, but does not touch a funnel shaped bearing device 19 into the bore of which high pressure air is passed from tube 20 connected to a source (not shown) of .air under pressure. Said device 19 is necessary when strand 3 iseither line or has low tensil strength as said bearing device serves to stabilize the strands radial motion. Stronger strands can be stabilized by applying tension thereto as by keeping the strand taut, such as by adjusting the position of rollers 16 and 23 relative to one another.
After the coated strand leaves the bearing device 19, it passes through a post cure heater 21, which can be a tubular heater similar to heater 17 and said heater 21 serves to complete the curing of the coating material and/or to smooth its surface. The use of a post cure heater 21 depends on the coating materials properties.
The coated strand then passes through a cooling plenum 22 where high velocity air is passed along the strand to remove the heat of fusion therefrom.
Afier the cooling plenum 22, the strand 3 is then passed over an adjustably mounted guide roller 23 and then to a takeup coil 24 of said strand. Coil 24 is attached to an axle 25 driven in a counter clockwise direction by means (not shown) for drawing the strand '3 from roll 2 to roll 24. Roll 24 can be removed from axle 25 when desired for its end uses.
A blower 26 has its air admission opening connected by tube 27 to plenum 22 for drawing air through said plenum, which air is heated by the heated coated strand 3 and goes from blower 26 through the leg 28 of an inverted T-tube to its cross-head 29 which has air control valves 30 and 32 on its ends. A tube 31 connected to a further source of air under pressure (not shown) is attached to valve 30 while valve 32 is connected to tube 34 opening in the space between bottom 13 and porous plate 15 of said chamber. Tube 31 can be an air exhaust outlet.
An electric heater 33 is positioned in tube 34 for heating air passing therethrough.
The heated air from tube 34 passes upwardly through porous plate 15 and heats the coating particles 18 above said plate to a temperature just below their tacky point. Heating the coating particles 18 enables a lower power consumption by the strand heater l7 and also pemrits the strands to move at a higher velocity.
The term sh-and" as used herein is to be considered a generic term for metallic wire, plastics, textiles and other elongated materials. Material of irregular cross-section can be coated in the present apparatus by using properly designed guide rollers 16 and 23. For example, barbed wire, rope, ribbon, perforated strip, cable or other strand elements can be coated in the present apparatus or various combinations of strands can be coated at the same time. Thus for example, the strands 3 can be various size wires and the maximum number of strands is dependent only on the practical size of the strand supply and take-up equipment. When multiple wire are being coated, a differentcoating thickness may be obtained for each wire 3 depending on the speed of travel of the wire, for example about 500 to 600 feet per minute, and the temperature setting for heaters 17 and 21.
The coating particles 18 are moved by the air from porous plate 15 and their height is controlled by valve 32. Such particles may be any of the thermoplastic and thermosetting coating materials. Descriptions of examples of such materials and their use are -well known and U. S. Pat. No. 3,019,126 is referred to therefore only as an example thereof.
