Abstract
Abstract The present apparatus is for coating one or more strands with fusible particles, which strands are fed in a continuous manner into the open top of a chamber having a fluidized bed of coating particles therein and which strands are heated in their travel to said fluidized bed whereby said particles are fused on said strands building up a coating on the strands which are fed from the open top of said chamber each through an air bearing guide to a heater, cooler and then to a take-up roll therefor.

Total Claims: 14
Claim 1
Independent Claim
104 words
An apparatus for coating strand material comprising an open top chamber, a porous plate extending across the interior of said chamber providing a bottom section and an open top section for containing coating material, means for supplying air under pressure into said bottom section whereby said air passes through said porous plate to said coating material, a guide roller in said top section, a heater in said top section whereby a strand of material can be fed into said chamber open top to said roller, through said heater to said coating material to be coated thereby and through the open top of said chamber.
Claim 2
Independent Claim
104 words
An apparatus for coating strand material comprising an open top chamber, a porous plate extending across the interior of said chamber providing a bottom section and an open top section for containing coating material, means for supplying air under pressure into said bottom section whereby said air passes through said porous plate to said coating material, a guide roller in said top section, a heater in said top section whereby a strand of material can be fed into said chamber open top to said roller, through said heater to said coating material to be coated thereby and through the open top of said chamber.
Claim 3
Independent Claim
139 words
An apparatus for coating strand material comprising an open top chamber for containing coating material, means for supplying air under pressure to said chamber below and into the coating material, a guide roller in said chamber, a heater in said chamber whereby a strand of material can be fed into said chamber open top to said roller, through said heater, to and through said coating material to be coated thereby and through the open top of said chamber, a second roller positioned exteriorily of said chamber and above the open top of said chamber for receiving and guiding the coated strand material, a funnel shaped guide positioned between said heater and said second roller and means for supplying air under pressure within said guide providing an air bearing guide for the coated strand material passing therethrough from said heater.
Claim 4
Independent Claim
139 words
An apparatus for coating strand material comprising an open top chamber for containing coating material, means for supplying air under pressure to said chamber below and into the coating material, a guide roller in said chamber, a heater in said chamber whereby a strand of material can be fed into said chamber open top to said roller, through said heater, to and through said coating material to be coated thereby and through the open top of said chamber, a second roller positioned exteriorily of said chamber and above the open top of said chamber for receiving and guiding the coated strand material, a funnel shaped guide positioned between said heater and said second roller and means for supplying air under pressure within said guide providing an air bearing guide for the coated strand material passing therethrough from said heater.
Claim 5
Independent Claim
164 words
An apparatus for coating strand material comprising an open top chamber for containing coating material, means for supplying air under pressure to said chamber below the coating material, a guide roller in said chamber, a heater in said chamber whereby a strand of material can be fed into said chamber open top to said roller and through said heater and coating material to be coated thereby and through the open top of said chamber, a second roller positioned exteriorily of said chamber and above one end of the open top of said chamber for receiving and guiding the coated strand material, a third guide roller positioned exteriorily of said chamber above the open top thereof on an opposite end of said chamber to said second roller, means for supporting a roll of strand material to be fed to said third roller, and means positioned between said supporting means and said third roller capable of straightening the strand material fed from said roll supporting means.
Claim 6
Independent Claim
164 words
An apparatus for coating strand material comprising an open top chamber for containing coating material, means for supplying air under pressure to said chamber below the coating material, a guide roller in said chamber, a heater in said chamber whereby a strand of material can be fed into said chamber open top to said roller and through said heater and coating material to be coated thereby and through the open top of said chamber, a second roller positioned exteriorily of said chamber and above one end of the open top of said chamber for receiving and guiding the coated strand material, a third guide roller positioned exteriorily of said chamber above the open top thereof on an opposite end of said chamber to said second roller, means for supporting a roll of strand material to be fed to said third roller, and means positioned between said supporting means and said third roller capable of straightening the strand material fed from said roll supporting means.
Claim 7
Independent Claim
193 words
An apparatus for coating strand material comprising an open top chamber for containing coating material, means for supplying air under pressure to said chamber below the coating material, a guide roller in said chamber, a heater in said chamber whereby a strand of material can be fed into said chamber open top to said roller and through said heater and coating material to be coated thereby and through the open top of said chamber, a second roller positioned exteriorily of said chamber and above one end of the open top of said chamber for receiving and guiding the coated strand material, a third guide roller positioned exteriorily of said chamber above the open top thereof on an opposite end of said chamber to said second roller, means for supporting a roll of strand material to be fed to said third roller, a plurality of said roll supporting means, rollers and said heater being positioned in series thereof laterally of and in said chamber whereby a plurality of strands can each be fed between a pair of said rolls over one of said third, first and second roller and through one of said heaters.
Claim 8
Independent Claim
193 words
