Title: Coating sheet materials with thermoplastic particles
Inventor: SMITH ROBERT LEWIS
IPC: B05D1/32
Filed: 1963-10-07
Abstract: A process in which particles of thermoplastic material containing magnetic material are magnetically attracted to a sheet material e.g. paper, cardboard, fabrics, comprises passing the sheet material above a mist of the particles and below one or more magnets and bonding e.g. by heating, the particles to the sheet material while held thereon.  The mist may comprise a fluidized bed of the particles which may be formed by random ejection of the particles from a spray gun.  After the particles have been attracted to the sheet, the sheet may be reversed, the particles then being held thereon by gravity, and are bonded thereto by heating.  The sheet material 4 may be passed around a rotating drum 2 in which are mounted one or more magnets 1 and which is above a fluidized bed in tank 3 of the particles, the sheet rotating with the drum and while in contact therewith the sheet and particles held thereon is subjected to radiant heating from heaters 6 to fuse the particles and bond them to the sheet.  The particles may be attracted only to a part of the sheet material, e.g. in patterns, designs, figures, letters and other shapes, the sheet being moved in contact with the one or more magnets to shaped that magnetic attraction sufficient to attract particles to p  the sheet occurs only over the parts of the sheet to which the particles are to be bonded.  The sheet may move with and in contact with the one or more magnets.  After the application of particles to one side of a sheet, the sheet may be turned and particles applied to the other side.  The thermoplastic material may be a vinyl acetate homopolymer or copolymer, acrylate homopolymer or copolymer, or polyethylene.  A laminate may be produced by pressing a sheet material to the thermoplastic particles while soft e.g. using a hot calender.  Thermoplastic particles may be applied to both the surfaces to be bonded.
