Claims
- 1. Synthetic covering product obtained from the process comprising the steps of:
- depositing a layer of plastisol onto a substrate;
- depositing a plurality of discrete particles into said plastisol layer;
- depositing a powder containing fusible particles compatible with said plastisol coated substrate and said discrete particles, said powder being deposited onto said discrete particles and plastisol layer in an amount effective to provide a smooth outer surface to the synthetic covering product upon the melting of said fusible particles and said powder being deposited by powder deposition means wherein no contact occurs between said powder deposition means and said substrate or said deposited layers; and
- heating said powder material to melt said fusible particles and thereby provide a smooth outer surface to the synthetic covering product.
- 2. Product according to claim 1 including the step of:
- compacting said discreet particles after the deposition of said powder layer.
- 3. Product according to claim 2 wherein:
- said compacting step is carried out at a temperature such that adhesion is precluded and such that surface homogenization is sufficient.
- 4. Product according to claim 3 wherein:
- said compacting step temperature is between about 120.degree. C. and about 170.degree..
- 5. Product according to claim 1 wherein:
- said plastisol is deposited in a thickness adapted to the particle size of said discreet particles to be deposited.
- 6. Product according to claim 1 wherein:
- said discreet particles are deposited in excess in the ungelled coated plastisol layer and wherein the excess is then removed.
- 7. Product according to claim 1 wherein:
- said discreet particles comprise fragments of PVC.
- 8. Product according to claim 1 wherein
- said powder is deposited by means of a rotary silk screen printing frame without contact between said substrate and said deposits of material and said silk-screen printing frame.
- 9. Product according to claim 1 wherein said heat treatment comprises:
- a setting operation at a temperature of between 160.degree. and 220.degree. C.
- 10. Product according to claim 1 including the step of:
- at least one surface treatment.
- 11. Product according to claim 10 wherein said surface treatment step comprises:
- embossing said deposited layers.
