Abstract
The invention claimed here comprises a process for producing neoprene foam structures which are greater than four inches in diameter. The claimed invention also comprises a structure of neoprene with a thickness greater than about four inches composed of one continuous mass of adhesively bound neoprene particles.
Claims31
A process for manufacturing neoprene structures, which consists essentially of:
- (a) chopping neoprene foam into pieces;
- (b) mixing the chopped neoprene foam with an neoprene latex adhesive;
- (c) forming the neoprene mixture into a desired shape and structure and providing means by which said neoprene mixture can retain said shape and structure;
- and
- (d) drying the mixture.
A structure of neoprene consisting essentially of one continuous mass of neoprene latex adhesively bound neoprene particles.
Furniture having cushioning means, said cushioning means being composed of a structure of neoprene consisting essentially of one continuous mass of neoprene latex adhesively bound neoprene particles.
A process for manufacturing neoprene structures, which consists essentially of:
- (a) chopping neoprene foam into pieces and mixing the pieces of neoprene in a first container;
- (b) mixing neoprene latex adhesive an antifoam agent and an algecide together in a second container;
- (c) mixing the pieces of neoprene of step "a" and the mixture of step "b" together;
- (d) transferring the resultant mixture of step "c" into a mold;
- and
- (e) drying the neoprene mixture contained within the mold of step "d" by means of electromagnetic energy.
A process for manufacturing neoprene structures, which consists essentially of:
- (a) mixing pieces of neoprene foam, neoprene latex adhesive and an antifoam agent together;
- (b) transferring the resultant mixture into a mold;
- and
- (c) drying the neoprene mixture by means of electromagnetic energy.
