<p>Free-flowing polymerisable or hardenable resin composition is fed between the top ends of two conveyor belts moving at identical speeds and maintained in contact over a certain vertical length under slight pressure, and having co-operating recesses along their whole length, each pair forming a closed mould for the article to be produced, the contact length and belt speed being selected so as to convert the resin composition into a dimensionally stable, but still elastic material by the time it is discharged at the bottom end of the contact.</p> |
