Abstract
A method of manufacturing a rubber product by bonding thin pieces on a manufacturing table includes an adhesion prevention treatment step of treating uncrosslinked rubber powder to prevent mutual adhesion, a first raw rubber powder supply step of supplying raw rubber powder, treated for adhesion prevention, onto the surface of the manufacturing table, a first crosslinking step of irradiating with an electron beam to crosslink the irradiated portion, a post-treatment step of aligning the surface of the crosslinked portion with the surface of the manufacturing table, a second raw rubber powder supply step of supplying the raw rubber powder onto the surface of the manufacturing table, including the surface of the crosslinked portion, and a second crosslinking step of irradiating with an electron beam to crosslink the irradiated portion. The post-treatment, second raw rubber powder supply, and second crosslinking steps are sequentially repeated to bond the thin pieces.
