In brief: Several ways
Adrenaline (epinephrine) constricts blood vessels to decrease the blood flow to a cut or wound, so the blood trying to clot there has an easier time doing so.
Epinephrine is believed to activate or encourage platelets to do their clumping and clotting actions. Epinephrine is also thought to activate blood clotting chemicals to help form clots with the fibrin and other particles in the blood.
