Abstract
Abstract WATER-SOLUBLE TAPE IS MOISTENED TO MAKE IT TACKY, IS TROUGHED, AND IS MOVED PAST A SEED-DISPENSING STATION WHERE AT SPACED INTERVALS ONE SEED AT A TIME (OR ONE GROUP OF SEEDS AT A TIME) IS DEPOSITED IN THE TAPE. THE TAPE IS THEN CLOSED TO ENCAPSULATE THE SEED AND WOUND AROUND A CORE. THE SEEDS ARE DISPENSED BY A ROTARY DEVICE WITH NOZZLES THAT PASS OVER A SEED TRAY, PICK UP ONE SEED AT EACH NOZZLE BY VACUUM, AND DROP THE SEED UPON RELEASE OF THE VACUUM.
