CHEMICAL SOLUTION PRE-DISCHARGING APPARATUS

摘要

PURPOSE: A chemical solution pre-discharging apparatus is provided to clean the external side of a priming roller by flowing solution which is discharged from a slit nozzle into a fluid injecting unit. CONSTITUTION: A priming roller(2) discharges a drug solution(R) from a slit nozzle(C1). A driving part rotates the priming roller. A cleaning bath(6) comprises a cleaning solution. The external lower part of the priming roller is dipped in the cleaning solution of the cleaning bath. A first fluid injecting portion(8) and a second fluid injecting portion(10) injects a cleansing solution and a dry solution the external side of the priming roller. The fluid removing unit collects the fluid for the cleaning solution or the dry solution.
