Device and method for masking securing boreholes in rims during the coating thereof

Abstract

A device for masking securing boreholes in rims with masking elements having a storage container for the masking elements, a pressure generation unit, a connection unit connected to the storage container and an at least substantially tubular discharge device, which is secured at one end to the connection unit and which has a discharge opening at the opposite end for discharging the masking elements. The discharge device has a tube wall in which a channel for conducting a fluid is formed, the channel being connected to the pressure generation unit. The tube wall consists at least partially of an elastic material, through which the channel runs or in which a cavity connected to the channel is formed, such that, when the pressure of the fluid is changed, the tube wall deforms and releases the clamping on the masking elements. The connection unit and the discharge device are formed preferably as one piece in a 3D printing method.
