Apparatus for Applying a Flowable Material to an Inner Wall of a tube

Abstract

The present disclosure generally relates to an apparatus for applying a flowable material to an inner wall of a tube (600), comprising: a controller (100), a source device (200), and a motion driving device (300) which are outside the tube (600); and a motion and operation device (400) releasably insertable into the tube (600), the source device (200) is configured to selectively feed the flowable material to the motion and operation device (400) under control of the controller (100), the motion and operation device (400) comprises a spray cup (463) such that when the spray cup (463) is rotated, the flowable material fed into the spray cup (463) can be radially spun out of the spray cup (463), the motion driving device (300) is configured to enable the motion and operation device (400) to be movable in the tube (600) when it is inserted in the tube (600).
