Patent AT-E399897-T1: [Translated] DEVICE AND METHOD FOR FINISHING PIECES OF A SUBSTRATE, PARTICULARLY A TEXTILE SUBSTRATE, IN PIECES OR PARTS, UNDER HIGH PRESSURE

Device for the piece-wise or batch-wise refining of pieces of a substrate, in particular a textile substrate, under high pressure with a treatment medium, comprising: a substantially cylindrical pressure vessel ( 1 ), which is provided with a closable feed aperture ( 4 ) for placing the pieces of substrate in the pressure vessel ( 1 ); a pipe system ( 7 ) for feeding a treatment medium to and discharging it from the pressure vessel ( 1 ) under high pressure during treatment. The cylindrical pressure vessel is provided on at least one of the two end faces with an aperture that is closable by a lid ( 2, 3 ), which aperture forms the feed aperture ( 4 ). The device comprises retaining means for keeping the lid ( 2, 3 ) in place in a sealing manner during treatment, and the retaining means comprise a bounding frame ( 10 ) that is circumferentially closed, with two interconnected end pieces ( 11, 12 ) situated at a distance from each other, which end pieces in a closed position can be slid over the pressure vessel ( 1 ) and thereby retain the end faces of the pressure vessel ( 1 ) in the axial direction.
