Device and method couple a substrate aafinar pieces, piece by piece or in batches, in particular a textile substrate, under high pressure.

摘要

Device for refining, piece-wise or batch, a substrate with a low-treatment high pressure, comprising: - a container substantially cylindrical pressure (1), which is provided with a feed aperture closeable (4) for placing the pieces of substrate in the pressure vessel (1); - a pipe system (7) for feeding and discharging the treatment medium pressure vessel (1) under high pressure during treatment; wherein the cylindrical pressure vessel is provided on at least one of the two end faces, an opening closable with a lid (2, 3), which aperture forms the feed aperture (4), and wherein the device comprises retaining means for holding the lid (2, 3) in place so as to provide sealing during treatment, characterized in that the retaining means comprise a bounding frame (10) which is circumferentially closed, with two interconnected end pieces (11, 12) positioned so as to keep a distance apart, and said end parts in closed position can slide on the pressure vessel (1) and thereby retaining the end faces of the pressure vessel (1) in the axial direction.
