SEPARATING MEMBER FOR LAYING CURTAIN OF FILM Russian patent published in 1994 - IPC

FIELD: hydraulic engineering. SUBSTANCE: separating member includes flexible post 1 with branch pipe 2 for pressure-supply of air or fluid into hollow of post 1 and rigid post 3. Post 3 is of box-type cross-section and provided with hollow and supporting walls 5 with holes 6. Post 1 is connected with post 3 by means of flexible hinges 7, retainers and springs. Retainers are attached to post 1 and has lugs 10 passed through springs and holes 6.
