Sealing device for high pressure apparatus

摘要

A sealing device for high pressure apparatus designed for the treatment of fabric comprises a housing with two openings for inlet and outlet of the fabric, with two rolls contacting each other accommodated therein and adapted to rotate in the opposite direction for transporting the fabric being treated. Provided inside the housing are also two spaced apart bars arranged parallel to the rolls, each of the bars carrying a sealing member each of which contacts its respective roll. The bar ends made as trunnions rest upon bearings in the opposite walls of the housing and the overhung extensions of these trunnions protruding beyond the housing carry a suspension means for each of said two rolls, the suspension means being adjustable for length. The overhung extensions of the trunnions also carry a means for rocking motion of the sealing members relative to the axes of the bars. Such a construction of the sealing device ensures accurate adjustment of the sealing members with respect to the rolls.
