    Previously-known state-of-the-art flanged connections for joining air duct elements do not lend themselves easily to fitting of a seal to render the walls of the air duct element leakproof. In order to produce already at the production stage of the flanged section (20) a seal (3) for the latter which mates with the relevant walls (1) of the air duct element, an insertion space is formed in the portion (2) of the section located under the wall of the air duct element, into which space is incorporated a seal (3) of elastomeric material, the free upper edge of which protrudes above the plane of the inner top side of said portion of the section.

    (L
    with
    The invention relates to devices that serve to connect parts of an air duct.
    The aim of the invention is to improve the sealing of the joint.
    The drawing shows the flange profile, cross section,
    The flange profile 1 for connecting the ends of the L-shaped duct contains a receiving cavity 2 | for the mounting corners and parallel to the outer 3 and inner 4 planes for gripping the duct end walls made in the inner plane 4 on both sides with a seal 6 “The seal 6 is made of elastomeric material and rolled into the groove 5, located near the receiving cavity 2, the edge of the groove 5 from the end of the plane 4 has a protrusion 7 to the outer plane 3, the end of the 8-outer plane 3 is bent to the sides y, opposite the inner plane 4.
    The flange profile 1 connects and seals the ends of the duct (not shown) as follows.
    The end of the duct (not shown) is reinforced between the outer 3 and inner 4 planes. The seal 6 rolled into the groove 5 ensures the airtightness of the connection.
    The protrusion 7 in front of the groove 5 with the rolled-in elastomeric material ensures the safety of the seal 6 when inserting the end of the duct into the flange profile and thereby improves the tightness of the connection.
    The bent end of the 8 outer plane 3 improves the process of inserting the end of the duct (not shown) into the flange profile 1 "

    Invention Formula
    Flange profile for connecting the ends of the L-shaped air duct cross-section, forming a receiving cavity for the mounting corners and parallel to the outer and inner planes for gripping the duct end walls on both sides with a sealing groove in the inner plane, characterized in that, to improve sealing connection, the seal is made of elastomeric material and rolled into a groove located near the receiving cavity, while the edge of the groove on the side of the plane’s end has stupas to the outer plane and the end of the latter is bent in the direction opposite to the inner plane
