METHOD FOR INTRODUCING FOAM MATERIAL INTO HOLLOW CHAMBER PROFILES, AND HOLLOW CHAMBER PROFILE

摘要

The invention relates to a method for introducing foam material (3) into hollow chamber profiles, in particular hollow window or door chamber profiles, wherein initially the hollow chamber profile (1), which comprises several hollow chambers (2, 2', 2"), is shaped by means of an extrusion method, and wherein subsequently, foam material (3) is introduced into at least one hollow chamber (2). According to the invention, the air (5) in the hollow chamber (2) displaced by the foam material (3) escapes via at least one venting channel (4) to at least one adjoining hollow chamber (2', 2"). The invention further relates to a hollow chamber profile (1).
