Subject: anti-friction system of elastic packings cooperating or not with an anti-friction rod made from synthetic material for the sealing of sliding PVC or aluminium sash frames with no use of auxiliary mechanisms. Optimal air sealing, water sealing, heat sealing and easy sliding due to the minimization of the friction of the packings 1 may be obtained by anti-friction elastic packings 1 and the potential use of an anti-friction rod 2 being made of synthetic material 2 and set between the frame of the sliding guide made of the profile 3 and the pane-bearing frame made of the profile 4. Advantages: abolition of the existing brush-like packings, and of the complicate expensive mechanisms destined for the removal of the elastic packings. The well known industrial mode which is so-far adapted for the construction of the sliding frames remains unchangeable. |
