Sealing profile made of two materials

The invention relates to a sealing profile made of two materials for panes, facade panels]! ο »dgl», in particular executed in the form of a continuous band »

is an elastic frame or panel edging profile with a U-shaped cross-section known, which in its legs running in the longitudinal direction hollow · « has spaces (German patent specification 1 129 273) · These cavities have on one side of the handle Mn a slot-shaped opening are with a plastic sealant filled «To be with this« » known edging profile to achieve a seal »must pressurize it to such an extent that the plastic ^ iohtungpaasse from the cavities through the slit-shaped openings emerge and thereby a · Adequate sealing and adhesion cause »disadvantageous is particularly the high "^ pressure, However, compliance is not controllable. there is the · danger »IaS with something?

and the leakage of the sealant is prevented * Furthermore, it is disadvantageous that with a slight Release of the contact pressure z »B» due to deformation of the loading «» fixing elements and a reliable seal is no longer possible due to heat and fire resistance. ensures is »This well-known edging profile is also not suitable for picking up and sealing two panes forming insulating glass Storage of this known edging profile, the risk that the viscous * -elastic sealant can harden, especially in the area of the slot-shaped openings, so that even with a functioning slot opening. Escape of the sifting agent and thus a safe exit " sealing is prevented *

The task is therefore to create a sealing profile, in which disadvantages of the type shown are avoided and which cannot be damaged if the pressure is too high and which seals it when the pressure drops. so do not lose »

In a further development of the invention, a support profile can have at least one or more grooves for receiving slightly protruding plastic strips. The flexible support profile can also have at least one sealing lip opposite sides at least one respective ^D Non- 'bar borne by the manufacturing / a negative pressure in such a hollow cross-section ea is possible to reduce the lateral extent of the entire Abdichtprofiles · ^ s can be characterized in a comparatively narrow sealed column insert · without that the sealing strip compound suffers damage " ^ Ιτά then the negative pressure is removed again, so the sealing profile is pressed due to the internal tension of the Stüfcprofiles with the - ^ icht" strips against the side walls of the gap to be sealed "

Sine suitable embodiment consists in that a support profile having a U-fö'rmigen cross-sectional layer to make at least at the Innnenseiten the U-legs ^ has "It is also possible to interior" - and outside of the ^U-east en thighs be attached ^ ichtleieten respectively * - ^ If the U-Baeis is sufficiently wide, this cover profile can also accommodate two panes with a spacer, which then together form an insulating glazing "
