The subject of the present invention is a process for the production of waterproof joint tape, which is used to close the. between the glass plates Glass roofs should serve the resulting joints and compared to the jointing with the known glass putty have the advantage that they have no cracks, easily and quickly applicable, against rain, heat and

ίο are resistant to cold and those between the joints located directly on the glass plates or glued to the filler, seal permanently.

The process for making the expansion tapes is as follows:

The appropriately broadly cut strips of canvas, jute or the like are poured into a mixture of 1 part by weight of white lead and 1 part by weight of water ( or

man Apply a third protein mixture with a brush on both sides of the ^1st band and rub the white lead well * "into the pores of the band Sides coated with a mixture of the following composition.

ι part by weight of melted resin and 2 parts by weight of turpentine are mixed well and then added 5 parts by weight of varnish and 6 parts by weight of white lead. The mixture is finally 0.5 parts by weight Stained dust color.

Applying the white lead to the in this way in two parts The fabric of the tape is required for the reason that if you put the whole on the Tape to be applied amount of white lead would be incorporated into the mixture mentioned, the latter form such a thick mass that one couldn't evenly cover the tape with her everywhere.

The fabric is impregnated with the aqueous lead emulsion mentioned but still for the purpose of making said resin oil mixture through the substance of the Tape is not recorded in too large a quantity, as this would completely remove the tape would be made unusable and unsuitable for further treatment.

Namely, the tape obtained through the above two manufacturing phases is eye-catching Conceived commercial purpose not yet usable without further treatment, since Both sides of the tape are adhesive and therefore work with the same special is almost impossible when the sun is shining. It is therefore necessary to consider one side of the Removing the adhesive properties of the tape, which is achieved by drying the tape will. The one coated with the aforementioned resin-varnish-turpentine-lead-white-mineral paint mixture But tape is again useless in such a dried state, since it is not only its own when it is dried. Lost adhesiveness, but has also lost its softness and flexibility. To the tape

To make it soft again, pliable, i.e. usable, it is soaked in water and, after it has become quite soft, taken out of the water and the surface freed from excess water by letting it seep away. The one, outer

. The side of the tape is then painted over with some known type of oil, which too the adhesiveness is reduced, the other,

ίο inner side of the same, however, again with the above, but made more viscous by adding a larger amount of white lead Resin-varnish-turpentine-white lead-mineral paint mixture coated. This mass forms the adhesive layer of the tape, which does not penetrate to the other side can, as the dried mass filling the pores of the tape, which at Soaking only softened but not resolved such penetration prevented. The waterproof jointing tape produced in this way can be stored in tin cans in ready-to-use for years State to be preserved.

Claims (1)

Patent claim: Process for the production of waterproof jointing tapes for glazing, characterized in that the appropriately cut tape is initially treated with an aqueous white lead emulsion, then while still moist with a known mixture of melted resin, turpentine, varnish, white lead and mineral paint and then dried in any way is then thickened after soaking in water on one side with an increased white lead content Resin-turpentine-varnish-lead-white mineral color mixture, on the other hand coated with an oil known per se to become.
