In order to seal the corner joint of an elastoplastic tape placed as a spacer on a glass pane, a film strip is pressed with a first portion of its length against the first leg section of the spacer and the protruding portion of the film strip is wrapped around the corner and pressed against the second leg section. For the purpose of automating this process, the film strip is severed mechanically from an automatically supplied film tape and held via a transfer apparatus which thereafter presses the film strip with the first portion of its length against the first leg section. The portion of the film strip protruding freely over the corner is wrapped around the corner via a pressure carriage and pressed by tautening against the second leg section of the spacer.

The sealing apparatus of claim 5, wherein the pressure carriage comprises a roller member operable to wrap the severed film strip around the corner joint of the spacer and to press the second portion severed film strip against the spacer second leg. 13. The sealing apparatus of claim 12, wherein the pressure carriage further comprises a smoothing plate to compress the corner joint of the spacer prior to the pressing of the second portion of the severed film strip against the second spacer leg. 14. The sealing apparatus of claim 5, wherein the supply tape includes an adhesive layer disposed on a side of the substrate such that an adhesive-free edge strip is defined on either side of the adhesive layer. 15. The sealing apparatus of claim 14, wherein the side of the substrate containing the adhesive further includes a protective film covering the adhesive. 16. The sealing apparatus of claim 15 further including a deflection roller operable to remove the protective film from the tape supply film and a disposal roller configured to collect the removed protective film. 17. The sealing apparatus of claim 5, wherein the clamping apparatus and the transfer apparatus cooperate to hold the tape supply film during severing of the film. 18. A sealing apparatus for sealing a corner joint of a glass pane spacer including a first leg and a second leg connected connect along the corner joint, the apparatus comprising: a supply reel configured to hold a supply of film tape, the film tape comprising at least one diffusion tight layer;a controlled tape drive configured to advance the film tape from the supply reel;a clamping apparatus oriented downstream from the supply reel;a severing device oriented downstream from the clamping apparatus, wherein the severing device is configured to sever a section of the film tape, the severed section defining a severed film strip;a transfer apparatus oriented downstream from the severing device, wherein the transfer apparatus is configured to transfer the severed film strip to the spacer such that a first portion engages the first spacer leg and a second strip portion protrudes over the corner joint;a pressure apparatus operable to press the first portion of the severed film strip against the first leg of the spacer; anda pressure carriage movable along a plurality of axes, wherein the pressure carriage presses a second portion of the severed film strip against the second leg of the spacer,wherein the pressure carriage moves independently of the transfer apparatus. 19.
