Patent ID: 8622110

Claim:
An apparatus for sealing a corner joint of an elastoplastic tape placed on a glass pane as a spacer, the spacer including a first leg and a second leg connected along the corner joint, the apparatus comprising: a supply reel for holding a film tape including adhesive on one side; a controlled tape drive for withdrawing the film tape from the supply reel; a clamping apparatus for securing an end section of the film tape, the clamping apparatus comprising a jaw with bores for sucking the film tape towards a contact surface, wherein the jaw is displaceable substantially synchronously with the tape drive in a tape transport direction; a severing device for severing an end section of the film tape to form a severed film strip; a transfer apparatus to transfer the severed film strip to the spacer, the transfer apparatus comprising: a contact surface with bores for sucking the film strip before and after severing from the film tape, a first drive which advances the transfer apparatus in a tape transport direction to position the film strip proximate the spacer corner joint, and a second drive configured to press the transfer apparatus into engagement with the spacer, transferring the severed film strip to first spacer leg such that a first portion of the severed film strip is adhered to the first leg and a second portion protrudes over the spacer corner joint; and a pressure carriage configured to be lowered vertically on the second leg of the spacer and subsequently displaced horizontally via drives for wrapping the second portion of the severed film strip protruding over the corner joint and for pressing the wrapped the protruding portion of the severed film strip against the second leg, wherein the clamping apparatus and the transfer apparatus cooperate to hold the end section of the film tape while the film tape is being severed.
