The apparatus serves to apply a plastic strip to a rectangular glass pane so that the strip extends peripherally along all edges of the pane. The apparatus comprises conveying means for conveying the glass panes, which conveying means comprise a horizontal conveyor for supporting and conveying the glass panes standing on their lower edge, backing means, which extend above the horizontal conveyor and are adapted to laterally support the glass panes standing on the horizontal conveyor in a predetermined plane of conveyance, which is slightly inclined from the vertical toward said backing means, pressure-applying means, which are slightly spaced above the horizontal conveyor and serve to force the plastic strip against a moving glass pane, a strip feeder, which is operable to move in synchronism with the horizontal conveyor at the same speed as the latter to feed the plastic strip to the pressure-applying means, a turning mechanism, which when the horizontal conveyor is at a standstill is adapted to turn each glass pane through 90° opposite to the normal direction of travel of the horizontal conveyor, strip-guiding means for cooperating with the pressure-applying device, and severing means for severing the plastic strip.

1. Apparatus for applying to a glass pane a plastic strip, which is adhesive on two mutually opposite, parallel side faces and comprises a plastic material, a moisture-absorbing substance and a metal strip that extends between said two side faces and in the longitudinal direction of the plastic strip, which plastic strip is applied to said glass pane to extend continuously along the periphery of said glass pane at a predetermined distance from the edge of said pane, characterized in that said apparatus comprises conveying means for conveying the glass panes, which conveying means comprise a horizontal conveyor for supporting and conveying the glass panes standing on their lower edge, backing means, which extend above the horizontal conveyor and are adapted to laterally support the glass panes standing on the horizontal conveyor in a predetermined plane of conveyance, which is slightly inclined from the vertical toward said backing means, pressure-applying means, which are slightly spaced above the horizontal conveyor and serve to force the plastic strip against a moving glass pane which is in contact with one adhesive side face of the plastic strip, a strip feeder, which is operable to move in synchronism with the horizontal conveyor at the same speed as the latter to feed the plastic strip to the pressure-applying means, a turning mechanism, which when the horizontal conveyor is at a standstill is adapted to turn each glass pane through 90° opposite to the normal direction of travel of the horizontal conveyor about an axis which is spaced slightly above the pane-supporting plane of the horizontal conveyor and extends at right angles to said plane of conveyance, strip-guiding means, which are disposed adjacent to and cooperate with the pressure-applying means and are arranged to act on the top of the plastic strip at least during the turning operation, and severing means for severing strip sections in the required length from a plastic strip supply. 2. Apparatus according to claim 1, characterized in that the pivotal axis of the turning mechanism is disposed on the level of the pressure-applying means. 3. Apparatus according to claim 1, characterized in that the strip-guiding means for acting on the top of the plastic strip comprise a roller which is small in diameter and has an axis of rotation that is at right angles to said plane of conveyance. 4. Apparatus according to claim 3, characterized in that the axis of rotation of the roller coincides approximately with the pivotal axis of the turning mechanism. 5. Apparatus according to claim 3, characterized in that the axis of the roller is disposed slightly below and, when viewed in the direction of conveyance, slightly beyond the pivotal axis of the turning mechanism as the pane is turned. 6. Apparatus according to claim 1, characterized in that the turning mechanism comprises two pivoted arms, which extend at right angles to each other and are pivotally movable about their common pivotal axis while maintaining their orientation at right angles to each other and which arms are engageable with the glass pane at two edges thereof which are at right angles to each other. 7. Apparatus according to claim 2, characterized in that the strip-guiding means for acting on the top of the plastic strip comprise a roller which is small in diameter and has an axis of rotation that is at right angles to said plane of conveyance.
