Spacer on a device for connecting two glass plates to form an edge-bonded insulating-glass pane

A spacer on a device for connecting two glass plates to form an edge-bonded insulating-glass pane by arranging the two glass plates spaced apart in parallel relationship so as to form a gap therebetween, injecting a strand of initially pasty and subsequently solidifying adhesive material adhering to the two glass plates, over the entire periphery along the pane edge into the gap between the two glass plates which glass plates are supported via at least one of their large faces and held at a distance from one another so as to be congruent with and parallel to one another, the device for connecting two glass plates comprising a horizontal conveyor for the two glass plates held at a distance from one another, which conveyor defines a pane running plane constant for one of the two glass plates and on which conveyor is arranged at least one nozzle which penetrates into the gap between the two glass plates and to which nozzle the spacer penetrating into the gap between the two glass plates is assigned at a constant distance relative to said nozzle and in advance in relation to the movement of the nozzle relative to the two glass plates, the spacer being defined in that it has two rollers which are arranged next to one another with axes of rotation extending parallel to one another and to the pane running plane and at right angles to a predetermined direction of the relative movement between the nozzle and the glass plates and of which rollers one is intended to rest against the inner surface of one glass plate and the other is intended to rest against the inner surface of the other glass plate.
