In order to produce sharp corners in edge regions (2) of a strand (1) of deformable material which is applied to a glass pane, the strand (1) forming a spacer in the insulating glass, a tool (5) is forced against the outer corner (3) and a tool (6) against the inner corner (4). The tools (5, 6) have active portions (7, 8) which correspond to the shape of the outer corner (3) and to the shape of the inner corner (4).

1. A method for forming at least one corner in a spacer for insulating glass, the spacer being a strand (1) of deformable material applied to the glass pane, comprising: placing a first tool (5) on an outside of the strand (1) in an area (2) of a corner portion thereof;placing a second tool (6) on a
1. A method for forming at least one corner in a spacer for insulating glass, the spacer being a strand (1) of deformable material applied to the glass pane, comprising: placing a first tool (5) on an outside of the strand (1) in an area (2) of a corner portion thereof;placing a second tool (6) on an inside of the strand (1) in the area (2) of the corner portion;moving said first and second tools (5, 6) to exert pressure on lateral surfaces of the strand (1) at the corner portion of the strand (1) for forming the corner portion of the strand (1) into a corner shape with outer and inner corners (3, 4), said lateral surfaces being essentially perpendicular to a surface of the glass pane, the outer and inner corners (3, 4) of the strand (1) formed by the first and second tools (5, 6) corresponding to respective shapes of the first and second tools (5, 6);simultaneous with the forming of the outer and inner corners of the strand (1) with the moving of the first and second tools (5, 6), exerting a pressure using a hold-down element (18) upon an opposing surface of the strand (1) at the area of the corner portion and facing away from the glass pane, said hold-down element (18) having an effective surface oriented essentially parallel to the opposing surface for contact with the opposing surface,wherein the outer and inner corners are formed on the strand (1) by the first and second tools (5, 6) in situ on the surface of the glass pane,wherein the first tool (5) has effective surfaces (7) that correspond to a negative shape of the outer corner (3) of the strand (1) to be formed by the first tool (5), the first tool (5) having two effective surfaces (7), at an angle to one another, for shaping the outer corner (3)wherein the second tool (6) has effective surfaces (8) that correspond to a negative shape of the inner corner (4) of the strand (1) to be formed by the second tool (6), the second tool (6) having two effective surfaces (8), at an angle to one another, for shaping the inner corner (4),wherein the first tool (5) and the second tool (6) are placed on the strand (1) simultaneously, andwherein the hold-down element (18) forms a recess in the opposing surface of the strand (1) simultaneously with the forming of the outer and inner corners of the strand (1) with the moving of the first and second tools (5, 6). 2. The method according to claim 1, wherein the first and second tools (5, 6) are pressing bodies for forming the corners. 3. The method according to claim 2, wherein any of the first tool and the second tool (5, 6) is arranged on a nozzle that applies the strand on the glass pane. 4. The method according to claim 1, wherein any of the first tool and the second tool is arranged on a nozzle that applies the strand on the glass pane. 5. The method according to claim 1, wherein the outer and inner corners (3, 4) of the strand (1) are formed by the first and second tools (5, 6) before the strand (1) is adhesively connected to the glass pane. 6. The method according to claim 1, wherein an instance of said first tool (5) and said second tool (6) is placed at each corner of the glass plane, and each corner of the glass plane are brought into a corner shape simultaneously. 7. The method according to claim 1, wherein the angle of the effective surfaces of at least one of said first tool (5) and said second tool (6) is changeable. 8. The method according to claim 1, wherein the first and second tools (5, 6) operate to slide across the surface of the glass pane. 9. The method according to claim 1, wherein the first and second tools (5, 6) comprise a material that is anti-adhesive relative to the material of the strand (1). 10. The method according to claim 1 wherein, prior to the exerting of pressure on the lateral surfaces of the strand (1), the first and second tools (5, 6) are heated. 11. The method according to claim 1 wherein the effective surfaces (8) of the second tool (6) are joined by a transition surface (9) that is intermediary between said effective surfaces (8).
