Abstract
For the emplacement of spacer shims (21) on glass panes, especially insulating glass panes, an apparatus is disclosed with a storage reel for a strip (2) of cork or the like covered on one side with an adhesive coating, with a drive mechanism for the stepwise conveyance of the strip (2) to a cutting unit (20), with a pressure applicator, provided following the cutting unit (20) for spacer shims (21) cut to size from the strip (2). The suction cup (40) of the pressure-applying means can be advanced toward the surface (44) of a glass pane facing this suction cup and is furthermore freely movable in parallel to the conveying direction (45) of a glass pane to which spacer shims (21) are to be applied. Thus, spacer shims (21) can be attached to glass panes even during movement of the latter.
Claims10
In apparatus for emplacing spacer shims (21) on glass panes, comprising a storage reel for a strip (2) of spacing material covered on one side with an adhesive coating, this coating being covered by a protective film (3);
- a drive mechanism for conveying the strip (2) to a cutting unit (20);
- a pressure-applying means provided following the cutting unit (20) for the spacer shims (21), cut to size from the strip (2) by means of the cutting unit (20), the pressure-applying means (40, 41) comprising a suction cup (40) for seizing the spacer shims (21), arranged in an initial position (I) on a delivery side of the cutting unit (20), and means to advance said suction cup toward a surface (44) of a glass pane that faces said suction cup and to which a spacer shim (21) is to be attached;
- the improvement wherein the last-named means comprises a piston rod (41) of a pressure medium cylinder (42) pivotably (axis 43) mounted on the apparatus and oriented perpendicularly to said surface.
In apparatus for emplacing spacer shims (21) on glass panes, comprising a storage reel for a strip (2) of spacing material covered on one side with an adhesive coating, this coating being covered by a protective film (3);
- a drive mechanism for conveying the strip (2) to a cutting unit (20);
- a pressure-applying means provided following the cutting unit (20) for the spacer shims (21), cut to size from the strip (2) by means of the cutting unit (20), the pressure-applying means (40, 41) comprising a suction cup (40) for seizing the spacer shims (21), arranged in an initial position (I) on a delivery side of the cutting unit (20), and means to advance said suction cup toward a surface (44) of a glass pane that faces said suction cup and to which a spacer shim (21) is to be attached;
- the improvement wherein the cutting unit (20) includes a hollow cylinder (22) comprising two openings (23 and 24) in substantially diametrical mutual opposition for the entrance and, respectively, exit of the strip (2), and a partly cylindrical cutting blade (25) in the interior of the hollow cylinder (22) and rotatable relative to the cylinder.
