Abstract
Abstract A device for mounting flexible spacers (22) to glass sheets during the course of manufacturing insulating glass comprises a processing tool (4) movable along the periphery of a glass sheet held in the device, the tool mounting the spacer (22) to the glass sheet with the aid of a pivotable sliding pressure pad (21). Devices (34, 35, 36, 37) with angles are provided for shaping the corner zones of the spacer (22) mounted to the glass sheet, and a clamp (51) for joining the ends of the spacer (22) to each other.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A device for mounting elongated flexible spacers for insulating glass on a glass sheet, comprising a vertical beam, means mounting the beam for horizontal movement along a glass sheet to which an elongated flexible spacer is to be applied, a slide movable vertically on the beam, a storage reel for a rolled up length of said spacer, a feeding roller pair between which said spacer moves upon leaving the storage reel, a pressure pad for pressing said spacer against a glass sheet, means mounting the feeding roller pair and the pressure pad on the slide for vertical swinging movement about an axis perpendicular to the glass sheet, and severing means carried by the slide for cutting off an applied length of the spacer.
Claim 2
Independent Claim
123 words
A device for mounting elongated flexible spacers for insulating glass on a glass sheet, comprising a vertical beam, means mounting the beam for horizontal movement along a glass sheet to which an elongated flexible spacer is to be applied, a slide movable vertically on the beam, a storage reel for a rolled up length of said spacer, a feeding roller pair between which said spacer moves upon leaving the storage reel, a pressure pad for pressing said spacer against a glass sheet, means mounting the feeding roller pair and the pressure pad on the slide for vertical swinging movement about an axis perpendicular to the glass sheet, and severing means carried by the slide for cutting off an applied length of the spacer.
Claim 3
Dependent Claim
44 words
Device according to claim 1, the severing means comprising a blade, and a guide disposed on the opposite side of the path of the spacer from the blade and serving as an abutment against which the spacer is pressed by the blade during severing.
Claim 4
Dependent Claim
48 words
Device according to claim 1, said pressure pad having two guide strips thereon with said roller pair disposed at an entry end of said two guide strips for entry of the spacer between the two guide strips, said axis being at the outlet end of said guide strips.
Claim 5
Dependent Claim
29 words
Device according to claim 1, and means for shaping square corners of the spacer, there being a said shaping means in each of four corners of the glass sheet.
Claim 6
Dependent Claim
22 words
Device according to claim 4, said corner shaping means being mounted on slides that are adjustable upward and downward along guide rails.
Claim 7
Dependent Claim
33 words
Device according to claim 4, each said corner shaping means comprising two angles which, for forming the corners of the spacer, can be moved toward each other against opposite sides of the spacer.
Claim 8
Dependent Claim
16 words
Device according to claim 6, said angles being mounted on piston rods of pressure medium motors.
Claim 9
Dependent Claim
38 words
Device according to claim 7, said pressure medium motors being mounted on a supporting plate which in turn is mounted for reciprocatory movement by means of a further pressure medium transversely to the plane of the glass sheet.
