Abstract:
A window or door glazing has a stepped pane element (3) which is adhesively bonded all the way around to a frame (10), for example the frame (10) of a window sash. In this case, two regions of adhesive compound are provided, firstly in the region of the smaller pane (2) of the stepped pane element (3), and secondly on the inside of the protruding edge of the larger glass pane (1) of the stepped pane element (3).
Abstract:
A glass breaking table includes two rows of suction pads, on either side of a gap between table platforms. A breaking strip in the gap can be raised. A pressure tool including two fingers is provided above one end of the gap. A glass sheet is held on either side of the gap by negative pressure to the suction pads and is pre-tensioned in a convex manner, (the convex face of the sheet having a scored line), with the aid of the breaking strip, which can be raised uniformly along the entire length of the glass sheet in the vicinity of the scored line. The pressure tool exerts a pressure from above only in the vicinity of one end of the scored line in the edge region of the sheet on both sides of the scored line, initiating the breaking of the pre-tensioned glass sheet along the scored line.
Abstract:
In order to seal the corner joint of an elastoplastic tape placed as a spacer on a glass pane, a film strip is pressed with a first portion of its length against the first leg section of the spacer and the protruding portion of the film strip is wrapped around the corner and pressed against the second leg section. For the purpose of automating this process, the film strip is severed mechanically from an automatically supplied film tape and held via a transfer apparatus which thereafter presses the film strip with the first portion of its length against the first leg section. The portion of the film strip protruding freely over the corner is wrapped around the corner via a pressure carriage and pressed by tautening against the second leg section of the spacer.
Abstract:
A device for the dimensionally accurate application of an elastoplastic spacer strip onto a glass pane is disclosed. The device includes a compensating or tailback section between a first adjustably driven pair of rollers and a second adjustably driven pair of rollers, as well as a sensor for recognizing the position of the strip in the compensating section. The device is designed such that the spacer strip is not withdrawn from the storage drum but, instead, is unwound in a manner free from any tensile stress. The spacer strip, furthermore, is kept free from tensile and shearing stresses on the route up to being pressed onto a glass pane, despite the fact that the application speed will inevitably fluctuate several times between zero and a maximum value while edges of the glass pane are covered mechanically.
Abstract:
A blade is used to cut through a film between the panes of laminated glass in the area of a gap produced in the laminated glass the blade is provided on a holding device and can move along the gap. The holding device includes swiveling carrier on which there is a holding part for the blade with a vertical adjustment capacity. The blade is first placed next to the gap on the top of the top pane of the laminated glass. The vertical alignment of the blade is ascertained with a rule for determining the thickness of the laminated glass. Then the holding device is adjusted by a motor such that the blade falls into the gap. When a sufficient immersion depth of the blade into the gap is ascertained via the rule, the film is cut.
Abstract:
When a thermoplastic spacer is applied to a glass pane in the production of insulating glass panes, the nozzle from which the plastic with the desired cross sectional shape is extruded along the edge of the glass pane. The speed with which the plastic is applied along the edge of the glass pane is chosen depending on the temperature of the plastic. Here, for a stipulated temperature setpoint the speed with which the plastic is applied along the edge of the glass pane is stipulated. If the temperature increases, the speed is increased; conversely, when the temperature drops below the setpoint, the speed with which the plastic is applied along the edge of the glass pane is reduced. This ensures that the correct amount of thermoplastic is always extruded onto the glass pane and a spacer with a uniform cross section is obtained.
Abstract:
A device for edging of glass panes (3) has at least one grinding head as the machining tool, consisting of two crossing belt grinders (10, 12) which simultaneously engage the edges of one border of the glass pane (3) to edge-finish these edges. The belt grinders (10, 12) are supported to swivel in the machine frame (1) so that from a readiness position into their [sic] they can be placed against the edges of one border of the glass pane (3) which is to be edged for example to remove burrs. Because the belt grinders (10, 12) are arranged to be adjustable, their position can be matched to glass panes (3) of varied thickness. When there are several grinding heads, glass panes (3) can be machined at the same time on several borders.
Abstract:
When sealing an insulating glass pane (51) with at least one corner in which the edges (60) of the glass panes of the insulating glass pane (51), i.e. the edges which lead to the corner, include with one another an angle, for example a right, obtuse or acute angle, the sealing nozzle (4) is moved without stopping in one pass around the corner (61) and as the sealing nozzle (4) moves around the corner the emergence of the sealing mass from the sealing nozzle (4) into the edge joint is not interrupted. When travelling around one corner (61) the path (79) of movement of the axis which is aligned perpendicular to the plane of the insulating glass pane (51) to be sealed and around which the sealing nozzle (4) can turn is guided such that it deviates from the outside contour of the insulating glass pane (51). For sealing nozzles (4) which are guided to slide externally along the edges (60) of the glass panes of the insulating glass pane (51), i.e. the edges which border the edge joint, the path (79) of movement is selected such that in the area of corner (61) it runs away from the outside contour of the insulating glass pane (51) to the outside and following corner (61) back again to the edge of the insulating glass pane (51). In the sealing nozzles which dip into the edge joint to be sealed, the path of the axis is chosen such that it deviates in the area of the corner (61) from the outside contour of the insulating glass pane (51) to the inside in the shape of an arc.
Abstract:
A system for tempering glass plates has preheating zone (1) in which several glass plates (7) stacked vertically in compartmented car (6) are heated together to a temperature below the tempering temperature of for example 650.degree. C. (for example 300.degree. C.). Preheated glass plates (7) are moved individually from preheating zone (1) into heating zone (2). In heating zone (2) glass plates (7) are heated to the tempering temperature, their being inclined to the vertical at an acute angle and being held by air cushions between two heating plates. On the lower edge of the two heating plates of heating zone (2) there is transport device which supports glass plates (7) simultaneously to the bottom. Glass plates (7) heated to the tempering temperature are moved into cooling zone (3) which has cooling plates aligned parallel to the heating plates and between which glass plate (7) is pushed for quenching. The cooling plates can also be placed on the two sides of glass plate (7) to be tempered for purposes of quenching. The quenched glass plates which still have a temperature of for example 300.degree. C., are transported into after-cooling zone (4) in which they are slowly cooled to room temperature after being deposited in compartmented cars (6).Because glass plates (7) are placed in heating zone (2) and cooling zone (3) obliquely, not horizontally, there are no problems with support and transport of glass plates (7). Joint preheating of glass plates (7) and joint cooling of glass plates (7) to room temperature after quenching thereof save considerable energy since the heating and cooling power in preheating zone (1) and aftercooling zone (4) can be low.
Abstract:
Belt brush (30) which engages the bottom of glass plate (10) to remove lubricant or other impurities is assigned to edge (24) of glass cutting table (20), the edge which is forward relative to the conveyor direction (arrow 11), in which table there are several conveyor belts (25) which transport glass plate (10) to be cut. Upper strand (37) of continuous brush belt (35) of belt brush (30), the strand which engages the bottom of glass plate (10), removes lubricant from the bottom of the glass plate so that the lubricant can be captured and disposed of on one end of belt brush (30) in tank (50) which can be pressurized with negative pressure.
