Abstract

PURPOSE:To simplify the sealing by heating the leading end of a hot melt sealing material, coating and filling the four circumferential sides of a pair glass with the sealing material which keeping an uncured state, and jointing smoothly the terminal end with the leading end. CONSTITUTION:A pair glass 2 is formed by opposing a pair of glass plates 1 to each other through a spacer 4 made of Al, etc., and a recessed groove 5 to be filled with a hot melt sealing material 3 is provided to the cirvumference between the glass plates 1. The leading end 3a of the sealing material 3 to start the filling is pintched from the upper part of the glass plates 1 with a clip 6 furnished with a heater, and the sealing material 3 is successively filled into the four circumferential sides of the pair glass 2 while heating the leading end 3a and keeping the sealing material 3 in an uncured state. When the four sides are completely filled, the terminal end 3b is bonded to the uncured leading end 3a. The leading end 3a is satisfactorily bonded and combined to the terminal end 3b in this way, and the completely sealed pair glass can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing double glass used for windows of houses and the like.

[Background technology]

Conventionally, when filling the periphery of the pair glass (2) with the hot melt sealant (3), the hot melt sealant (3) is continuously filled around the periphery of the pair glass (2) starting from the starting end (8a), Go around the application, return to the beginning, and apply at the end (8
When bonding b) to the starting end (8a) and splicing, the temperature of the starting end (8a) has already decreased and hardening has progressed,
Good adhesion between the starting end (8a) and the ending end (8b) could not be obtained. Therefore, hot melt sealing material (3) is used around the four circumferences.
After coating, the starting end (8a) was heated again to soften it again, and the spliced part was recast.

[Purpose of the invention]

The present invention was made in view of the shortcomings of conventional vehicle collection systems, and its purpose is to heat the starting end of the hot melt sealant and apply it to all four circumferences while maintaining an uncured state. This allows the terminal end to be bonded to the start end smoothly and jointed, thereby simplifying the sealing work.

[Disclosure of the Invention] The method for manufacturing double glass of the present invention comprises a pair of glass plates (1).
When continuously filling the four circumferences of the pair of glass glasses (2) with the hot melt sealant (3), the starting end (8a) of the hot melt sealant (3) at the beginning of filling is heated to bring it into an uncured state. The hot melt sealant (3) is continuously filled around the periphery of the double glass (2) while maintaining the temperature, and the terminal end (8b) of the filling wire is adhered to the starting end (8a) to form the starting end ( 8a) and the terminal end (8b) are continuous, thereby achieving the above object.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. (2) is a pair of glass plates (
This is a pair of glasses with glass plates (1) facing each other, and a groove (5) for filling a hot-melt sealant (3) is provided around the space between the glass plates (1). First, a pair of crows (2
), start filling the hot-melt sealing material (3) such as hot-melt butyl rubber, and insert the starting end (8a) from above the glass plate (1) into the electric seal-9 built-in as shown in Figure 8. Hold it in place with the clips (6) and heat the starting end (3a) with the clip (6) with the insulator, keeping it in an uncured state, continuously around the four circumferences of the pair of crows (2). The hot-melt sealing material (3) is filled, and after one round, the terminal end (8b) is adhered to the uncured starting end (8a).

As a result, the starting end (8a) and the ending end (3b) are well bonded and form a single line, making it possible to perform the sealing operation easily and to perform the sealing completely.

〔Effect of the invention〕

Since the present invention uses a gutter bottom as described above, after the hot melt sealant is filled around the pair of crows, the terminal end can be well bonded to the starting end without reheating the starting end. This has the advantage of making sealing work easier and reliably sealing the gaps between glass plates.

Claims (1)

[Claims] (1) When continuously filling the four circumferences of the paired crow with a pair of glass plates facing each other with hot melt sealant, the starting end of the hot melt sealing material at the beginning of filling is heated to maintain an uncured state while the glass is heated. 1. A method for manufacturing double glass, comprising: continuously filling the periphery of the glass with a hot-melt sealing material; and bonding the terminal end of the filling path to the starting end, thereby making the starting end and the terminal end continuous.
