Abstract
A method of adhesively joining two elements by an adhesive layer without gas inclusion in the adhesive layer, wherein an adhesive layer is applied over an area of a surface of a first of the two elements and channels are provided in the adhesive layer for passage of gases therein. An opening around the area of the adhesive layer is in communication with the channels to form a gas escape system so that when the elements are joined together the gases can escape from the adhesive layer via the channels and the opening.
Claims21
A method of adhesively joining two elements by an adhesive layer without gas inclusion in the adhesive layer, said method comprising:
- applying an adhesive layer over an area of a surface of a first of two elements to be joined together,
- providing channels in said adhesive layer for passage of gases therein,
- providing an opening around said area of said adhesive layer in communication with said channels to form a gas escape system therewith, and
- contacting the surface of the first of the two elements with a complementary surface of a second of the two elements at said adhesive layer to adhesively join the two elements together while permitting gases to escape from the adhesive layer via said channels and said opening thereby preventing inclusion of gases in said adhesive layer.
A method of adhesively joining two elements by an adhesive layer without gas inclusion in the adhesive layer, said method comprising:
- applying an adhesive layer over an area of a surface of one element to be joined to a complementary surface of a second element, and
- forming a gas passage means in said adhesive layer for escape of gases from the adhesive layer when bringing said surfaces of the two elements into contact with one another whereby to prevent gas inclusion in said adhesive layer after joining the two elements together.
