ABSTRACT:
A method is disclosed for clamping together a first and a second part, the first part having a flange thereon, the second part having a groove which may receive the flange. The method includes the steps of placing a deformable seal on the bottom of the groove of the second part, placing the flange of the first part on the deformable seal as the flange is guided into the groove, clamping the first and second parts together while deforming the seal until the seal approximately fills a space defined between a lower surface of the flange and the walls forming the groove, and deforming certain parts of a vertically upright standing area of the second part by rolling the certain parts of the area over an upper surface of the flange into generally horizontal positions while leaving other parts of the area generally in their vertically upright condition to thereby form an approximately corrugated edge on the second part, which holds the first and second parts together in a clamped condition. A device for establishing a clamping connection in this manner is also disclosed.
