A method performed and apparatus formed to fabricate an Isofix latch wire arrangement bends an elongated strip about an open profile to form an elongated tubular member, radially penetrating the member with wires across the open profile, and forming enlarged portions on the legs. The enlargements engage opposite sides of the tube to complete abutment of the strip edges to close the profile and join the wires as rivets to the tubular member formed.

The present invention provides for a tubular member having a sidewall. The sidewall is arranged in a tubular configuration where an attachment lip and an attachment overlap are substantially aligned. A seal is formed between the attachment lip using an adhesive, and elastically loaded arm, and/or a mechanical fastener instead of a weld to form a closed, tubular member.

The leading end portion of a caulking pawl portion formed in the end portion of a pipe main body is formed integrally with the pipe main body through the side surface portion of the caulking pawl portion which has a larger width in the longitudinal direction thereof than the width of the leading end portion in the longitudinal direction thereof. At the same time, the leading end portion of the caulking pawl portion is also formed integrally with the cap side end of the side surface portion of the caulking pawl portion.

A method for assembling sheet metal pipes, and a machine for carrying out the method which comprises assembling a pipe from a preformed pipe blank into a finished pipe without permanently deforming the pipe blank material. The method comprises the steps of folding of a preformed pipe blank, having a male lock joint member along one longitudinal edge and a female lock joint member along the other longitudinal edge so as to move the longitudinal edges toward each other, and then inserting the male lock joint member into the female lock joint member, with the spring tension created in the pipe blank due to the folding action effecting a locking action between the two lock joint members. The pipe snapper machine includes a pair of idler rollers and a pair of drive rollers aligned with the idler rollers for receiving a leading end of a pipe blank and moving the male lock joint member along one longitudinal edge of the blank form into a female lock joint member along the adjacent longitudinal edge of the pipe blank into locking engagement. The machine includes an entrance pipe guide and an exit pipe guide is provided. A power source is provided for driving the drive rollers. The idler rollers effect a vertical pressure on the pipe blank as it is passed therebetween. The drive rollers effect a transverse assembly pressure on the pipe blank as it is passed therebetween.
