<p>A joined plate and tube includes a plate (12) with an annular neck (13), and a tube (11) extending through the annular neck and including a first reversing fold (14) around a peripheral end of the annular neck, and a second reversing fold (15), such that at least part of the annular neck (13) is held within a substantially S-shaped folded portion (16) of the tube (11). A method of joining a tube (11) to a plate (12) includes providing a tube (11) having a radially outwardly-extending annular portion (27), providing a plate (12) having an annular neck (13) extending therefrom, positioning the tube such that it extends through the annular neck and the annular neck (13) abuts the annular portion (27), and folding the annular portion (27)over the annular neck (13) to hold at least part of the annular neck in a substantially S-shaped portion of the tube.</p> |
