A tubular element, for coalescing water from fuel or filtering solids from liquid, is made by rolling a batt 18 of glass fibre spirally, incorporating in the end faces strips 56 of thermoplastic and bonding the roled 'batt to thermoplastac end caps (Fig. 1, not shown) by 'spin welding', in which strips and caps are melted by friction therebetween and then held together. The caps bond to both the strips 56 and the glass fibre. In Fig. 4, strips 56 are folded round the edges of a glass fibre screen 50 which is then rolled to form the outer layer of the roll. Alternatively an extruded strip of U-section (Fig. 6, not shown) or a single strip heat-bonded to screen 50 may be used. If no screen 50 is used (Figs. 1 to 3, not shown), the thermoplastic strips (22) may be laid along the edges of batt 18 before rolling and themselves extend several times round the element. Additional porous supports may be included inside and outside the roll.,下面是Elements for removing contaminants from liquid专利的具体信息内容。
