摘要： The invention relates to a method for making tubes formed with holes in their peripheral wall, particularly muffler tubes, in which the tubes are formed of sheet metal and subsequently welded along abutting edges of the sheet metal. Known from practical application is a method of the type defined above, in which a hole pattern is initially punched into a sheet metal strip. The metal strip is subsequently formed, as by a roll forming method, into tubes which are then closed by a longitudinal weld seam. After the welding step the tubes are cut to length by means of a cutting device, the operation of which is controlled depending on the hole pattern. It is the object of an invention to provide a method and apparatus of the type defined above which in addition to the advantage of economical production offers the possibility of forming the tubes with holes over their entire periphery. With regard to the method according to the invention, this object is attained by introducing a backing element into the previously welded tube and forcing it into engagement with the interior wall surface thereof, followed by the formation of holes from the exterior in the area of the tube supported by the backing element.
摘要翻译：本发明涉及一种用于制造在其周壁上形成有孔的管子，特别是消声器管，其中管由金属板形成并随后沿着金属片的邻接边缘焊接。实际应用中已知的是上述类型的方法，其中孔图案最初被冲压成金属板条。随后，通过辊压成型方法将金属条形成为管，然后由纵向焊缝封闭。在焊接步骤之后，通过切割装置将管切割成长度，其操作根据孔图案来控制。发明内容本发明的目的是提供一种上述类型的方法和装置，除了经济生产的优点外，还提供了在其整个周边上形成具有孔的管的可能性。关于根据本发明的方法，该目的通过将背衬元件引入先前焊接的管并且迫使其与其内壁表面接合，然后在外部的区域中形成孔管由支撑元件支撑。

摘要： A method of making a multi-layer tube includes the steps of pre-heating two elongate metal strips and bending each to a substantially arcuate curvature. Each strip is then wound helically with abutting edges, one strip being closely concentrically wound around and axially offset with respect to the other, so that the strips define a cylindrical tube. A synthetic resin is applied between the strips and to the interior of the tube during the winding step and is then pre-cured. Thereafter, a coating of the synthetic resin is applied to the exterior of the tube and then all of the synthetic resin is fully cured.
