A method of producing a low-weight hollow-cylindrical body, preferably a printing cylinder or drum for a silk-screen printing machine operating at high speeds. By placing a number of units having preferably the form of frusto-circle sectors in side-by-side relationship and joining said units together it is possible to form the cylindrical surface of said drum. Each unit is produced by extrusion techniques; and each unit is joined to the adjacent unit by glue or the like; each unit is provided with at least one space and wherein said space is arranged to communicate with a vacuum generating means via holes disposed in at least one wall defining said space. The invention includes a hollow-cylindrical body produced by the method. |
