Summary of the wire drawing machine According to the present invention, a drum for a multiple wire drawing machine is provided comprising an arrangement of at least two adjacently located capstans operatively connected to each other at least one of which is driven by a central drive shaft. Each of the capstans comprises an annular drawing machine and a wheel member located within the drawing ring, and connected thereto for conjoint rotation. At least the one driven capstan has a planet member engaging the associated wheel member, and an annular sun member secured to the shaft. Further, a seal is interposed between the capstan assemblies which preferably seats on the wheel member of one of the capstan assemblies and on a sliding surface of the wheel member or drawing ring of the other capstan assembly. Amongst the objects and advantages of the present invention is achievement of a drawing drum wherein each capstan forms an interchangeable structural unit, of which the rod breakown machine ring may be a part of an internally toothed or flanged hollow wheel which is rotatably mounted about a sun wheel and which carries a planet member, which rolls on the sun wheel and which simultaneously, to effect the differential transmission, produces the operative connection to the adjacent structural unit. It is also advantageous to reduce expense and noise to use transmission elements (e.g., friction rollers and the like) to serve for the transmission of the force. A wire drawing machine which does not require much maintenance can be produced by using elements which consist wholly or almost completely of resilient wear-resistant material (e.g., of polyamide or polyurethane). With a view to a further reduction of maintenance and of saving constructional parts, it is possible to mount the planet member in an overhung or cantilevered arrangement on the supporting shaft. However, in order to provide a more fine wire drawing machine, it is advantageous for the supporting shaft of the member to be supported at both its ends. Full details of the present invention are set forth in the following disclosure and are shown in the accompanying drawings.
