   Um eine glatte   Oberflache   der äusseren   Tuchhülle   und einen weichen Aufschlag zu erzielen sowie das Gewicht des Balles variieren zu können, wird über den Innenball a eine elastische oder plastische Zwischenschichte b aus gelatinöser Masse aufgebracht, welche die Wellentäler der Luftseele ausgleichen soll. 



   Über diese plastische Zwischenschichte b wird die äussere Tuchhülle c in bekannter Weise gelegt.

  Tennis ball.
 EMI1.1
 Manufacture the inner ball of tennis balls and the like from thin sheet metal or prepared intestinal skin, expediently in such a way that this inner ball has a corrugated outer surface to enable it to be compressed and expanded, as shown in FIG. 1 in cross section and FIG. 2 in the view , where a denotes the corrugated inner sphere.



   In order to achieve a smooth surface of the outer cloth cover and a soft serve as well as to be able to vary the weight of the ball, an elastic or plastic intermediate layer b of gelatinous material is applied over the inner ball a, which is supposed to compensate for the corrugation of the air core.



   The outer cloth cover c is placed over this plastic intermediate layer b in a known manner.



   The production of a ball with a corrugated surface from prepared intestinal skin takes place in two hollow ball halves of the gelatinous mass and by subsequent assembly
