Abstract

1399746 Making tennis balls DUNLOP Ltd 29 June 1973 [1 July 1972] 30923/72 Heading A6D [Also in Division B5] Two parts of a hollow rubber core of a tennis ball are adhesively joined by applying adhesive to at least one of the parts, fitting the parts in a joining tube and pressing the parts together while gripped by radially inwardly projecting, axially oriented ribs or splines on the internal surface of the tube. The parts may be pressed together manually or by plungers. In one embodiment, Figs. 2 and 3, the tube 10 comprises fifteen internal axial projections 11 and grooves 12 with no pair of projections being diametrically opposed. The tube has flared ends 15 to facilitate entry of the parts. The grooves 12 have plain walls 13 and the' projections 11 shaped walls 14. Each wall 14 has an annular groove 18 defining the joining position and located in a central projecting portion 17 between plain portions 16. In another embodiment, Figs. 6 and 7, the projections. 21 are part of a separate insert 23 and are shaped as shown in Fig. 6. The grooves are shaped as shown in Fig. 7. The insert 23 has two external circumferential grooves 26, 27 carrying circlips 28, 29 to spring-load the insert [GB1399746A]
