ABSTRACT:
A process and apparatus for the covering of playing balls, in particular tennis balls, utilize two essentially dumbbell-shaped cover parts and apply the parts interlockingly at an angle of 90.degree., successively to the adhesive coated ball core by rolling over the laid out, dumbbell-shaped cover parts. The cover parts are stacked to form a magazine and are provided with a layer of an adhesive so that only their peripheral surfaces are coated. The adhesive coated ball cores are rolled successively, initially by means of a contact pressure device in the longitudinal direction over a first cover part magazine and subsequently by means of a second contact pressure device and second cover part magazine extending transversely to the longitudinal direction of the first cover part magazine. The edge of the second cover part engages the bight of the cover part already in position at a decorative seam gap.
