Claims
- 1. A method of applying two cover pieces at right angles to one another around the surface of a resilient ball core, the method comprising placing cut-to-shape cover pieces flat in respective slots therefor in a planar loading plate, the slots having end portions which are generally of the shape of the cut cover pieces, moving the loading plate until a first of said slots lies in a position intermediate two enclosures on opposite sides of the loading plate, displacing said core from a position in the loading plate adjacent said first slot through said first slot into a first of said enclosures so that the cover piece in said first slot is carried with the core into said first enclosure and wrapped around the core, moving the loading plate until the second of said slots lies in said intermediate position between the enclosures and displacing the core from the first into the second of said enclosures through the second slot such that the cover piece in said second slot is wrapped around the core in perpendicular relation to the cover piece already wrapped thereon.
- 2. A method as claimed in claim 1, wherein the core is initially positioned in a first throughway in the loading plate in register with said first slot such that the core is supported by location means in said first throughway to lie within the loading plate, a first of said cover pieces is located in said first slot to overlie the core with an adhesive-coated surface of said cover piece presented to the core, a second of said cover pieces is located in said second slot with an adhesive-coated surface of said second cover piece presented oppositely to that of said first cover piece, said second slot being in register with a second throughway in the loading plate which is of greater diameter than the core throughout its length, and the loading plate is moved to bring said first and second slots and associated throughways in succession to said position intermediate the enclosures, the core being displaced from the first throughway into the first enclosure when in register therewith to carry said first cover piece into the first enclosure and wrap it around and adhere it to the core, thereafter the loading plate being moved to bring said second slot, throughway, and cover piece to said intermediate position while the core remains in the first enclosure, and then displacing the core with said first cover piece adhered thereto from the first enclosure through the second slot and throughway into the second enclosure to wrap the second cover piece around the core at right angles to the first piece and adhere the second cover piece to the core.
- 3. A method as claimed in claim 1, wherein consolidating members are moved inwardly of each enclosure behind the core when the latter has entered the enclosure to press the ends of the cover piece carried by the core into said enclosure into contact with the core, the consolidating members of the first enclosure serving to retain the core with the first core piece adhered thereto in the first enclosure during movement of the loading plate to bring the second slot to said intermediate position.
- 4. A method as claimed in claim 1, wherein the cover pieces are cut undersize relative to the slots in which they are to be located and wherein each cover piece after location in the respective slot is stretched to fill the slot, thereby assuming a shape dictated by the slot, and adhesively secured to the core while it retains the shape of the slot.
