A peeling apparatus including a holding table adapted to carry an optical disc composed of upper and lower disc-shaped substrates laminated to each other, a boss disposed centrally of the holding table which allows gas to blow between the disc-shaped substrates, and a suction means peripherally of the holding table to suck pulverized adhesive dust exhausted from the disc-shaped substrates when the two disc-shaped substrates are peeled from one another. The suction means is provided with a suction groove so formed to correspond to the periphery of the two disc-shaped substrates, and the holding table is provided with sucking and holding means for sucking and holding the two disc-shaped substrates.
A method for peeling upper and lower disc-shaped substrates from one another, wherein the upper and lower disc-shaped substrates are laminated by an adhesive to form an optical disc, wherein gas is blown from a center hole defined in said optical disc between said upper and lower disc-shaped substrates to separate same from one another, and wherein an adhesive powder dust is exhausted from the periphery of the substrates.
A peeling apparatus comprising a holding table for supporting an optical disc including upper and lower disc-shaped substrates laminated to each other, a boss disposed centrally of said holding table for blowing gas between the disc-shaped substrates, and a suction arrangement disposed peripherally of said holding table for absorbing an adhesive powder dust during peeling of said upper and lower disc-shaped substrates from one another.
A peeling apparatus comprising a holding table for supporting an optical disc including upper and lower disc-shaped substrates laminated to each other, a boss disposed centrally of said holding table for blowing gas between the disc-shaped substrates, wherein said holding table is formed with a circular flange for receiving gas exhausted from the periphery of the disc-shaped substrates.
A peeling apparatus comprising a holding table adapted to carry an optical disc composed of upper and lower disc-shaped substrates which are laminated to one another, a boss disposed centrally of said holding table which allows gas to blow between the disc-shaped substrates, and a suction device disposed peripherally of said holding table for sucking pulverized adhesive dust exhausted from the disc-shaped substrates when same are peeled from one another, said suction device including a suction groove formed to correspond to the peripheral ends of the disc-shaped substrates, said holding table including an arrangement which applies suction to and holds the disc-shaped substrates thereon.
