ABSTRACT:
A method and apparatus for laminating two pieces of material involves edge bonding. The method includes the steps of: placing pieces of a first material into a fixture on a work platform, depositing a powder adhesive onto an edge zone of each first material piece, curing the adhesive to a form ready for bonding, placing pieces of a second material into the fixture such that each sits above a piece of the first material, applying heat and pressure to the fixture to press each piece of first material against each piece of second material, and removing the finished pieces from the fixture. The method utilizes a rotatable table carrying six equiangularly-positioned fixtures, as well as six workstations positioned equiangularly around the table. In the described embodiment, three of the workstations are automated: a mesh screen mechanism for depositing the powder adhesive, a bank of quartz infrared lamps for curing the adhesive, and a press mechanism for applying the heat and pressure to the pieces of material in the fixture.
