Abstract
Embodiments provide a lamination machine and lamination process for laminating a membrane to a three-dimensional (3D) target surface of an article, such as a footwear article, glove, clothing article, backpack, or other article. The lamination machine may include an inflatable former that is permeable to air. The inflatable former may have a shape that generally corresponds to a shape of the target surface. The membrane and target surface may be arranged on the former, with a heat-activated adhesive disposed between the membrane and the target surface. The lamination machine may further include a pump to pump heated compressed air into the former. The heated compressed air may inflate the former to press the membrane against the target surface and to activate the adhesive to bond the membrane to the target surface.
