Abstract
Glass sheet handling devices are provided with glass sheet engaging surfaces composed of a phenolic resin reinforced with fibers of an aromatic polyamide composition. In a specific embodiment of this invention, a sufficient number of said fibers extend to an exposed surface of said devices to develop a coefficient of friction sufficient to prevent relative sliding between the exposed surface of said glass sheet engaging member and said glass sheet.
Claims6
Apparatus for handling a hot glass sheet during conveyance comprising a ring-like support member having a surface adapted to engage a heat-softened glass sheet and further having a relatively thin upper edge portion and a relatively thick lower portion, said surface consisting essentially of a phenolic resin reinforced with fibers composed of an aromatic polyamide composition, and means to support said ring-like member in an essentially horizontal orientation with the width of said ring extending essentially vertically to place an upper edge of said ring-like member in position to receive said hot glass sheet.
