  • Patent number: 4704183
    Abstract: A press for applying an overlay to the front and sides of an elongate workpiece. Elongate edge margins of a forming sheet are manipulated through actuation of arrays of sheet-manipulating and positioning piston-cylinders to cause the forming sheet to wrap around the workpiece and during such wrapping to press an overlay against the workpiece. Tray assemblies support a workpiece while the overlay is applied, and these are mounted from movement from within to outside the press, to facilitate reloading of the press.

  • Patent number: 4614488
    Abstract: An overlay molding press which includes a pair of oppositely disposed jaw members. Each jaw member is provided with an elongate shoulder extending therealong and each jaw member has a forming surface extending its length with an edge of the surface at the shoulder of the jaw member. The forming surfaces of the two jaw members collectively form a mold cavity. The jaw members are rockable about an axis extending where their shoulders meet to produce a folding together of their forming surfaces and a decrease in the lateral dimension of the mold cavity.
