| 20090302511 | Method for Shaping Sheet Thermoplastic and the Like - Processes and apparati for shaping sheet glass or thermoplastic materials use force from a layer of a flowing fluid, such as air, between the sheet and a mandrel at close to the softening temperature of the thermoplastic. The shape is preserved by colling. The shape of the air bearing mandrel and the pressure distribution of the fluid contribute to the final shape. A process can be conducted on one or two surfaces such that the force from the air layer is on one or two surfaces of the sheet. The gap size between the sheet and mandrel determines the pressure profile in the gap, which also determines the final sheet shape. In general, smaller gaps lead to larger viscous forces.

| 20090194916 | Container, thermo-molding apparatus and method for thermo-molding the same - The present invention provides a bottomed cylindrical container, comprising a body wall, a bottom wall, and a ring-shaped foot downwardly extending from the bottom wall, said container being produced by thermo-molding a resin sheet, characterized in that said foot is formed by folding an inner wall by compressed fluid to be fusion-bonded with an outer wall, so as to form the foot comprising the inner wall and the outer wall. The present invention also provides a bottomed cylindrical container, comprising a body wall having a grounding edge at a lower end thereof, and a bottom wall, said container being produced by thermo-molding a resin sheet, characterized in that said bottom wall connects with an upper edge of an inner wall produced by folding back the body wall along the grounding edge and by fusion-bonding it to an inner periphery of the body wall. In addition, the present invention provides the methods for thermo-molding these containers and their apparatuses. | 08-06-2009 |
| 20100283190 | METHOD OF CONTINUOUSLY PRODUCING ELONGATED PLASTIC SIDING PANELS - A method and an apparatus for continuously producing elongated siding panels is disclosed. The apparatus includes a conveyor, a plurality of mold plates, and a die for extruding a sheet of material onto the mold plates. The mold plates are formed of a rigid material and positioned adjacent one another and supported by the conveyor for forming the elongated siding panels. Each of the mold plates has an upper edge portion and a lower edge portion with an intermediate portion therebetween. The intermediate portion has an aesthetic pattern for imparting the pattern to the sheet of material with the adjacent mold plates having different aesthetic patterns. The lower edge portion has a lower leg extending substantially perpendicular from the intermediate portion defining a horizontal plane and a projection portion between the lower edge portion and the intermediate portion extends beyond the horizontal plane for imparting a jagged pattern to the intermediate portion. | 11-11-2010 |
