摘要： A thermoforming platen is provided having a tooling support plate and a plurality of discrete load paths. The tooling support plate has a top tooling surface, a bottom surface, and an outer periphery. The plurality of discrete load paths interconnect the bottom surface with one or more external load sources operative to distribute and centralize load deformation of the top plate from forming loads. The load paths are provided laterally inboard of the top tooling surface at one of a plurality of inboard locations to impart minimized tooling surface deformation along the top plate tooling surface. A method is also provided.

摘要： A thermoforming apparatus is provided having a frame, a pair of platens, and a platen drive assembly. The platens are carried by the frame on opposite sides of a sheet line each configured to carry a respective die. One platen has a proximal die surface adjacent the sheet line and a rear surface distal the sheet line. The platen drive assembly is interposed between the frame and the one platen and has at least one reciprocating kinematic linkage and a drive motor configured to reciprocate the one platen to and fro relative to another platen. The kinematic linkage has a plurality of links interconnected pivotally together with respective rotation joints and interposed between the frame and the one platen. An outboard-most rotation joint is provided proximate one end of the frame and an inboard-most rotation joint intermediate the rear surface and the proximal die surface. A method is also provided.

摘要： A thermoforming apparatus is provided having a frame, a pair of opposed platens, a toggle shaft, a kinematic linkage, a form air manifold, and a pair of articulating bearing assemblies. The pair of opposed platens is carried by the frame each with a die, one die configured to engage an opposed face of another die across a heated sheet of thermoformable material in sealed relation there between. The toggle shaft is carried by the frame for rotation. The kinematic linkage is coupled between the toggle shaft and one of the dies. The form air manifold and a source of differential pressure is coupled with a die face on one of the dies. The pair of articulating bearing assemblies is carried by the frame and configured to support the at least one toggle shaft for translation towards and away from the another die and platen. A method is also provided.

摘要： A thermoforming apparatus is provided having a pair of coacting platens, a load bearing structural member, a force applicator, and a deformation sensor. The pair of coacting platens and respective dies are configured to mate on opposed surfaces of a heated sheet of thermoformable material to form articles. The load bearing structural member is configured to carry the coacting platens and the dies in complementary closed relationship about the sheet during an article forming operation. The force applicator is carried by the structural member and configured to impart a forming load between the pair of opposed dies and platens and across the structural member during a forming operation. The deformation sensor is configured to span a first location and a second location on the structural member to detect deformation indicative of separation between the dies resulting from deformation. A method is also provided.

摘要： A thermoformable sheet transfer system is provided having at least one frame, and upstream conveyor, a sheet cutter, and a downstream sheet manipulator. The upstream conveyor is configured to deliver a series of shots of formed articles in a thermoformed sheet from an exit end of an article forming station. The sheet cutter is carried by the at least one frame provided proximate the conveyor downstream of the article forming station and is configured to cut a leading edge of the formed articles and sheet sufficiently formed to index within dies of an article trim press. The downstream sheet manipulator is carried by the at least one frame and is configured to transport the leading edge and the sufficiently formed articles and sheet for delivery in sequential shots from downstream an article forming station to upstream an article trim station. A method is also provided.
