  • Patent number: 9272301
    Abstract: Non-contact method and apparatus for Drying, Conditioning, Shaping and Manipulating of sheet fed Media. These functions are performed either on one side, or simultaneously or delayed one from the other on both sides, of the Media. For Drying, the energy applied is minimized to that necessary to supply latent heat of vaporization permitting use in, for example, low cost printers. No friction is introduced in the transport path enabling high speed, reliable Media transport. A region is established between Media and Platen wherein heat, support, and chemical or other processing may occur in a controlled way. Relatively few, inexpensive, and small parts are needed lowering the cost, energy, and space requirements for performing the various functions allowing for new applications in many fields. Media is supported a specific distance from a Platen by a balance of Fluid forces. The Media and the Platen bound a region in which forced convection greatly enhances process rates otherwise be limited by diffusion.

The machine uses heat sources located along the barrel to heat the source material while an auger screw transports the source material in the barrel. This transport step does not shear the source material, nor does it use friction to produce the heat necessary to melt the source material. The material becomes substantially liquid or melted during the heating process, and the melted material is forced, by the auger screw, into a chamber whereupon a plunger, situated concentrically with the auger screw, injects the material from the chamber into a mold. Sensors located along the barrel and in the chamber ensure consistency between mold cycles. The controller dynamically adjusts the injection molding process to achieve more consistent and reliable molded parts.

    Abstract: The present invention provides a method for producing a resin bottle formed from a preform as a prototype by a blow molding process. The method comprises: a first step of measuring each of weights or wall thicknesses of a plurality of inspection parts set in a body portion of the preform; a second step of comparing each of the weights or the wall thicknesses measured by the first step with a preset set value, and thereby inspecting a difference between each of the weights or the wall thicknesses measured by the first step and the set value for each of the inspection parts; and a third step of adjusting a condition for blow molding in the blow molding process in accordance with an inspection result of each of the inspection parts.

    Abstract: A method for blow molding containers in blow molds of a device operated with the recovery of air from the blow molds, where operation is accomplished consecutively in a preblow stage with a low pressure and at least two further blow stages with respective higher pressures, and where subsequently, in a recovery phase with several pressure stages, air is fed from the respective blow mold, air from the blow mold is first fed into the volumes allocated to the preblow stage, with priority over a feeding at least into the volume allocated to the pressure stage following the preblow stage. Further, a blow control and a control means for the pressure in the volume, where the blow control has a program section for primarily feeding air first into the volume, and possibly for limiting the pressure in the volume to a multiple of the pressure.
