| 20080277840 | Method of injection stretch blow molding heatproof bottles - A preform of injection-molded PET has a body wall thickness of 3.0-4.5 mm. The preform is high-temperature mold-released from an injection cavity mold and an injection core. Pre-blowing of the preform is restricted at 5±0.5 seconds after the mold release, at a temperature of 112-117° C. of the pre-blow mold, and for a pre-blowing time of 0.5-1.0 second. Air blowing is applied to expand only the body of the preform. Stretch blow molding is performed restrictively at 3-4 seconds after the mold release from the pre-blow mold, at a temperature of 103-107° C. of the blow mold, and for an air blowing time of 6-9 seconds, thereby stretch blow molding the preform into a bottle and simultaneously heat setting to impart heat resistance to the bottle. | 11-13-2008 |
| 20110057362 | METHOD AND DEVICE FOR BLOW MOLDING CONTAINERS - A method for blow molding containers having cross-sections of a non-circular shape from preforms, in which a temperature profile varying at least in the circumferential direction of the preform is produced by means of at least one heat transfer element, for which purpose the preform and at least the heat transfer element are oriented toward one another by a relative rotational movement in the circumferential direction of the preform, the heat transfer element is rotated relative to the stationary preform about a heat transfer element axis during the relative rotational movement. Further, a device for blow molding such containers where the heat transfer element and the holder are rotatable about a heat transfer element axis and are coupled with a rotational drive. | 03-10-2011 |

| 20090091066 | METHOD OF MAKING AN IMPROVED BALLOON CUFF TRACHEOSTOMY TUBE - There is provided a method of making a balloon having a differential thickness. The method uses a raw tube composed of a thermoplastic polymer which is placed in an asymmetrical mold. The tube is preheated in the mold to a temperature sufficient to soften the material of the tube and inflated with a gas to generally uniformly stretch the material of the tube while allowing the tube to retract lengthwise, thus forming a balloon. The resulting completed balloon has a differential wall thickness wherein the upper region has a thickness of from about 15 to about 30 micrometers and the lower region has a thickness of from about 5 to about 15 micrometers. | 04-09-2009 |
| 20090236776 | PROCESS FOR MAKING A STRETCH-BLOW MOULDED CONTAINER HAVING AN INTEGRALLY MOULDED HANDLE - The present invention relates to a process for making a container having an integral handle, comprising the steps of:

| 264522000 | Starting material is nonhollow planar finite length preform or product is planar and of finite length | 1 |
| 20090020923 | CONTINUOUS PRODUCTION OF PLASTIC SIDING PANELS WITH SEPARATE SHINGLE APPEARANCE - 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. | 01-22-2009 |
