| In one embodiment, a method for forming a dry lamination for a composite fiber material structure, for example a wind turbine blade, includes cutting at least two plies of composite fiber material according to a predetermined pattern, arranging the at least two cut plies of composite fiber material in a predetermined arrangement relative to each other, stitching the at least two cut plies together using a thread to secure the at least two cut plies in the predetermined arrangement to form the dry lamination, and spooling the dry lamination into a single roll. The dry lamination can then be transported without misaligning the plies and placed into a resin infusion tool without requiring manual placement of individual plies of composite fiber material. | ||||||

| 187 | PREFORMS FOR FLAIR APPLICATIONS | US13330632 | 2011-12-19 | US20120187067A1 | 2012-07-26 | Wilhelmus Johannes Joseph Maas; Petrus Lambertus Wilhelmus Hurkmans; Aaron S. Haleva |
| A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. An outer preform can be fashioned first, then an inner preform molded through a center hole in the outer preform's bottom. The preforms are then connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or the same, e.g., PET/PET—if mutual bonding during the molding of the second is prevented. A non-stick coating can be sprayed on a surface portion of the first preform touching the second perform, then the second container molded. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the perform first molded, followed by molding of the other. | ||||||

In another aspect of the invention there is provided a handled plastic container, said container comprising a low molded plastic bottle and a separate handle interconnected thereto wherein the handle includes upper retaining means and lower retaining means, said upper retaining means including a lug or protrusion, and the bottle including a neck finish having an engagement portion co-operate with said lug or protrusion connecting said upper retaining means with said bottle, and wherein the lower retaining means in integrated with a portion of a sidewall of the bottle. | ||||||
| 192 | Process for forming fibrous structures with predetermined Z-fiber distributions | US09513478 | 2000-02-25 | US06237203B1 | 2001-05-29 | Philip William Sheehan; Ronnie Sze-Heng Liew |
| The invention relates to the field of forming fibrous structures by needling processes. A process is provided for achieving a desired Z-fiber distribution in a fibrous structure by controlling transport depth during formation of the fibrous structure in a series of needling passes.

| 193 | Method of manufacturing a pipe liner bag | US974835 | 1997-11-20 | US6136135A | 2000-10-24 | Takao Kamiyama; Yasuhiro Yokoshima; Shigeru Endoh; Hiroyuki Aoki |
| The present invention provides a method of readily manufacturing a multi-layer pipe liner bag with a good workability. A guiding tube is inserted into an outer layer composed of a tubular resin absorbent material and a plastic film coated over the outer periphery of the tubular resin absorbent material. An inner layer composed of another tubular resin absorbent material is inserted into the guiding tube, and the guiding tube is extracted with the outer layer and the inner layer being fixed. The tubular resin absorbent materials of the outer layer and the inner layer are with thermosetting resin to complete the pipe liner bag. Since the outer layer and the inner layer are manufactured separately, the manufacturing of the respective layers can be performed with a good workability. Also advantageously, the plastic film covering the outer surface of the outer layer can be prevented from scratches and so on. | ||||||
| 194 | Method for fabricating composite structures using pultrusion processing | US936783 | 1997-09-23 | US6033511A | 2000-03-07 | Gary L. Farley |
| A method for fabricating composite structures at a low-cost, moderate-to-high production rate. A first embodiment of the method includes employing a continuous press forming fabrication process. A second embodiment of the method includes employing a pultrusion process for obtaining composite structures. The methods include coating yarns with matrix material, weaving the yarn into fabric to produce a continuous fabric supply and feeding multiple layers of net-shaped fabrics having optimally oriented fibers into a debulking tool to form an undebulked preform. The continuous press forming fabrication process includes partially debulking the preform, cutting the partially debulked preform and debulking the partially debulked preform to form a net-shape. An electron-beam or similar technique then cures the structure. The pultrusion fabric process includes feeding the undebulked preform into a heated die and gradually debulking the undebulked preform. The undebulked preform in the heated die changes dimension until a desired cross-sectional dimension is achieved. This process further includes obtaining a net-shaped infiltrated uncured preform, cutting the uncured preform to a desired length and electron-beam curing (or similar technique) the uncured preform. These fabrication methods produce superior structures formed at higher production rates, resulting in lower cost and high structural performance. | ||||||
| 195 | Method of molding a laminated foamable sheet | US884785 | 1986-07-11 | US4798763A | 1989-01-17 | Hamid G. Kia |
| A method of molding and forming a laminated foamable sheet which contains a solid catalyst that is activated at the molding temperature of the laminate. A laminated foamable sheet is first provided by saturating a glass fiber mat with a urethane foam composition containing a solid catalyst of stearate salt and then sandwich it between two layers of cover sheet. The solid catalyst contained in the urethane composition cannot be activated until it is heated to the molding temperature of the laminated sheet. The laminated foamable sheet is then positioned into a mold having two heated platens and a cavity defined therein with the mold temperature set at a temperature of at least that of the melting point of the solid catalyst contained in the urethane composition. The solid catalyst in the composition melts and causes the urethane precursors to start the foaming reaction such that the laminate expands and fills the cavity of the mold. After a sufficient length of time during which the foamed sheet is cured under heat and pressure, a completed part in the shape of the cavity is removed from the mold. | ||||||
| 196 | Method for producing cigarette packages | US3732663D | 1970-05-06 | US3732663A | 1973-05-15 | GELDMACHER E |
| The specification describes a method for the production of cigarette packages in which a first foil web of thermoplastic material, supplied from the supply roll, and having a width exceeding the length of the cigarettes to be packed, is pressed into troughs corresponding to the size of the cigarettes to be packed, cigarettes are placed in the troughs, a second flat web of foil supplied from a second supply roll is placed over the cigarettes to cover them and the webs are connected together. Following this the two webs are separated to form sections which constitute substantially complete packages. The shaping of the troughs accepting the cigarettes individually occurs in the one first foil web on a drum provided with molds which can be placed under suction.
