  Method for making resilient tubingUSPTO Application #: 20070023132Title: Method for making resilient tubing Abstract: A method for forming a tubular member includes preparing a longitudinal Teflon strap, winding the Teflon strap around a longitudinal core to form a tubular prototype having two or more layers, and welding the two or more layers of the Teflon strap together to form the tubular member. The layers of the Teflon strap are preferably arranged at different angles or inclined relative to each other, or arranged at different angles with respect to the longitudinal axis of the core or of the elongate tubular member. The tubular member may further be shaped to various shapes or configurations with such as extending, stretching, expanding, enlarging, or shaping process. (end of abstract) Agent: Charles E.

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a method, and more particularly to a method for making tubings or tubular members having suitable resilience for allowing the tubings or tubular members to be enlarged or expanded to suitable or required dimensions or diameters or shapes. [0003] 2. Description of the Prior Art [0004] Typical tubings or tubular members or shafts may be made of composite materials or graphite fiber reinforced resin materials, and may comprise an oblong sheet or gore cut from a sheet of unidirectional graphite fibers impregnated with a plastic resin, which will be subjected with a hot-pressing process, to have the unidirectional graphite fibers and the impregnated plastic resin to be hardened or cured to form the tubings or tubular members or shafts. [0005] For example, U.S. Pat. No. 4,084,819 to Van Auken discloses one of the typical golf club shafts made of unidirectional graphite fibers and the impregnated plastic resin. However, due to the impregnated plastic resin, and after the hot-pressing process, the shaft will include a great hardness or stiffness that is non-flexible, and that may not be bent, and that may not be deformed or shaped to the other shapes or configurations. [0006] U.S. Pat. No. 4,133,623 to Bevan et al. discloses one of the typical rubber tubing made or produced or formed from extruding latex, and a number of complicated molding devices and valve devices and water jackets are required for forming or making the typical rubber tubings. Similarly, after the molding or mold injection process, the rubber tubing will also include a great hardness or stiffness that is non-flexible, and that may not be bent, and that may not be deformed or shaped to the other shapes or configurations. [0007] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional methods for making or forming tubings or tubular members. SUMMARY OF THE INVENTION [0008] The primary objective of the present invention is to provide a method for making tubings or tubular members having suitable resilience for allowing the tubings or tubular members to be enlarged or expanded to suitable or required dimensions or diameters or shapes. [0009] The other objective of the present invention is to provide a method for making tubings or tubular members having suitable resilience for allowing the tubings or tubular members to be used as auxiliary or artificial blood vessels, trachea, or other bioengineering uses, or the like. [0010] The further objective of the present invention is to provide a method for making tubings or tubular members having a number of orifices or perforations formed therein, for allowing the tubings or tubular members to be used as a filter device. [0011] In accordance with one aspect of the invention, there is provided a method for forming a tubular member, the method comprising preparing a longitudinal Teflon strap, winding the Teflon strap around a longitudinal core, to form a tubular prototype having at least two layers, and welding the two layers together to form the tubular member. The two layers may also be secured together with such as hot-pressing processes, or adhering processes, or the like. [0012] The Teflon membrane or strap may include a number of orifices or perforations formed therein, for allowing air to flow through the Teflon membrane or strap, and for allowing the Teflon membrane or strap 11 to be used as a filter member. [0013] The layers of the Teflon strap are arranged at different angles or inclined relative to each other, or arranged at different angles with respect to the longitudinal axis of the core or of the elongate tubular member. [0014] The tubular member may further be shaped to various shapes or configurations or structures or dimensions or outer diameters. For example, the tubular member may be extended, stretched, expanded, enlarged, or shaped into various shapes or configurations or structures or dimensions or outer diameters. [0015] The core may be removed or disengaged from the tubing or tubular member before or after the welding process, or the hot-pressing process, or the adhering process, to allow the tubular member to be extended, stretched, expanded, enlarged, or shaped into various shapes or configurations or structures or dimensions or outer diameters. [0016] Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
