Patent number: 7692123Abstract: A manufacturing machine manufactures a heat-source rod having a rod-like extrusion-molded article made from a combustible material with axial grooves in the cylindrical surface thereof and a heat-insulating web enveloping the article, and is provided with a apparatus 10 for spouting water to the web W in the process of the web W being fed to a wrapping section 4. The spout apparatus 10 includes an air vibrator 12 with a vibrating rod 34, and a flexible nozzle 36 attached to the rod 34 to extend across the rod 34 and supplied with water from a rate regulating pump 42. While the web W is being fed, the end of the nozzle 36 spouts water to the web W, reciprocating widthways relative to the web W due to vibration of the rod 34, and the water spouted dissolves a binder used in the web W to bind heat-insulating fiber, thereby forming a wet band H, where the wet band H has a waveform continuing along the longitudinal direction of the web W and provides a adhesive region for bonding the article.Type: GrantFiled: April 24, 2007Date of Patent: April 6, 2010Assignee: Japan Tobacco Inc.Inventors: Yasuo Baba, Hajime Ohinata, Nobuo Hosoya, Toshio Yanagi

Patent number: 6945859Abstract: A method and apparatus for controlling the coherence of a high-pressure fluid jet directed toward a selected surface. In one embodiment, the coherence is controlled by manipulating a turbulence level of the fluid forming the fluid jet. The turbulence level can be manipulated upstream or downstream of a nozzle orifice through which the fluid passes. For example, in one embodiment, the fluid is a first fluid and a secondary fluid is entrained with the first fluid. The resulting fluid jet, which includes both the primary and secondary fluids, can be directed toward the selected surface so as to cut, mill, roughen, peen, or otherwise treat the selected surface. The characteristics of the secondary fluid can be selected to either increase or decrease the coherence of the fluid jet. In other embodiments, turbulence generators, such as inverted conical channels, upstream orifices, protrusions and other devices can be positioned upstream of the nozzle orifice to control the coherence of the resulting fluid jet.Type: GrantFiled: June 21, 2004Date of Patent: September 20, 2005Assignee: Flow International CorporationInventors: Mohamed A.
