A portion of the positioning device guides the continuous strand of material through the bath, or guides the strand to pass along the bottom of the passageway, and the saturated or partially saturated strand of material then exits from an outlet of the passageway to a point in the path of filter tow material that is being converged to form a filter rod.Type: GrantFiled: February 24, 2010Date of Patent: November 12, 2013Assignee: Philip Morris USA Inc.Inventors: Robert C.

Patent number: 8534294Abstract: Provided are a method and apparatus for making a cigarette filter assembly for potentially reducing particle breakthrough. The method includes forming a lofty porous network of charge retaining polymer fibers by mechanical, chemical or thermal bonding of the fibers, wrapping the lofty porous network in a cylindrical or tubular shape with optional mediating filter fibers in a filter paper to form a filter plug while maintaining the lofty structure. The charge retaining fibers can be charged to attract and hold particles from such sources as particulate matter from sorbents (preventing break-through), and smoke constituents while having a suitable pressure drop. The apparatus handles the lofty media with minimal crushing, for example, by spacing apart delivery rolls equipped with protrusions to punch, push, and/or pull the lofty media ahead for high speed operation.Type: GrantFiled: October 9, 2009Date of Patent: September 17, 2013Assignee: Philip Morris USA Inc.Inventors: Szu-Sung Yang, Lixin L. Xue, Jing C. Chang

Patent number: 8512213Abstract: Cigarette filter rods having individual objects positioned at predetermined intervals therein are prepared by transferring the individual objects from a rotating horizontal pan to a rotating vertical wheel and then depositing the object into a web of filter tow. Each object is positioned within the moving web of tow. The web filter material and the objects positioned within the web are introduced into a rod-forming unit wherein the rod is formed. The rate of feed of the filter tow, the rate of rotation of the horizontal pan and the vertical wheel are controlled relative to one another such that objects are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.Type: GrantFiled: February 20, 2012Date of Patent: August 20, 2013Assignee: R.J. Reynolds Tobacco CompanyInventor: Philip Andrew Deal

Patent number: 8496569Abstract: A manufacturing machine includes a group-forming unit for forming filter portion groups, each group having at least two different filter portions aligned axially and contacting at the ends; a winding unit that receives a succession of groups from the group-forming unit, winds a strip of wrapping material about the groups to form a continuous filter rod, and cuts combination filters off the rod by cyclically cutting the rod transversely; and a transfer unit that transfers the groups from the group-forming unit, in which the groups travel transversely, to the winding unit, in which the groups travel axially. The transfer unit has at least one spider that feeds the groups successively into a forming beam of the winding unit, and at least one release drum that releases the groups successively to the spider. The release drum is mounted to move between a work position and a maintenance position.Type: GrantFiled: July 17, 2009Date of Patent: July 30, 2013Assignee: G.D Societa' per AzioniInventors: Leonardo Balletti, Marco Esposti
