US Patent:

44307845, Feb 14, 1984

Filed:

Feb 9, 1981

Appl. No.:

6/232457

Inventors:

Kenneth Brooks - Charlotte NC
Paul R. Smith - Princeton WV
Thomas E. Morris - Concord NC

Assignee:

Celanese Corporation - New York NY

International Classification:

B23P 1516

US Classification:

29157C

Abstract:

A single or multi-orifice metal nozzle structure suitable for use in an ink jet printing system. The metallic nozzle member has at least one orifice extending therethrough, the orifice including a cylindrical portion, adjacent the outlet face of said nozzle, having a height ranging from 0. 25 to 5 times its diameter and at least one frustoconical section divergent toward the face opposite the outlet face and communicating with the cylindrical portion. Where the metal nozzle is a multi-orifice metal nozzle, each frustoconical section communicates with a groove disposed in the face opposite the outlet face. The multi-orifice metal nozzle is prepared by grooving a metal plate with at least one groove, punching a plurality of frustoconical sections into the groove member and then forming a cylindrical portion into each frustoconical section and through the plate member.

International Classification:

B31C 1300

US Classification:

493 44

Abstract:

The present invention relates to high speed process and apparatus suitable for the preparation of cigarette filter rods having high tow utilization in terms of pressure drop per unit rod weight without producing substantial tow density variations. In accordance with this invention, it has been discovered that in a process for manufacturing filter elements from opened and deregistered crimped continuous filament tow, wherein said tow is conducted from a mechanical forwarding means through an aspirating jet positioned adjacent a compacting means and wherein means are provided for dissipating aspirating fluid, that filter rod pressure drop and weight variations are reduced by aspirating at low pressures and more specifically, at fluid pressures of not more than about 3 pounds per square inch gauge and by causing the aspirating fluid, at its point of contact with the continuous filament tow, to flow substantially in a direction axial to that of the tow.
