  • Method for providing a web of thermoplastic filaments
    Patent number: 6797101
    Abstract: An apparatus for providing a uniform web of filaments comprises tube filament transport means exiting through a confined zone of reduced turbulence, which preferably comprises a delivery slot. The delivery slot is configured with sidewalls substantially parallel to one another and to the transport tubes, so that filaments undergo minimal machine direction deflection in the slot. Charging means within the slot charge the filaments for further cross direction separation. A method of providing a uniform web of filaments comprises transporting filaments through transport tubes, through a tapered transition member, and into a delivery slot. The delivery slot is defined by sidewalls that are substantially parallel to one another and to the transport tubes, so that minimal machine direction deflection of the filaments occurs. The filaments are also charged by electrostatic charging means while they are in the slot for further separation.
