  • Publication number: 20230347595
    Abstract: A method and system for manufacturing a three-dimensional porous structure. Filaments are deposited in a predetermined interconnected arrangement in a plurality of stacked layers for forming a porous structure with interconnected pores. A pressure value indicative of a pressure being applied on the build material in the build material reservoir of a nozzle used for deposition is monitored during deposition of the filaments. The processing unit is configured to adjust at least one extrusion parameter in order to compensate for the irregular rising and/or falling of the pressure value.

  • Publication number: 20220230854
    Abstract: Apparatus for plasma processing of a continuous fiber, comprising a first and a second plasma torch. Each plasma torch comprises oppositely arranged electrodes to define a plasma discharge chamber between the electrodes. The plasma discharge chamber comprises an inlet and an outlet for passing a plasma forming gas between the electrodes. The apparatus further comprises an afterglow chamber in fluid communication with the outlets of the plasma discharge chambers, which comprises a substrate inlet and a substrate outlet arranged at opposite sides of the outlets of the plasma discharge chambers. A transport system is configured to continuously transport the fiber from the substrate inlet to the substrate outlet through the afterglow chamber. The substrate inlet comprises an aperture having a cross-sectional size substantially smaller than a cross-sectional size of the afterglow chamber. The outlets of the plasma torches face each other and exhaust plasma activated species into the afterglow chamber.

  • Publication number: 20180169699
    Abstract: The present invention is directed to a method of making a cord-reinforced rubber article, comprising the steps of A) mixing a carrier gas, a sulfur-containing compound and an alkyne, to form a gas mixture; B) generating an atmospheric pressure plasma from the gas mixture; C) exposing a reinforcement cord to the atmospheric pressure plasma to produce a treated reinforcement cord; and D) contacting the treated reinforcement cord with a rubber composition comprising a diene based elastomer.

  • Patent number: 9255330
    Abstract: A continuous plasma treatment process is disclosed. The process may include providing at least one plasma treatment zone having a pair of electrodes with endless dielectric belts, each belt having a first and a second side that covers one of the electrodes. The process may include producing a non-thermal plasma in a space between the belts, and transporting a web material via the belts such that there is a width of exposed belt on either side of the web material. The process may include transporting the web material such that a side of the web material not in contact with the belts is treated in two passes through the at least one plasma treatment zone, while exposed parts of the belts transporting the web material are also treated. The process may include cleaning treated parts of the belts prior to the belts re-entering the at least one plasma treatment zone.

  • Publication number: 20130084409
    Abstract: A continuous plasma treatment process, said process comprising the steps of: providing a plasma treatment apparatus, said apparatus comprising at least one plasma treatment zone, said plasma treatment zone comprising a pair of electrodes with endless dielectric belts each having a first and a second side and each covering an electrode of said pair of electrodes; producing a non-thermal plasma in a process gas at a pressure of 100 Pa to 1 MPa in the space between said pair of endless dielectric belt-covered electrodes by applying a voltage between said electrode pair; providing a web material to be treated such that it can be transported by said two endless dielectric belts in such a way that there is an area in the plane of said belt at least about 5 mm on either side of said web material on the side of said endless dielectric belts with no part thereof facing one electrode of said pair of electrodes; transporting said web material using said endless dielectric belts in frictional contact with said electrodes
