  • Patent number: 9828180
    Abstract: A fabric carcass defines the base of a conveyor belt. A first polymer is coated or otherwise disposed over an exterior side of the fabric carcass to cure with a first layer thickness. The first polymer may be a polyvinyl chloride resin with a plasticizer additive to provide an added robustness to belt at a relatively low cost. Due to deterioration that may occur when certain polyvinyl chloride resins are used as the exterior surface of the conveyor belt, a second polymer is disposed over the cured layer of polyvinyl chloride to define an exterior surface that is configured for resiliently interfacing with a die press of a cutting or stamping station. The second polymer may be a polyester to provide improved resiliency and an exterior surface with better durability than the first polymer.

    Abstract: A device for applying a coating material to an optical fiber (1) has a coating nozzle (7) arranged in a nozzle holder (3) and a coating chamber (17) located before the coating nozzle (7) in the direction of travel of the optical fiber (1). Beyond that the device has at least one inlet channel (19) which is connected to the coating chamber (17), as well as a number of feed lines (23) for different coating materials. A connection can be established between one of the feed lines (23) and the at least one inlet channel (19), so that a change of coating material can be made in a simple manner, particularly a color change, without costly conversion and cleaning operations.

  • Patent number: 5922128
    Abstract: In a device for the coating of a running web of paper or cardboard, provisions are that in a press gap formed between two rolls a coating substance applied in a very small quantity on the surface of the one roll is first pressed on the web leaving a very thin coat on the web which, however, covers all spots including the "mounds" of microroughness. Next, the second coat can be applied and dosed on the still moist first coat with the usual means. In the process, the first coat is preferably dosed on the shell of the first roll, by means of the peripheral grooves of a rotary doctor. The same may be performed also as regards the second coating on the web.

  • Patent number: 5904775
    Abstract: An applicator device for applying a coating agent onto a moving base, such as a paper or board web, onto the face of a film press roll, or equivalent, and a method for correcting for distortions arising from thermal strains in such an applicator device. The applicator device includes an applicator beam arranged in a direction transverse to a running direction of the moving base, a coating-agent feed pipe arranged in the transverse direction and mounted on the applicator beam, and coating members mounted on the applicator beam for applying a coating onto the moving base and spreading and smoothing the coating agent onto the moving base. The coating-agent feed pipe and the coating members are constructed as a single unit. The device also includes mounting members for mounting the single unit of the coating-agent feed pipe and the coating members on the applicator beam.

  • Patent number: 5902400
    Abstract: The invention concerns a device (1) for applying a substance (9) to a surface (3), the device comprising a carrier beam (2) and a doctor blade unit (40) which can be pressed magnetically against the surface (3). Provided between the doctor blade unit (40) and the carrier beam (2) is a holder connection (5) which produces play transversely to the surface (3). The holder connection (5) comprises at least one pair of sliding holder elements (51, 52) which can move only in translation, interact and form a sliding guide plane (500) which can be aligned on the region of the doctor blade element application zone (31). The holder elements are interconnected in a manner rigid against tilting such that all the moments due to thrust forces on the doctor blade unit (40) act with respect to a point of application on the carrier beam without losses of moments.

  • Patent number: 5858090
    Abstract: An apparatus for applying a liquid or pasty medium, i.e. a coating medium onto a moving material web, in particular consisting of paper or board. At least one application unit applies the medium. A roll associated with the application unit receives the medium. The application unit has an application doctor blade and has a cleaning doctor blade which is arranged at a distance from the application doctor blade in the direction opposite the direction of rotation of the roll. The cleaning doctor blade together with the application doctor blade defines an application chamber for the medium. In order to prevent the collection and build-up of fibers, foreign bodies and similar particles upstream of or on the entrance side of the cleaning doctor blade, as far as possible, the cleaning doctor blade is equipped with a blade bar which is supported by a holder.

  • Patent number: 5846015
    Abstract: A coupling member for joining a first article to a second article comprising first and second elongate arms that are pivotally connectable to a main housing via ball and socket joints. Each arm has one end formed for connection to one of the articles and the other end adapted to be engaged in the ball and socket joint. A locking system is also provided to lock the arms in position with respect to the main housing after the arms have been connected between the first and second articles to create a rigid connection between the first and second articles. The pivotable nature of the coupling member allows for a connection to be made between the first and second articles to be joined without the articles being in perfect alignment whereupon the locking system is applied to create a rigid link.
