Abstract
A device for continuous coating of fibers has a horizontally mounted cylindrical mixing container with an inlet for fibers at one end and an outlet for coated fibers at the other end. The container has a mixing shaft mounted coaxially therewithin, which shaft is driveable at a considerably supercritical speed. The shaft is at least partially hollow and is provided with a glue feed through its interior. In a glue feed zone of the container the shaft is provided with glue agitating elements projecting therefrom and dispensing glue to the ring of fibers formed in the vicinity of the wall of the container. The shaft also has ventilator ridges mounted thereon extending radially outwardly for most of the length of the shaft, which ventilator ridges support mixing tools which extend into the ring of fibers.
Claims18
A device for continuous coating of fibers, comprising:
- a horizontally mounted cylindrical mixing container;
- an inlet funnel entering into one end of said container;
- an outlet funnel connected to the other end of said container;
- a mixing shaft mounted coaxially within said container, said shaft being at least partially hollow;
- drive means connected to said mixing shaft for driving said shaft at considerably supercritical speeds;
- glue feed means for feeding glue into at least a portion of the interior of said shaft;
- mixing tools connected to said shaft at least on an axial portion thereof;
- glue agitating elements connected to said shaft on an axial portion thereof and extending into the ring of material formed on the inside wall of the cylindrical mixing container when said shaft is operated at a considerably supercritical speed, said elements being in the form of mixing rods extending into the ring of material, each of said rods being provided with at least one groove extending in the lengthwise direction, each of said grooves being open outwardly along its entire length and each of said grooves communicating with the interior of said mixer shaft for allowing dispensing of glue into the ring of material;
- and
- means for ensuring air vorticization in said cylinder;
- whereby fibers may be substantially homogeneously coated while avoiding substantial jamming and lumping of the fibers in the mixing container.
A device for continuous coating of fibers, comprising:
- a horizontally mounted cylindrical mixing container;
- an inlet funnel entering into one end of said container;
- an outlet funnel connected to the other end of said container;
- a mixing shaft mounted coaxially within said container, said shaft being at least partially hollow;
- drive means connected to said mixing shaft for driving said shaft at considerably supercritical speeds;
- glue feed means for feeding glue into at least a portion of the interior of said shaft;
- mixing tools connected to said shaft at least on an axial portion thereof;
- means for ensuring air vorticization in said cylindrical mixing container including a plurality of ventilator ridges mounted on said shaft, said ventilator ridges being distributed along the circumference of said shaft, extending radially therefrom and each extending over a large portion of the length thereof;
- glue agitating elements connected to said shaft on an axial portion thereof and extending into the ring of material formed on the inside wall of the cylindrical mixing chamber when said shaft is operated at a considerably supercritical speed, said elements being in the form of outwardly tapering mixing rods extending into the ring of material and being replaceably mounted on said ventilator ridges, said rods being each provided with at least one groove extending in the lengthwise direction and communicating with the interior of said mixer shaft, thereby allowing dispensing of glue into the ring of material;
- and
- mixing rod support means for mounting said mixing rods on said ventilator ridges.
