Definitions
- the invention relates to a device for steam treatment of a running fiber strand according to the preamble of claim 1.
- the known device For the steam treatment of a running fiber strand, the known device has an elongate steam chamber which has an inlet roller pair at an inlet end for sealing the steam chambers and an outlet roller pair at an outlet end.
- the inlet roller pair is pressure-tightly connected to the steam chamber via an inlet chamber
- the outlet roller pair is likewise pressure-tightly connected to the steam chamber via an outlet chamber.
- the Ein ⁇ pair of rollers and the pair of outlet rollers each have two sealing rollers, which form a nip between them to guide the fiber strand.
- One of the sealing rollers is designed to be movable, so that an adjustment of the nip, which is adapted to the respective fiber type, is possible.
- the sealing rolls are pressed against one another, so that the fiber strand guided in the nip can seal into the steam chamber and / or escape.
- each device for Ab ⁇ sealing a steam chamber in which the sealing rollers are arranged outside the adjacent chamber, so that correspondingly relatively small steam chambers for the treatment of the fiber material can be realized.
- the known devices have two stationary sealing rollers, so that no Ein ⁇ adjustability of the nip is possible.
- the sealing between the adjoining chambers with respect to the peripheral surfaces of the sealing rolls is effected by plates resting against the circumference of the sealing rolls, so that a change in position of one of the sealing rolls would inevitably lead to leaks.
- Another object of the invention is to provide a device which is suitable in particular for high steam pressures.
