Abstract
A spinneret cleaning device for removing deposits quickly, reliably and uniformly has an adjustable force flat plane cleaning blade.
Claims6
A portable device for cleaning operating spinnerets for molten synthetic polymers in a spinning housing comprising:
- at least one cleaning blade movable in a plane parallel to the face of the spinneret, said blade being fixedly attached to a base plate;
- a rotatable shaft and rotation means therefore;
- pin means eccentrically located on one end of the shaft for movably attaching the base plate thereto;
- a stop plate having means for aligning the device relative to said spinneret housing;
- means for positioning said shaft relative to said stop plate and constraining shaft movement of the shaft substantially toward the spinneret face, the movement in said pin means being sufficient to allow said cleaning blade to conform to said spinneret face and compensate for the difference in alignment between the spinneret housing and face.

A portable device for cleaning the face of a molten synthetic polymer spinneret during operation comprising a stop plate having means thereon for aligning the stop plate with the housing for said spinneret;
- a rotatable shaft and means for rotating the same;
- a ball pin eccentrically attached to one end of said shaft, a base plate having a socket means for attachment to said ball pin;
- at least one cleaning blade attached to said base plate, the blade being substantially parallel to said spinneret face when said stop plate is aligned with said spinneret housing;
- means attached to said shaft for guiding said shaft relative to the stop plate and increasingly resisting force of movement of said shaft toward said spinneret face;
- and means for cleaning said blade after contact with said spinneret face.
