ABSTRACT:
To simplify the cleaning and maintenance of a meltblowing head, the lips defining with the spinneret the flowing slits adjusting the row of orifices can be swung away from the spinneret on respective lip guides pivotally connected to respective setback bars. The setback bars can be adjusted and locked in place with respect to the blowing housing and the lips can be adjusted and locked in place relative to the lip guides independently of the swinging action.
