Abstract

1,247,436. Papermaking. BELOIT CORP. 7 March; 1969 [8 April, 1968], No. 12189/69. Heading D2A. A papermaking machine has a headbox with a pair of integral slice lips, and means for actuating the lips so that they vibrate at substantially their resonant frequency. This may be achieved by a mechanical coupling between one of the lips and a mechanical oscillator. Alternatively, the flow of liquid through the lips may be pulsated, e.g. by a transducer coupled to an electrical oscillator. In both cases, the oscillator may be adjustable as to its frequency. The headbox may also include an agitating roller. By energising the lips so that -they vibrate at their resonant frequency, flow through then is improved.
