Apparatus for applying pulp to a conductor with a control to operate an adjusting means to vary the amount of pulp fibre in a pulp bath dependent upon signals received corresponding to weight of pulp applied to the conductor whereby the weight is controlled within preset limits. Another requirement is an oven with at least two zones and a moisture measuring and diameter measuring means for pulp issuing from the oven, the latter means controlling the oven zone temperatures to provide a controlled degree of pulp expansion during flash evaporation and a controlled moisture retention in the dried pulp.
