ABSTRACT:
Paper trim, removed from a freshly made paper web by a slitter, is drawn by a subatmospheric pressure through a duct into a separating tank in which a suction is induced by a fan, the movement of the paper trim being killed by the circulation of pulp into this vessel from a mixing tank to which the slurry is delivered by a pipe from the bottom of the vessel. The pipe terminates in means forming a liquid seal and the solvent for the slurry is sprayed into the vessel to scrub the gas before it reaches the fan.
