摘要： The strip (2) of material - paper or fibre - is passed to a transfer mechanism from a roller or cylinder (1). It is then picked up, stretched and simultaneously moved at a higher speed than nromal, as a result of which a break is produced to form an end edge which can be easily blown over the transfer mechanism. This obviates double folding of the strip on starting or when a break in the strip occurs.

摘要： PCT No. PCT/FI90/00185 Sec. 371 Date May 31, 1991 Sec. 102(e) Date May 31, 1991 PCT Filed Jul. 24, 1990 PCT Pub. No. WO91/01810 PCT Pub. Date Feb. 21, 1991.A hydrocyclone apparatus is described for removing coarse particles, such as sand, metal chips, etc., from a fiber suspension liquid, whereby the apparatus separates coarser particles from the so called reject obtained from the cleaning process. The apparatus thus enables the reutilization of the reject, thus salvaging the remaining fiber material. The apparatus comprises a hydrocyclone installed in a cylinder, into which the reject flows out, with the entrained heavier and coarser particles, which settle out and are gathered at the bottom of the cylinder for discharge. The liquid rising in the cylinder flows through an overflow outlet to a separate side cylinder, which is open to the atmosphere, in which chamber further settling takes place. An inwardly extending pipe is arranged to extend in the reject nozzle of the cyclone from the upper portion of the auxiliary chamber. The reduced pressure condition therein extends through the inwards extending pipe, protruding into the auxiliary chamber, and liquid is drawn into the cyclone. The apparatus optionally may include several side chambers, which can be combined in series, one after another, for an improved cleaning process.
