Applioatioii filed January 23, 1925. Serial No. 4,249, and in Germany January 28, 1824.
My invention relates to paper making machines and it is an object of'my invention to provide a machine of this kind in which the rails of the shaking frames are divided and are shaken differently.
In the new machine the Fourdrinier wire or wire cloth is so guided by clamping means arranged at a short distance from the connection of those rails which are shaken difi'erently that the wire cloth is compelled to follow the shaking motion of the rails. Preferably,-these means comprise a roll arranged below the wire cloth and extendingacross the entire width thereof, and two comparatively narrow rolls 12 which only engage the marginal portions of the wire cloth so as not tointerfere with the pulp which passes between them. Y
In the drawings affixed to this specification'and forming part thereof, a machine embodying my invention is illustrated diagrammatically by way of example.
In the drawings Figs 1 and 2 are a diagrammatic elevation and plan view, respectively,
Fig. 3 is a cross-section on the line 33 in Fig. 1, viewed from the left, and
Fig. 4 is an elevation of the clamping device, both the last figures being shown on a larger scale.
Referring to the drawings, the Fourdrinier wire or wire cloth, 4 moves in the direction of the arrows in Figs. 1 and 4 and is supported by table rolls 3 which are carried on frames constituted by pairs of register bar-s1, 1 and 2, 2, the register bars being connected by pins 15 or othersuitable means and made tubular in order to save weight.
The front register bars .1, 1 are shaken in parallel and may be connected by transverse and diagonal stays in the usual manner said front register bars being reciprocated by means of a device generally indicated at 1'. The rear bars 2, 2 are arranged for rocking motion about pins 9- and 10 on brackets 5, 5 as indicated in dotted lines, so as to effect the compensating shak-- ing motion.' Preferably the registering bars 2 are connected bv transverse stays, which however must be pivoted to the bars so as not to interfere with their rocking motion. Pul is delivered to the wire cloth 4 from a device comprising the usual deckle strap 14 and a wire cloth 15 which delivers the pul to the Fourdrinier wire 4 at the front en of the machine.
The clamping device as shown in Figs. 3, 4. comprises a roll .11, preferably a solid rubber roll, which rotates about trunnions 11, 11 carried in the rails 1, 1 and narrow rollers 12, 12. above and on either side. of the sieve 4, the shaft 13 of which is carried in bracketsl3' secured to the rails 1 as will be seen in Fi 4. The pulp 14 is narrower than the wire cloth so that the rollers 12 do not interfere with it.
The novel clamping device effects a good transfer of the pulp from the frame 1, 1 which is shaken in parallel to the rocking frame 2, 2 the wire cloth being compelled to partake in the motion of the rails. This prevent undesired deviations of the wire cloth which would interfere with the action of the suction boxes. Consequently in my novel machine .the water marks will be clearly defined in any part of the pulp.
I wish. it to be understood that I do not said wire cloth along said frames, means for imparting tosai frames different shaking mot-ions and means carried on oneof said frames for positively connecting said wire cloth to said frame, said connecting means being'arranged at a short distance from the connectionof said frames.
2: Paper making machine comprising a wire cloth, pivotally connected shaking frames, means for supporting and guiding said wire cloth along said frames, means for imparting to said frames different shaking motions, said means comprising a roll extending'all over the width of said wire cloth and adapted to rotate in contact with one side of said wire cloth and a pair of concentric rolls adapted to rotate in contact with the other side of said wire cloth, said roll and said concentric rolls being arranged -on one of said frames and said concentric .rolls being spaced apart a distance substantially equal to the width of the web of paper pulp on said wire cloth. I
In testimony whereof I affix my slgnature.
PAUL ERKENS.
