Specification of Letters Patent.
Patented Sept. 27, 1921.
Application filed March 26, 1918. Serial No. 224,873.
T 0 all whom it may concern Be it known that I, FRIEDRICH PAUL PRIEM, subject of the King of Saxony, residing at Heidenheim on the Brenz, in the German Empire, have invented certain new useful Improvements in a Machine for Producing Rovings from Paper-Pulp, for which I have filed application in Germany, March 19, 1917, v. 137% VII/76c, and of which the following is a specification.
For the production of rovings from paper pulp rubbing rollers or rubbing bands have been used, which bring the paper strips, partly deprived of their water by the aid of couch rolls or roller presses, into a round form. These rubbing or rounding devices follow the usual delivery roll or even the roller presses directly. Consequently it was only possible to make use of a very small number of rubbing devices, so that there was merely a way for making coarse yarns from comparatively broad strips of paper fibers and moreover there was this drawback that in using more than two rubbing or rounding devices, the intermediate third rubbing device was not accessible. This drawback was particularly inconvenient, when rubbing bands were used.
To do away with these drawbacks, according to the present invention, a special distributing roll is arranged intermediate of the usual delivery roller and the rubbing devices. This distributing roll is made in a comparatively large diameter, thus enabling a large number of rounding devices to be used in connection with this distributing roll, also enabling these rubbing devices to be placed at a considerably large distance from one another, so that every rubbing device is suflicient accessible for handling and leading the stripsv to the rubbing devices. By this invention itis also possible to produce very fine yarns, since the breadth of the press rollers can be divided into correspondingly finer divisions.
In the drawing a machine is shown diagrammatically constructed according to this invention.
The narrow fiber or paper stuff strips produced on a wire apron a are taken onto the endless upper felt Z; by the couching rollers a 6 around the upper roller 6 of which the felt I) is led. In order to free the paper strips of their water to a greater extent, they are led by the upper felt Z) to the felt press c, Z2 around the lower roller 0, of which the endless felt 03 runs and is guided by the rollers'al, d d (Z 65 The paper strips thus free of water adhere to the upper felt I and from this they are led to the distributing drum or roll 6, against which they are pressed by the roller 5 whereby they are loosened from the upper felt I) and transmitted to the roll 0. From here the upper felt Z runs back to the pressure roller 12 after passing the rollers 6 b b 19 The strips now are carried along by the roll 6 and led to the rubbing 0r rounding devices g g g 9 which are distributed about the lower part of the roll 6. The strips are distributed on to the rounding devices in groups 7, f f f so that the different strips led to the divers rubbing devices are spaced to a distance requisite for proper rounding. The fiber strips rounded by the rubbing devices are wound up in the reeling devices 72, h 71 ]L4 on separate spools which are to be further treated according to requirement in some other machine.
Paper pulp fibers or parts of the same, which adhere still to the roll are taken off by scrapers c' and fall down on a gathering trough 73 arranged below.
The number of rubbing devices and the reeling devices can be chosen corresponding to the number of paper strips.
We claim:
1. In a machine of the character described the combination with means for forming and conveying strips of wet paper stock; of a distributing drum of large. diameter and a plurality of rubbing devices to roll said strips into rovings, said drum presenting a circumference large enough to maintain said rubbing devices spaced sufliciently for access between them of workmen.
2. In a machine for making paper rovings the combination with means for forming and conveying narrow. paper strips, a distributing drum of large diameter, means to transfer the strips from the conveying means to said drum; roving forming devices arranged below the horizontal diameterof the drum and spaced sufficiently apart to permit access thereto, the peripheral extent of said drum being sufficient to permit such spacing.
' v 3. In a machine for making paper rovings sufiiciently'from the drum to permit at least the combination with means for forming and partial gravitational separation of the strips conveying narrow Wet paper Webs; of a plufrom the drum n on assin to said devices. 10
rality of devices for forming roving from FRIE RI H PKUL PRIEM. said strips arranged beneath said drum, Witnesses: spaced from one another suflicient to permit WILHELM MAIER,
access of workmen between them, and spaced PAU Rmorr.
