PROCESS AND APPARATUS FOR MANUFACTURE OF PAPER YARN AND THE LIKE Filed Feb. 13, 1962 United States Patent 3,145,524 PROCESS AND APPARATUS FDR THE MANU- FACTURE 0F PAPER YARN AND THE LIKE Claude Hubert Augustin Dewelle, Eeklo, Belgium (a Rue du Nouveau Monde, Nivelles, Belgium) Filed Feb. 13, 1%2, Ser. No. 172,963 Claims priority, application Belgium Feb. 14, 1961 2 Claims. (Cl. 5758.49)
This invention relates to a new process and apparatus for the manufacture of paper yarn and the like from a ribbon or tape of paper or a similar material, in which a continuous length of tape is twisted.
Paper ribbons, such as kraft paper ribbons, as well as ribbons of other materials, such as synthetic resins or metals, such as aluminum, may be used for the manu facture of continuous yarns by the process according to this invention.
The starting ribbons or tapes may have any suitable width, in accordance with the thickness of the yarn to be manufactured. Usually, for manufacturing paper yarn from a kraft paper ribbon, the width of this ribbon is of about 0.2 to 0.5 inch. However, broader or narrower tapes may be used.
In the known processes for the manufacture of paper yarn and the like, a ribbon of paper supplied from a paper roll is subjected to a single twist in a device which may be a ring twister or a disc spinning twister.
These known processes have several drawbacks. One of these drawbacks is a relatively low production speed, due to the fact that the speed of the rotating spindles is limited. On the other hand, said known processes are not continuous.
An object of this invention is the provision of a process for manufacturing paper yarn and the like in a continuous manner and with a very high speed.
Another object of this invention is the provision of a process for manufacturing paper yarn and the like with a high uniformity.
According to this invention, a ribbon of paper or a similar material, supplied by a stationary stacking or pile of coaxial ribbon rolls is subjected to two successive twistings.
This double twist may be obtained in a double twister of the same type as the usual device used for the manufacture of yarns from textile natural or synthetic filaments or fibres. However, it is to be noted that the manufacture of textile yarns requires more than one step, whereas in the process according to this invention a single double-twisting of a continuous ribbon or tape is sufficient for obtaining the desired paper yarn.
In a particular embodiment of this invention, the ribbon is drawn through a rotating hollow spindle so as to be subjected to a first twisting, the partially twisted ribbon being then drawn out of said hollow spindle and caused to form a balloon so as to be subjected to a second twisting. The stacked stationary ribbon rolls are preferably maintained in such a position as to be coaxial to the rotating hollow spindle.
In order to enable the manufacture of a continuous yarn, the trailing end of one ribbon roll is attached, for example, by means of an adhesive to the leading end of the underlying ribbon roll in the stationary stacking of ribbon rolls.
The accompanying drawing given by way of example illustrates a device for carrying out the process according to this invention. p
The annexed figure is a diagrammatic view partly in section of a double twister by means of which the process according to this invention may be carried out.
The device comprises a cylindrical metallic box 1 3,145,524 Patented Aug. 25, 1964 containing a stacking or pile of paper ribbon rolls 2, said box 1 being maintained stationary by suitable means, such as a magnet 3. Each ribbon or tape roll 2 has a. central hole 4. A sleeve 5 fixed to the bottom 6 of the box 1 extends in the cylindrical space formed by the central holes 4 of the stacked ribbon rolls 2. The box 1 may be of any suitable material, such as synthetic resin, with an iron insert which cooperates with magnet 3.
A rotating hollow spindle 7 is engaged in the sleeve 5 through a hole 8 in the bottom of the cylindrical box 1, a ball bearing 9 being provided between the spindle '7 and the inner Wall of the sleeve 5. A disc 10 is fixed to the rotating spindle 7 under the bottom of the box 1. Under the disc 10, the hollow spindle 7 has a radial hole 12.
As shown by the dotted lines 11, the trailing end of each ribbon roll 2 is attached, for example by means of an adhesive, to the leading end of the underlying ribbon roll 2, so that it is possible to manufacture a great length of twisted yarn Without knot.
As shown by the drawing in which theribbon subjected to the double twisting in the device is indicated by 18, the leading end of the overlying ribbon roll 2 is drawn axially into the sleeve 5 and into the rotating spindle 7, the partially twisted ribbon runs out through the radial hole 12 and around the edge of the disc 10, then forms a balloon X, so that the twisted ribbon is subjected to a second twisting between the edge of the disc 10 and a stationary yarn guide or eyelet 13, so as to form a paper yarn which is drawn by a driving roller 14 and wound on the collecting roller 15.
The roller 14 is driven by a motor 16 through a transmission belt 17. The collecting roller 15 is driven by contact with the driving roller 14.
The speed of the rotating spindle 7 may vary between wide limits. This speed may reach 10,000 revolutions per minute, whereas with the known twisters used for the manufacture of paper yarn, the maximum speed of the spindles amounts to 4,000 or 5,000 revolutions per minute.
The process of this invention allows the manufacture of paper yarn on one machine in a single step, so as to provide a top quality yarn with minimum labour requirements. The process according to this invention allows a high production of paper yarn having a uniform structure and improved mechanical properties, namely a high tensile strength.
Comparative tests have been made and have shown the surprising advantages of the process according to this invention.
A paper yarn has been prepared from a kraft paper ribbon (weight: 40 g./m. having a width of 12 mm. The finished yarn had a thicknesscorresponding to 1800 meters per kilogram and a final twist of 4.1 t./inch.
Three samples have been prepared: one sample on a spinning frame type 4/4 of Carl Hamel Aktiengesell schaft of Arbon, Switzerland, the second sample on a paper twister model 4 of Saco-Lowell Shops, Boston, Mass, U.S.A., the third example on a double-twister as shown on the annexed drawing.
The following table gives a few results of the comparative tests:
