Definitions
- the present invention relates to textile machine units, and more particularly, to cots or roll covers for spinning rolls or other rolls used in the drafting or ,spinningof textile fibers. 7
- a textile Yroller as used in present day cottonand spinning machines comprises a metalcore or arbor having a sleeve-like roll cover known as a cot, surrounding theilcore.
- these covers have been made of leather, cork compositions, or certain types of rubber compounds especially adapted for this purpose.
- cork may be used as a roll covering or in admixture with rubber with a certain degree of success as a textile drafting material.
- the use of cork has been found to have certain disadvantages, among which are a certain degree of hygroscopicity, poor resistance to indenting or marking-as a result of the contact with the fibers, and a tendency to become slick and change its drafting properties after a period of use.
- Such cots are also-found to be affected by light resulting As a result, frequent grinding is necessary in order to renew the surface.
- Figure 1 shows a view in elevation partly in cross section of a conventional type of double cot mounted on an arbor.
- Figure 2 illustrates in cross section an enlarged view of a portion of the cross section of the cover shown in Figure 1.
- the double arbor is represented by 10, each side of the arbor having a roll cover 11 and 11a mounted thereon.
- the particles 13 which are embedded in the composition, are exposed at the surface of the roll and are also shown embedded in the roll compound 11 in Figure 2. 7
- the nut hulls are ground to a predetermined size and incorporated in the unvulcanized rubber compound in the desired proportions along with vulcanizing and other compounding ingredients.
- the mixture is then extruded in a tubular form, placed on a core, rag wrapped, and vulcanized.
- the rag wrap is removed and the resulting product ground down to the desired size. After this, the tube is cut to the desired lengths and the cots mounted on the arbor. A finish grind may be used before the cot is placed in operation.
- the preferred type of synthetic rubber with which this material is incorporated is an oil-resistant copolymer of the butadiene-acrylic nitrile type; also known as Buna-N, perbunan, GR-A, or by other well-known terms used in the trade. While the particle size and range of proportions of the nut shell material may vary considerably over a wide range, it has been found that certain particle sizes and proportions are of greater importance in obtaining optimum results.
- the particle size is generally preferred to be in the range of about 20 to 60 mesh, and the range of proportions is generally preferred to be a range of about 20 to 125 parts per parts of rubber by weight based on the rubber in the compound;
