| titleOfInvention | Method and apparatus for doffing and drafting textile fibers |
| abstract | 946,694. Carding engines; mixing fibres. CHICOPEE MANUFACTURING CORPORATION. Feb. 17, 1961 [Feb. 19, 1960], No. 6037/61. Heading D1F and D1N. A fibrous web is doffed from a rotatable surface and simultaneously drafted by transfer from a first to a second surface rotating at a greater linear speed, the fibres being pressed on to the second surface close to the zone of transfer to prevent their return to the first surface. In a form of apparatus employing card fillet, a stripper roller 20 removes a fibre web from a doffer 12 and a roller 24 is arranged to press against the stripper roller 20 as close as possible to the periphery of the doffer 12. From the stripper roller 20, the fibrous web is transferred on to a conveyer belt 26 and then to a further conveyer belt 32. The speed of the belt 26 may be such as to provide conditions of draft or compaction. The ratio of the linear speeds of the roller 20 and doffer 12 may lie between 1.25:1 and 20:1 and the clearance between these rollers is from 0.005 inch to 0.15 inch. Metallic strip and clothing may be used on the rollers and in an embodiment described using such clothing the fibre web is transferred from the stripper roll by a smooth surfaced roller. Webs from several carding machines may be laid on each other and fibres shorter than customary textile lengths, say from # inch down to 1/16 inch or less may be added to the web. Examples of such short fibres are papermaking fibres such as woodpulp and wood fibres, cotton linters, cotton hull shavings, and mineral fibres, such as asbestos, glass, rock wool. Also other natural or synthetic fibres within the length ranges mentioned above may be used. The fibre webs themselves may contain cotton, silk, wool, vicuna, mohair, alpaca, flax, ramie, jute, cuprammonium, viscose, cross-linked cellulose fibres, cellulose acetate, cellulose tri-acetate, saponified cellulose ester fibres, polyamide and caprolactam fibres, protein fibres, halogenated hydrocarbon fibres, polyethylene, polypropylene, polybutadiene, polyisobutadiene, polyesters, vinyl fibres, dinitrile nitrile, acrylic and mineral fibres including glass and metal. |
