Abstract
Description
- The present invention relates to a yarn brake, especially, a yarn brake for a two-for-one twisting spindle or a two-for-one twisting spindle machine, having a substantially tube-shaped yarn brake housing in which a capsule-shaped brake cartridge is arranged, the brake cartridge comprising first and second telescopically movableable tube portions which are movableable against the bias of springs. Each tube portion of the brake cartridge has a substantially ball or curve shaped end portion with the pair of end portions disposed oppositely one another for each cooperating with a respective fixed axial position brake and/or a resiliently biased, axially movable brake ring with the pair of brake rings being at an adjustable axial spacing from one another.
- Particularly in connection with the use of two-for-one twisting spindles, yarn brakes are known which comprise a yarn brake housing through which the yarn is axially trained. The inlet and outlet openings of the actual yarn brake region are respectively formed by brake rings having conical braking surfaces. The brake rings are typically comprised of a material having a high wear resistance. A brake cartridge, which forms the actual braking mechanism, extends between the individual inlet and outlet side of the brake rings and comprises two substantially cylindrical tube portions which are telescopically inserted into one another, and which include ball or curve shaped ends. The tubes enclose a spring which, upon the disposition of the brake cartridge in the yarn brake housing, outwardly resiliently biases the two tube end portions such that the curved-shaped ends of the tube portions are biased toward the brake rings and together therewith, as a function of the respective axial positions of the brake rings, exert the required braking force on the yarn traveling through the yarn brake. In accordance with the size of the required braking force, correspondingly stronger or weaker springs are disposed in the brake cartridge.
- To permit adjustment or, respectively, setting of the braking force, it is known from DE 43 43 458 C2 (corresponding to U.S. Pat. No. 5,581,988) and DE 44 08 262 C2 (corresponding to U.S. Pat. No. 5,487,263), to set the axial position of the upper brake ring or, respectively, the brake ring carrier which supports this brake ring, in selected different settings so as to thereby vary the axial spacing of the upper and lower brake rings from one another. In the yarn brake disclosed in DE 43 43 458 C2, the lower brake ring is disposed in a fixed axial setting in the yarn brake housing while the upper brake ring is axially adjustably mounted in the yarn brake housing to thereby effect adjustment of the braking force. DE 44 08 262 C2 further discloses that the lower brake ring or, respectively, its brake ring carrier, can be adjusted relatively against the force of a return position spring by means of a downward pressure exerted from the direction of the upper brake ring, so that the downwardly moving brake cartridge, which is urged downwardly under the influence of gravity, can be supported against support elements which project radially inwardly from the inner wall of the yarn brake housing. The brake cartridge thereby loses contact with the upper and lower brake rings so that a training or feeding of the yarn through the yarn brake is possible.
- It is an object of the present invention to provide simple and effective possibilities for altering the braking force.
- By adjustment of the guide conduit and, thereby, the corresponding positions of the spring biased support element supported thereon, a gross or rough adjustment of the braking force can be realized while, through corresponding positioning of the brake ring disposed in the yarn intake tube, a fine adjustment of the braking force is possible, in that the yarn intake tube is axially adjustable relative to the guide conduit.
- The object and advantages of the present invention will appear more clearly from the following specification in conjunction with the accompanying schematic drawings, in which:
- FIG. 1 is a sectional front elevational view of one embodiment of the yarn brake of the present invention for a two-for-one twisting spindle; and
- FIG. 2 is an enlarged perspective view of the yarn intake tube of a two-for-one twisting spindle.
- As shown in FIG. 1, the one embodiment of the yarn brake of the present invention includes a substantially cylindrical brake housing1, in whose interior is disposed a piston-type configured
brake ring 3 which is resiliently biased against an annular shoulder 1.2 by aspring 2 and which supports ayarn brake ring 4. Asupport element 5, which is cup-shaped, is mounted in the upper region of the brake housing 1 and is resiliently biased by a spring 6. Thesupport element 5 is secured to the lower end of aguide conduit 8, which extends upwardly in the brake housing 1, and which includes an upper end communicated with the exterior of the brake housing. The cup-shaped support element 5 is divided around its outer circumference into a plurality of support shoulders 5.1, 5.2, whose surfaces are axially offset from one another. By rotation of theguide conduit 8, a respective one of the support shoulders, such as, for example, the support shoulder 5.1, can be brought into seated disposition against a radially inwardly extending projection 1.1 extending from the inner wall of the brake housing 1. - A
yarn intake tube 16 is disposed in theguide conduit 8 and has, at its upper end, a flange portion 16.1 which extends in radially overlapping relationship over the upper end of theguide conduit 8 so as to thereby set the axial position of theyarn intake tube 16 within theguide conduit 8. A second yarnbrake ring carrier 15 is disposed at the lower end of theyarn intake tube 16 and supports or carries thereon a secondupper brake ring 14. Thebrake ring carrier 15 is disposed in the cylinder chamber 5.3 of the cup-shaped support element 5 so as to be axially displaceable relative thereto and is resiliently biased by aspring 17 extending therefrom against the bottom of the cylinder chamber 5.3. - As can be seen in FIG. 2, the upper edge of the
guide conduit 8 is formed with an angled surface on which aprojection 23, which is nose shaped, projects axially outwardly. The lower edge of the radially outwardly extending flange portion 16.1 of theyarn intake tube 16 is formed with an angled surface angled in correspondence with the upper edge of theguide conduit 8, and the circumference of the flange portion 16.1 is divided into a plurality of axially extending recesses ornotches 22, each of which has a bottom which is at a respective different axial spacing from the top of theyarn intake tube 16. - One can adjust the relative axial position of the yarn brake carrier within the cup-
shaped support element 5 by selective axial raising and turning of theyarn intake tube 16 so as to dispose a respective selected recess ornotch 22 in seated engagement with theprojection 23 formed on the top edge of theguide conduit 8. - A capsule shaped brake cartridge11 is supported between the
yarn brake rings movable tube portions 12 and 13. The lower tube portion 12 is substantially in the form of a cylindrical tube and includes a lower curved or arcuate end portion. Theupper tube portion 13 is, as well, configured as a cylindrical tube and includes, in its middle or central portion, an outwardly flared portion 13.1 and, at its upper end, includes a ball or curve shaped end portion. - In connection with the brake cartridge, the brake cartridge includes a conventional construction element in the form of a spring disposed interiorly thereof whose resilient biasing force can be opposed so as to move the two
tube portions 12 and 13 toward one another. - To produce the braking force in connection with the yarn brake of the present invention, springs within the brake cartridge11, on the one hand, and springs for respective positioning or, respectively, axial movement, of the two
brake rings shaped support element 5, a gross or rough adjustment of the braking force can be adjustably set while, through corresponding positioning of theupper brake ring 14, a fine adjustment of the braking force is possible, in that theyarn intake tube 16 can be adjustably axially positioned within theguide conduit 8. - If, for the purpose of training a yarn through the yarn brake, the
lower brake ring 3 is biased against the force of thespring 2 in a conventional manner such as, for example, in a pneumatic manner, thelower brake ring 3 is displaced downwardly such that the brake cartridge 11 can move relatively within the brake housing 1 and a plurality of radially inwardly extendingsupport elements 20 support or, respectively, catch the brake cartridge 11, in that thesesupport elements 20 engage the radially outwardly extending portion 13.1 of the brake cartridge. - The specification incorporates by reference the disclosure of German priority document 100 32 141.0-26 filed Jul. 1, 2000.
- The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawings, but also encompasses any modifications within the scope of the appended claims.
