Abstract
A closing member 1 for compressed air carrying polygonal tubes, which is inserted in a sealing manner into the polygonal tube at one end thereof. The closing member 1 includes an elastic sealing element 3, and the closing member is constructed such that it biases in its inserted state the sealing element 3 in such a manner that it seals and secures the closing member 1 relative to the polygonal tube 8. Closing members of this type are used to seal mounting tubes in yarn spinning machines with pneumatically loaded top roller support and weighting arms.
Claims19
A closing member for being inserted in a sealing manner in the end of a compressed air delivery polygonal tube on a yarn spinning machine, comprising an elastic sealing element, and with the closing member being configured such that it axially biases in its inserted state the sealing element, whereby the sealing element radially deforms so as to seal the closing member relative to the polygonal tube.
A closing member for being inserted in a sealing manner in the end of a compressed air delivery polygonal tube on a yarn spinning machine, comprising
- an end piece,
- a counterpart,
- an elastic sealing element disposed between the end piece and the counterpart,
- a threaded member interconnected between the end piece and the counterpart, whereby the threaded member is able to draw the counterpart toward the end piece and thereby radially expand the sealing element.
A mounting rod for the pneumatically loadable top roller support and weighting arms in a drafting system on a yarn spinning machine, said mounting rod comprising
- a pair of polygonal tubes of like cross sectional configuration positioned in an oppositely facing end to end relationship,
- a closing member disposed in each of the adjacent ends of the polygonal tubes, with each of the closing members comprising an end piece, a counterpart, an elastic sealing element disposed between the end piece and the counterpart, and a threaded member interconnected between the end piece and the counterpart, whereby the threaded member is able to draw the counterpart toward the end piece and thereby radially expand the sealing element, wherein the end piece, the counterpart, and sealing element are aligned along a central axis, and wherein the end piece and the counterpart have cooperating air passages which form a compressed air channel which extends off-center from said central axis through the length of the closing member,
- said closing members being disposed in an oppositely oriented relationship to each other and so that the end pieces are adjacent to each other and so that the compressed air channels are aligned, and
- a connecting tube interconnected in a sealed manner between the aligned compressed air channels of the adjacent end pieces.
