摘要： A method of and apparatus for stabilizing the fabric within the weft beat-up area in multiple-shed weaving machines or wave weaving loom wherein the beat-up is effected by means of a rotary reed. Immediately after the weft has been beaten-up, the fabric passes through a stabilization slot, and after having passed therethrough, it changes the direction of its movement beyond the level of the weaving plane.

摘要： An open-end spinning machine, is operated by continuously advancing a yarn towards a take-up station at which it is wound onto a bobbin rotating at a predetermined speed, so that a yarn package forms on the bobbin and the latter eventually becomes full. As the bobbin approaches a condition of fullness, an empty bobbin is rotated adjacent to it and is accelerated until it reaches the speed at which the full bobbin rotates. The yarn which advances onto the full bobbin is then severed from the yarn package on the latter, to provide a free yarn end which is inserted into one axial end of the rotating empty bobbin, to be engaged and entrained by the latter whereby winding of the free yarn end onto the empty bobbin commences. The full bobbin is now removed from the station and is replaced with the rotating empty bobbin.

摘要： This invention relates to an apparatus for emergency fiber supply to a spinning unit in an open-end spinning machine. According to the invention, a sensing unit controls an electromagnetic coupling and fiber supply device, such that a break in the yarn is rapidly detected and the fiber supply is immediately disengaged, even if the conventional thread breakage detector fails.A sensing unit is disposed in that portion of the wall of a cover that extends into the spinning rotor interior. It is adapted to respond to the excess accumulation of unspun fibers and/or an undue increase in temperature by disconnecting the electromagnetic fiber supply coupling via the thread breakage detector circuit to which it is connected. The sensing unit can be a pressure sensitive microswitch, a bimetallic relay, a thermistor, or a combination of these elements.

摘要： Method of and apparatus for spinning yarn of staple fiber in an air vortex in a spinning tube. Separated fibers are withdrawn from the spinning tube in counterdirection to a whirling flow of air produced in a pneumatic chamber coupled to the spinning tube. The yarn being built is twisted in the pneumatic twisting chamber by means of concentric air streaming producing an excited potential air vortex about the longitudinal axis of said pneumatic twisting chamber and about the yarn passing therethrough.The apparatus is characterized in that a surface of revolution defining the cavity of said chamber is formed by a peripheral surface on which at least one duct opens for supplying pressure air and which merges into lateral surfaces which, beginning from the widest portion of said peripheral surface, converge up to a distance of a gap between an outflow aperture of an outflow tube and an outflow aperture of a yarn take-off tube. Said lateral surfaces are inclined to each other and to the longitudinal axis of said chamber, said inclination producing in the chamber interior a concentric air streaming producing an excited potential air vortex about said longitudinal axis of the chamber.

摘要： Method of and apparatus for cooling the spinning units of open-end spinning machines driven by individual high speed electric motors. A cooling air flow is separated from the technological air flow, such cooling air flow being introduced into the housing of each unit in the space between the rotor of its motor and the spinning rotor connected thereto and dividing into two flows. One such flow travels between the stator and rotor of the motor; the other flow travels within the unit housing radially outwardly of the stator of the motor.

摘要： An improved arrangement of leno discs on axially opposite sides of the main fabric beat-up discs of a rotary reed is described. Three leno discs are provided in each set, with the channel between the innermost and intermediate ones of the discs in each leno set being established by an adjustable spacer to form the required warp-free zone between spaced bundles of the leno warp threads guided by the leno discs. The innermost disc of each set is identical in construction with the outermost disc, with the intermediate one of the discs differing from the other two only by exhibiting a peripheral warp-confining chamfer which is complementary to that of the other two discs. The chamfer of the intermediate disc is disposed on the reed shaft in axially opposed relation to the chamfer of the innermost disc.

摘要： A method of separating fibers from a fibrous sliver and conveying them in this condition to a twist forming element of an open-end spinning unit. The fibers traverse a fiber separating zone which is formed by the annular space between a combing-out cylinder and the bore of a housing. Ambient air is sucked into this fiber separating zone as well as into a sliver feeding zone. The air being sucked in is the resultant of air flowing in planes perpendicular to the axis of the combing-out cylinder, in planes passing through said axis and in planes parallel to said axis.The apparatus for carrying out the aforedescribed method which includes a housing with a bore, a combing-out cylinder coaxially mounted in the bore, a sliver feeding device mounted in a cavity of the housing adjacent to the combing-out cylinder, and a lid covering the housing, but at least the region of the sliver feeding device being at least partially exposed to permit ambient air to be sucked into the sliver feeding and fiber separating zones.

摘要： The invention relates to an open-end rotor spinning unit and particularly solves the problem of the relationship between a fiber defining stud of a separator, a fiber supply duct and a yarn take-off duct passing through the separator and the stud.According to the invention, there is established a dimensional relationship of the defining stud to the mean staple length of fibers, and the orientation of the supply duct at an acute angle to the front wall of a cylindrical projection partially engaging into the spinning rotor.In inner section of the peripheral wall of the defining stud is curved in the direction of a natural fiber flow trajectory into the direction of the spinning rotor rotation while the outer section is either in contact with or radially set back from the cylindrical wall of the projection at a distance of up to 4 millimeters from the edge of the wall.
