Patent number: 5940925Abstract: The invention concerns a cleaning lip for a rotating roll of a textile machine in a rolling mill (1) for processing fibrous materials wherein the cleaning lip (9) is comprised of a combined carrying device and a lip, the length (1) of the lip (11, 23) being limited by a wiping edge (AK, AK.sub.1), and the lip is composed of plastic. On the lip (11, 23) and in proximity to the carrying device, a groove (12, 24) is placed which runs parallel to said wiping edge (AK, AK.sub.1) of the lip. Alternatively, the cleaning lip can be installed for the clearing of wrapping, in that, upon the roll (14) reversing its direction from an original direction, then the wiping edge (AK, AK.sub.1) of the lip (11, 23) swings itself out of its original roll surface contact position. Upon a subsequent change of roll rotation back to the original direction, the wiping edge (AK, AK.sub.1) also swings itself back to its original wiping contact position.Type: GrantFiled: September 30, 1997Date of Patent: August 24, 1999Assignee: Rieter Ingolstadt Spinnereimaschinenbau AGInventors: Wolfgang Gohler, Alfred Nauthe

Patent number: 4890359Abstract: The apparatus monitors lap formation at a pair of rolls guiding a slubbing or sliver in a drafting arrangement for spinning machines. In the event of a lap or coil forming, for example, on a pressure roll, a piston rod of a piston is shifted away until a switching element touches a contact edge or region of a switching sleeve. A cylinder housing encircling the switching sleeve and otherwise electrically separated from the piston is thus short-circuited with the piston. Since the switching sleeve and piston are separately connected to a control unit, a switching function is effected in the control unit by this short-circuit and the drafting arrangement is thereby stopped. The switching sleeve is slidably guided on a guide rod mounted at an upper part in such a manner that the frictional resistance is greater than the weight of the switching sleeve.Type: GrantFiled: January 9, 1989Date of Patent: January 2, 1990Assignee: Rieter Maschinenfabrik AGInventors: Beat Kagi, Peter Oswald

Patent number: 4785507Abstract: A retainer frame supportiing pat type clearer members is arranged in opposed relation to a draft roller. The retainer frame is inserted at both longitudinal end portions thereof into insert grooves of supporting brackets mounted on roller stands or draft roller bearing members placed on the roller stands. The retainer frame is formed by folding a metal plate. Each of the clearer members is formed with stopper lugs at both side edges thereof. With this arrangement, each clearer member may be easily installed into the retainer frame, and a uniform projection of the clearer member from the retainer frame may be maintained.Type: GrantFiled: July 21, 1987Date of Patent: November 22, 1988Assignees: Kabushiki Kaisha Toyoda Jidoshokki Seisakusho, Kanpatsu Kogyo Kabishiki KaishaInventors: Tsutomu Miyazaki, Yoshio Kawasaki, Kenji Negishi, Masao Wakai, Isao Ono, Isao Arita

Patent number: 4739540Abstract: In an apparatus for advancing a bundle of filaments, a pair of rolls defines a nip through which the bundle passes. A blower blows a stream of gas across an outer periphery of at least one of the rolls in a direction opposite the direction of rotation of that roll to dislodge adhering filaments therefrom. This prevents filaments from lapping the roll. The gas stream forms an obtuse angle with a radius extending from the point of intersection of the gas stream and the roll periphery.Type: GrantFiled: December 8, 1986Date of Patent: April 26, 1988Assignee: Celanese Fibers, Inc.Inventor: Ricky R. Hill

Patent number: 4677710Abstract: A cleaning arrangement for the pressing rollers of a combing machine which are pressed toward associated detaching rollers includes at least one cleaning roller which is mounted for free rotation in engagement with the respective pressing roller about an axis parallel to that of such pressing roller. The cleaning roller has a smooth outer surface to which fibers will not adhere. During the operation of the combing machine, the pressing rollers conduct controlled intermittent rotary movements, but the cleaning roller does not immediately follow such movements; rather, a certain degree if slippage occurs between the cleaning roller and the respective pressing roller, resulting in stripping off of any fibers which may adhere to the pressing roller.Type: GrantFiled: May 7, 1985Date of Patent: July 7, 1987Assignee: Maschinenfabrik Rieter A.G.Inventors: Hansulrich Eichenberger, Ludwig Lacher, Titus Schmid

-
Patent number: 4590647Abstract: In a textile machine, roller cleaning is carried out by means of a stripping knife, the front edge of which is pressed against the surface of the roller in the working position. The stripping knife, while maintaining its contact with the roller, is moved intermittently from this working position into a second working position in which the knife body touches the roller and the front edge of the knife is spaced apart from the roller. Fibers and impurities which have accumulated at the front edge as well as fibers jammed between the front edge and the roller are released as a result and are conveyed away by the roller thereby providing uninterrupted roller cleaning.Type: GrantFiled: October 1, 1984Date of Patent: May 27, 1986Assignee: Schubert & SalzerInventor: Max Fahmuller

Patent number: 4370781Abstract: There is provided a clearer device located above a series of draft rolls with a predetermined number of plumbs and secured inside a cover plate rotatable and removable by means of a pivot formed in part of two side plates. This clearer device is characterized in that endless clearer members stretch between intermittently driven clearer rolls and guide members permitting said clearer members to abut front top rolls fixedly secured. A pressure member is springingly held back of said clearer members to force downward said clearer members and permit said top rolls or a top apron to come into contact with said clearer members. The clearer rolls are intermittently driven by swinging a rocking lever pivoted on the shafts of said clearer rolls via an oscillation lever and rotating a ratchet gear fixed on said roll shafts by means of engaging tooth at said rocking lever.Type: GrantFiled: December 2, 1980Date of Patent: February 1, 1983Inventor: Yoshio Murao

Patent number: 4317261Abstract: An improved clearer for the drawing rolls, namely the top rolls, of spinning machines and like equipment. The clearer comprises a main frame or supporting structure for a clearing belt. The frame is pivoted adjacent the rear end of the apparatus. Carried by a portion of the frame are spring members which respectively press the belt into frictional driving engagement with a serrated roller forming part of the roll system and into clearing contact with one of the forward rollers which is to be cleared. The relationship of the parts is such that the belt also engages the upper surface of at least one other roller which is forwardly mounted relative to the roller just mentioned, to clear the same. Also, the clearer is provided with idler rolls for the belt which are located lower than the top of the cross member of the frame thus to reduce the overall vertical dimensions of the device and to get more "wrap" on the forward top roll, resulting in better clearing.Type: GrantFiled: June 9, 1980Date of Patent: March 2, 1982Assignee: Russell CorporationInventor: Fletcher D. Adamson

Patent number: 4028776Abstract: An intermittent drive revolving clearer for drafting rollers that moves to avoid the motion of a top comb thereby permitting continuous cleaning of the drafting rollers resulting in high efficiency cleaning and improved yarn quality. A knife edge removes the waste material from the continuous clearer cloth without mixing the clearer waste material with the sliver, thereby permitting continuous operation of the clearer for long periods of time.Type: GrantFiled: January 30, 1974Date of Patent: June 14, 1977Inventor: Yoshio Murao
