Patent number: 7684935Abstract: A device is disclosed for continuously cutting a fiber cable into sections, as well as a process for operating this device. The device includes a rotary knife carrier fitted with a plurality of knife blades, against which the fiber cable is pressed via a compression wheel. Wear and break of the knife blades are sensed by one or more structure-borne noise sensors. In addition, a characteristic parameter is formed from the signal from the structure-borne noise sensor(s) and compared with a comparison value. Deviations from the comparison value are recognized as disturbances.Type: GrantFiled: October 26, 2007Date of Patent: March 23, 2010Assignee: Oerlikon Textile GmbH & Co. KGInventors: Carsten Voigtländer, Matthias Strebe

Patent number: 7568262Abstract: A device and a method for serially depositing a filamentary strand into several cans of a can creel with a traversable depositing device. The depositing device comprises a conveyance means which is held in such a manner that it can be moved and which can be guided into several depositing positions. The strand is fed continuously to the conveyance means and from each depositing position at least one of the cans of the can creel can be filled by the conveyance means. In order to make the filling of a plurality of cans in the can creel as rapid and flexible as possible, the depositing device comprises a robot with a multi-axis robot arm, where the robot carries the conveyance means at the free end of its robot arm. Thus, the conveyance means can be guided, in its positioning as well as in its movements for filling the can, by the multi-axis robot arm of the robot.Type: GrantFiled: June 2, 2008Date of Patent: August 4, 2009Assignee: Oerlikon Textile GmbH & Co. KGInventors: Olaf Schwarz, Bernhard Schoennagel, Matthias Strebe

Patent number: 7279045Abstract: An apparatus for wetting an advancing filament bundle. A fluid is applied by means of a nozzle in the form of a fluid spray jet to the filament bundle advancing in spaced relationship with the nozzle. A portion of the spray jet is shielded before impacting upon the filament bundle, so that the application of fluid to the filament bundle is determined by the degree of shielding of the spray jet. With that, the invention is adapted for finely adjusting the fluid application to the filament bundle.Type: GrantFiled: April 18, 2006Date of Patent: October 9, 2007Assignee: Saurer GmbH & Co. KGInventor: Matthias Strebe

Publication number: 20070199281Abstract: An apparatus and a method for laying a tow into a can, wherein a tow feed device advances the tow into the can, with the tow feed device being movable to oscillate in a plurality of directions of movement. To obtain the highest possible flexibility when laying the tow into the can, the invention provides for moving the tow feed device by a multiaxial robot, which mounts the tow feed device at the free end of a robot arm.Type: ApplicationFiled: March 13, 2007Publication date: August 30, 2007Inventors: Bernhard Schoennagel, Olaf Schwarz, Matthias Strebe

Patent number: 7200521Abstract: A method and a device for detecting a fiber lap on a rotating machine component, wherein a sensor signal is used to detect the fiber lap that has formed on the circumference of the component. To enable a noncontacting monitoring despite unfavorable environmental conditions, the sensor signal includes ultrasound, and an echo sound signal is evaluated to detect the presence of a fiber lap. In one disclosed embodiment, the detecting device is used in association with a fiber cutting machine for cutting tow, and which includes a rotating cutting blade holder and a rotatable pressure ring, which cooperate for cutting the tow. To achieve a shutdown of the machine as quickly as possible upon formation of a fiber lap, the fiber lap is directly monitored on the circumference of the pressure ring by means of a sensor unit which has an ultrasonic transmitter and a sound receiver.Type: GrantFiled: January 4, 2005Date of Patent: April 3, 2007Assignee: Saurer GmbH & Co.

Patent number: 6758121Abstract: A device for cutting a fiber cable, in which a rotationally driven cutter supporting member and a rotatable pressing ring positioned at an incline relative to the cutter supporting member work together to cut the fiber cable. An annular channel formed on the outer circumference of the cutter supporting member is penetrated by a plurality of radially oriented cutting blades. The cutting blades are held in a cutter receiving member of a holding device, wherein a supporting ring radially supports the cutting blades. The width of the cutting blades is larger than the width of the annular channel. In order to consecutively use several areas of the cutting blades, the supporting ring is replaceable and is formed by an outer ring encircling the cutting blades or by an inner ring encircling the cutting blades. The cutting blades are held in the cutter receiving member and are radially moveable.Type: GrantFiled: September 12, 2002Date of Patent: July 6, 2004Assignee: Neumag GmbH & Co.
