Patent number: 5184786Abstract: A method and apparatus for controlling the yarn tension of yarn being cross-wound onto a bobbin on a textile winding machine. The amount of yarn on a supply package from which yarn is unwound is determined optoelectronically, gravimetrically or by measuring the yarn tension. The winding speed of the bobbin is adjusted in response to the determined yarn amount of the supply package so as to maintain the yarn tension substantially constant during unwinding. The winding speed of the bobbin can be controlled to follow a predetermined winding speed program which corresponds to the determined mass of the supply bobbin. To determine the yarn amount gravimetrically, the supply package is weighed by a balance device as it is conveyed thereover by a conveyor. The movement of the balance in response to the mass of the supply package can be electronically transmitted to a control device which prepositions a cam having a profile corresponding to the predetermined winding speed program.Type: GrantFiled: December 3, 1991Date of Patent: February 9, 1993Assignee: W. Schlafhorst AG & Co.Inventors: Karl-Josef Brockmanns, Josef Derichs, Edmund Wey, Hans Grecksch, Leo Tholen, Manfred Lassmann

Patent number: 5104052Abstract: A method and apparatus are provided for separating a yarn end of a yarn package from the outer layer of the yarn package and disposing the separated yarn end onto the yarn package in a preferred disposition. The apparatus includes a drive device for rotating a yarn package in an unwinding direction, an assembly for performing a yarn end drawing out operation during the unwinding rotation of the yarn package and a device for determining that a successful yarn end drawing out operation has been performed including an assembly for detecting that a yarn end of at least a predetermined length has been drawn out. The apparatus also includes an assembly for controlling the drive device to stop the unwinding rotation of the yarn package in response to the earlier of the lapse of a predetermined period of time and the receipt of a signal from the detecting device indicating that a successful yarn end drawing out operation has been performed.Type: GrantFiled: March 27, 1991Date of Patent: April 14, 1992Assignee: W.

Patent number: 5090189Abstract: A method and apparatus for preparing a yarn package for a subsequent yarn restarting operation are provided. The apparatus includes an air jet for directing a tangential stream of pressurized air against a yarn package to effect loosening of a length of auxiliary yarn which has been wound on the yarn package during a prior unsuccessful yarn restarting operation in which the auxiliary yarn length failed to piece with the yarn still to be wound onto the yarn package. The air jet operates in cooperation with a suction conduit to completely unwind the unsuccessfully pieced auxiliary yarn length from the yarn package to thereby prepare the yarn package for receiving another length of auxiliary yarn during a subsequent yarn restarting operation.Type: GrantFiled: October 1, 1990Date of Patent: February 25, 1992Assignee: Zinser Textilmaschinen GmbHInventors: Edmund Wey, Manfred Anderheggen, Hans Grecksch

Patent number: 5022596Abstract: A method and winding apparatus for detecting feed bobbins having feed properties that do not correspond to a predetermined quality when winding feed bobbins onto cross-wound bobbins in an automatic bobbin winding machine is disclosed. The method comprises the steps of measuring the winding speed, counting yarn breaks before a predetermined threshold speed is reached for forming a yarn break count, detecting the quality of a given feed bobbin by comparing the yarn break count with a predetermined number and determining that the given feed bobbin has not attained a predetermined quality if the yarn break count reaches the predetermined number; if the quality is not attained, the given feed bobbin is rejected and the winding process is continued with a new feed bobbin.Type: GrantFiled: December 18, 1989Date of Patent: June 11, 1991Assignee: W. Schlafhorst AG & Co.Inventors: Edmund Wey, Hans Grecksch, Albert T. Pesch, Herbert Knors, Wilhelm Zitzen, Manfred Marquardt

Patent number: 4928895Abstract: A method and apparatus for transporting packages from stations of a textile machine to a location for further handling or processing includes a package support device. Packages are transferred from the winding station to the package support device and, when a plurality of packages are supported on the package support device, the package support device places the plurality of packages selectively onto one of a pair of package transport devices for transport of the plurality of packages from the stations to a location for further handling or processing. The package support device supports the plurality of packages at a clearance with respect to the pair of package transport devices sufficient to permit the package transport devices to transport packages therepast.Type: GrantFiled: March 30, 1989Date of Patent: May 29, 1990Assignee: W. Schlafhorst & Co.Inventor: Edmund Wey

Patent number: 4843808Abstract: Bobbins spun in a ring spinning machine are conveyed sequentially to a measuring, counting and sorting device located between the ring spinning machine and an automatic winder that winds yarn from the bobbins. The measuring, counting and sorting device senses the presence of a bobbin, counts the bobbins being sensed, senses yarn and bobbin characteristics and compares the characteristics with predetermined standards. The device separates bobbins whose characteristics differ from the standard. Data regarding the operation of the spinning machine and operation of the winding machine are combined with the data obtained by the measuring, counting and sorting device and statistically evaluated for display or for controlling the production of the spinning machine and winding machine or for controlling conveyance of the packages from the winding machine.Type: GrantFiled: April 14, 1988Date of Patent: July 4, 1989Assignee: W.
