摘要:
A texturing machine for draw texturing a plurality of synthetic multi-filament yarns and which includes a plurality of side by side processing stations. Each of the processing stations comprises a plurality of processing units for advancing, texturing, drawing, and winding the yarn. At least one of the processing units is driven by an electrical individual drive, with the individual drives of the processing units of adjacent processing stations being controlled by a common group frequency changer. To enable a separate connection and disconnection of the individual drives with a simultaneous group control, the electrical individual drive of each processing unit includes an asynchronous unit and a synchronous unit. In the case of a predetermined desired frequency, this permits an automatic startup and maintenance of the desired frequency, which leads to a high degree of uniformity of the yarn treatment in each processing station.
摘要:
In a method for operating an internal combustion engine, a computer program product, a computer program, and a control and/or regulation device for the internal combustion engine, the internal combustion engine is allowed to be operated using an enriched air/fuel mixture, without exceeding a rich combustion limit of the internal combustion engine. In the process, a setpoint value for a variable characterizing the air/fuel mixture is specified in at least one operating state of the internal combustion engine. A value of at least one variable characterizing the quality of combustion is determined. The determined value for the at least one variable characterizing the quality of combustion is compared to a first specified threshold value. If the determined value for the at least one variable characterizing the quality of combustion deviates from the first specified threshold value by an amount that exceeds a second specified threshold value, then the setpoint value is corrected.

摘要:
A method and apparatus for controlling a machine for false twist texturing a plurality of synthetic filament yarns and which includes a plurality of side by side processing stations. The plurality of processing stations are divided into a plurality of sections, with each section comprising a plurality of processing stations. The processing stations of each of the sections are monitored and controlled independently of the processing stations of adjacent sections, so that the processing of the yarns in each section is independent of the processing of the yarns in adjacent sections.
摘要:
A cable transport device having a pivotably mounted cable transporter, a first drive means connected in a stationary manner to a base frame and intended for achieving an exactly defined pivot movement of the cable transporter around a pivot axis and a second drive means for synchronous driving of at least two cooperating pressure rollers. The second drive means with a drive axle for the pressure rollers is connected in a stationary manner to the base frame, and the drive axle of the second drive means coincides with the pivot axis for the cable transporter. The transmission of the pivot movement is effected via a toothed belt which is tensioned symmetrically to the center of rotation of the pivot axis between a first intermediate shaft arranged on a base plate of the cable transporter and a second intermediate shaft fixed to the machine frame, the pitch axis of the cable transporter being identical to the axis of the first intermediate shaft.
摘要:
A texturing machine for crimping an advancing yarn and which includes a plurality of processing units and a plurality of feed systems. At least one of the feed systems is formed by a driven feed roll and a rotatable guide roll mounted in cantilever fashion on a machine frame, and about which the yarn is looped. A threading device is associated with the rolls for an initial threadup of the yarn before the start of the process, and by which it is possible to lay the advancing yarn against the circumference of the rolls with a total looping greater than 360°.

A yarn false twist texturing machine for texturing multifilament synthetic yarns (4), wherein a heating device and a false twist unit are arranged within a false twist zone. An aftertreatment zone accommodates a second heating device and a countertwist device. The countertwist device is used to remove any residual twist that is left in the yarn by the false twist unit. To be able to perform a selective treatment by the countertwist device, a first embodiment provides for a twist imparting member yarn guide means for guiding the yarn (4) and being adapted for reciprocal movement between an idle position for not treating the yarn (4) or for threading it and an operating position for treating the yarn (4). In a second embodiment, the countertwist device comprises a movable twist imparting member (28, 29), which is adapted for reciprocal movement between an idle position for not treating or for threading the yarn (4) and an operating position for treating the yarn (4) by twisting it.
