For the optimization of the vacuum output of a suction air installation of a textile machine, the vacuum output is adjustably regulated by initially starting a batch with a predetermined vacuum for the vacuum demands under basic operating conditions and additional fluctuating working conditions, counting the errors which cannot be rectified and the attempts to rectify the errors caused by insufficient vacuum during a predetermined time period, subsequently changing the vacuum output of the suction unit during a subsequent time period, comparing the number of errors occurring under the changed vacuum conditions with the number which had occurred in the previous time period, and increasing the vacuum output when the number of errors exceeds a maximum predetermined amount of errors and decreasing the vacuum output when the number of errors is at or less than the maximum predetermined amount of errors.

The invention relates to a method and a device for preventing mass fluctuations in fiber material (1) which is processed in a spinning process using a rotor (10) to form a yarn (3). To this end, the mass fluctuations in the fiber material are detected in the immediate vicinity of the rotor and elements (6, 7, 12) which are drive-connected therewith, and are reduced by a control intervention.

A device is disclosed for damping the vibrations of a package on spinning, twisting or winding machines. Damping elements act on the swivel-mounted package holders, which damping elements are arranged on the machine frame and which are effective on the swivel direction of the package holders. The package holders are supported with tube sections on a swivel axle which is secured to the machine, and support the packages, which are pressed onto a driving roller and are rotatably supported thereon. In the swivel direction in which the packages are lifted from the drive roller, the damping is greater than in the swivel direction in which the packages are pressed onto the drive roller. The cylindrical outer contour of each individual tube section is surrounded, at a predetermined angle of contact, by a close fitting brake belt which is actuated by friction. One end of the brake belt is secured in a non-movable way on a stationary mounting, while the other end is secured to a loading spring. This loading spring tightens the brake belt in the swivel direction in which the package is lifted from the drive roller. As the rigidly supported end of the brake belt does not give, the damping effect comes into force immediately in the swivel direction which leads away from the drive roller. The counter-movement is, in contrast, hardly braked at all, as this slackens the brake belt.

Methods for optimally processing materials in a machine, such as a weaving machine, employing modular environmental control apparatus to control the conditions of gas flows sourced to or captured from various critical zones in materials processing machines. A plurality of processing performance parameters, part of which may respond differently to environmental conditions in one or more process zones, and thus may be in conflict with each other, are jointly controlled to yield maximum gross profit, to produce highest quality, to operate at highest throughput, etc., (but not necessarily simultaneously). One method includes the step of measuring at least one processing performance parameter, and at least partially controlling the processing performance parameter in accordance with a predetermined optimal control strategy by deliberately applying a gas flow conditioned by at least one controlling parameter, the gas flow being applied by a modular control unit. The disclosed embodiments are directed toward modular process zone environmental control in textile processing machines, both in yarn and fabric manufacturing processes, including weaving machines. However, Modular Process Zone Environmental Control (MPZEC) is applicable to materials processing in general.

An apparatus and method for reducing or preventing damage to a strand wound at relatively high speed on a machine-rotated spool, caused by flailing of a loose end of the strand includes capture brushes arranged at intervals in proximity to the machine. The capture brushes are aligned to be approximately perpendicular to the loose end of the strand when the loose end of the strand rotates with the spool into contact with the brushes. At respective ends, the brushes have respective tips with a taper that tends to guide or deflect the loose end of the strand to a slot defined by two adjacent brushes. The brushes have bristles extending from a bristle-mounting member, which capture the loose end of the strand. The bristles can be treated with a friction enhancing substance to improve the ability of the brushes to capture and entrap the loose end of the strand. Preferably, the bristles are angled with respect to the bristle-mounting member in a direction away from a respective tapered tip. As so angled, the bristles allow the loose end of the strand to pass relatively easily between adjacent brushes in one direction, but capture and entrap the loose end of the strand and prevent it from recoiling in the opposite direction out of contact with the bristles. A loose end of the strand is thus captured before it can damage the strand wound on the spool. After capture, as the spool rotates, the loose end of the strand is drawn through the bristles of the adjacent brushes in a direction approximately perpendicular to the bristle-mounting members. Thus, flailing or whipping of the loose end of the strand against the strand wound on the spool is prevented.

A bobbin winding machine includes a multiplicity of winding stations for rewinding spinning cops. Each of the winding stations has a bobbin magazine for holding the cops and a bottle-like unwinding chamber having a bearing shaft and an arbor being pivotable about the bearing shaft. The unwinding chamber surrounds a cop being fixed on the arbor during unwinding. At least a portion of the unwinding chamber is formed by a cop chute being pivotable between a cop transfer position and an unwinding position. The unwinding chamber has a shell partly encompassing a cop during unwinding.
摘要:
A method of and an apparatus for controlling the drive of a machine element of a spinning or twisting machine for exact positioning of the machine element at setpoint positions within a certain tolerance limit using motors which are not speed variable and are controlled by an on-off switch. The overshooting of the setpoint position can be detected and the measure of overshoot used as correction values for subsequent approaches to the setpoint position or to allow reverse approach to the setpoint with detection of overshoot beyond the tolerance and then a new approach with the iteration to a deviation less than the tolerance limit or a maximum number of cycles.
