Abstract: A method which improves the correspondence between the produced fancy yarn and the predetermined configuration of said fancy yarn. The fancy yarn is guided through a sensor device in a spinning device after it is formed and the diameter of the fancy yarn is continuously measured by the sensor device. The fancy configuration of the produced yarn is determined on the basis of the measured values of the diameter and is compared with the predetermined fancy configuration. The comparison is carried out until sufficient correspondence between the predetermined fancy configuration and the fancy configuration of the optimized, produced yarn is achieved.

Abstract: A yarn cleaner for cleaning defects from a yarn, by means of a head for measuring at least one yarn parameter for comparison against cleaning limits determined for the yarn parameter. If the cleaning limits are exceeded, a defect in the yarn is indicated whereby intolerable defects may be cut out from the yarn. The yarn cleaner is set up for cleaning an effect yarn, also called a novelty or fancy yarn, formed from an alternating thinner webs and thickened effects in the yarn. At least one value of the yarn parameter is predetermined for webs and for effects and the cleaning limits of the yarn cleaner are adjusted such that they lie outside the predetermined value of the web parameter and outside the predetermined value of the effect parameter.

Abstract: A yarn sensor for optically scanning a yarn (3), traveling longitudinally through a measurement gap (19), includes a light source (20) projecting a beam of light into the measurement gap (19), at least one receiver (23) for directly transmitted light, and light transmitting elements (24, 25, 26, 27) transmitting the light between the light source (20), measurement gap (19), and receivers (21, 22, 23). The light source (20) is an emitter with Lambert's emission characteristics. The light-transmitting element (27) includes a diaphragm and a lens, and the diaphragm is projected approximately into infinity. A diffusor (39) located between the light source (20) and the diaphragm generates radiation that passes through the diaphragm and is symmetrical to the optical axis of the lens. The yarn sensor can be used in the textile industry in spinning or bobbin winding machines with improved quality of the measurement results.

Abstract: A yarn sensor for textile spinning and bobbin-winding machines for optically scanning a longitudinally traveling yarn (3) within a measurement gap (19), particularly for detecting extraneous fibers, includes a light source (20), a first receiver (23) for directly transmitted light, two further receivers (21, 22) for light reflected from the yarn (3), and light transmitting elements (24, 25, 26, 27) between the light source (20), measurement gap (19) and receivers (21, 22, 23). In the absence of the yarn (3), the receivers (21, 22) detect projected images of the opposite wall (62) of the measurement gap (19), located essentially outside both sides of the area of the wall (62) of the measurement gap (19) illuminated by the direct radiation of the light-emitting diode (20). As a result, parasitic signals are suppressed, improving the detection of extraneous fibers.

Abstract: The aim of the invention is to create a method that allows a previously produced fancy yarn to be reproduced. Said aim is achieved by a method in which a model fancy yarn is first guided through a sensor device for measuring purposes, the diameter of the model fancy yarn is continuously measured using the sensor device, the measured diameter values are evaluated, and the formation of the effect of the model fancy yarn is determined therefrom. Spinning settings are generated from the data representing the formation of the effect, and said spinning settings, which are based on the set of data, are used for producing a fancy yarn.

Abstract: The yarn cleaner (5) is designed for cleaning out defects from an effect yarn (1), which is formed from an alternating stringing together of webs and of effects comprised of given thickenings. The yarn cleaner has a measuring head (6) in which at least one yarn parameter is measured, whereby cleaning limits are determined for the yarn parameter, and the presence of a defect in the yarn is signaled when these limits are surpassed. The measured values of the yarn parameter are compared with the cleaning limits and intolerable defects are cut out from the yarn. The cleaning limits are each dependent on whether the values are measured in the web or in the effect. The yarn cleaner (5) is suited for keeping the desired diameter quality of effect yarn on winding and spinning winding machines.

Abstract: A method and device for detecting foreign bodies in longitudinally traveling yarn (1), wherein light is directed on the yarn (1) and is reflected by its surface. Light reflected by the yarn (1) is detected by a sensor and is converted into signals. Subsequently, an evaluation of the signals is performed by comparing the signals with predetermined criteria which distinguish typical properties of foreign matter classified as tolerable, such as shell particles, from other foreign matter, such as foreign fibers, which are classified as not tolerable. Depending on whether these criteria are met, a decision is made whether a yarn interruption is suppressed or performed. In this manner, the efficiency of the production process of textile machines, such as spinning or bobbin winding machines, can be improved, and the uniformity and stability of the yarn are increased.
