摘要： The invention relates to a detector (D) for detecting when the thread bobbin in a thread-processing system (S) has to be replaced. Said detector comprises a movably received element (E), at least one detection member (7) that responds to a relative position or a relative position change of the element with a signal (i), and a power generator that exerts a force on the element, and the element (E) can be adjusted during the replacement. The force is oriented in the direction of movement of the element (E) towards the detection position (P). The positioning device is provided with a thread clamping area (6, 6') that is arranged relative to the path of travel of the element in such a manner that the positioned thread (Y), until the replacement, forms a barrier for the element (E) against a movement towards the detection position (P) in response to the exerted force. The thread, during replacement, becomes detached in such a manner that the element (E) automatically moves towards the detection position (P).

摘要： The invention relates mainly to a method for controlling the motion of a yarn stopper magnet in a measuring feeder for textile machines, preferably for weaving machines of air-or waterjet-type. The stopper magnet has a soft-iron armature connected to a yarn stopper element, which armature co-acts with at least one electromagnetic coil in order to achieve the desired motion of the stopper magnet. During an initial part of the time for the motion, according to the invention, said electromagnetic coil/-coils is/are supplied with a control voltage with an amplitude considerably exceeding the average level of the control voltage during the remaining part of the motion, in order to achieve an optimally fast motion with low input energy amount and thereby a low heat development, as well as low kinetic energy (speed) of the stopper element at the end of its motion.

摘要： The invention relates mainly to a method for controlling the motion of a yarn stopper magnet (2) in a measuring feeder for textile machines, preferably for weaving machines of air-or waterjet-type. The stopper magnet (2) has a soft-iron armature (16) connected to a yarn stopper element (13), which armature co-acts with at least one electromagnetic coil (8, 9) in order to achieve the desired motion of the stopper magnet (2). During an initial part of the time for the motion, according to the invention, said electromagnetic coil/-coils (8, 9) is/are supplied with a control voltage with an amplitude considerably exceeding the average level of the control voltage during the remaining part of the motion, in order to achieve an optimally fast motion with low input energy amount and thereby a low heat development, as well as low kinetic energy (speed) of the stopper element (13) at the end of its motion.
