摘要： A yarn processing system (T) consists of a yarn feeding device (F) and an accessory device (Z, Z1, Z2, Z3) associated to the yarn feeding device (F), said accessory device comprising a device part (K, M, 4) which is driven using a signal representing the rotational speed of a component of the yarn feeding device. Said signal is generated by an electronic sensor (S) galvanically separated from the control system (C) and the drive means (M) of the yarn feeding device (F). Said sensor (S) also is structurally independent from said yarn feeding device (F). The sensor is located at or close to the yarn feeding device (F) at a mounting location (X, X1) where a part of a rotating magnetic field is detected by said sensor at the mounting location. Said part of the magnetic field originating from inside of the yarn feeding device is not used for the operation of the yarn feeding device at the mounting location of the sensor (S). The sensor comprises a pick-up head responding to said part of the rotating magnetic field which part is present at the location of the sensor but is not used for the function of the yarn feeding device at said location.

摘要： The invention relates to a method for intermediate storage of threads (Y) on a drum-like storage body (4) of a delivery device (F) in which the thread is placed on the storage body (4) by means of an electrical winding drive mechanism (3) with relative rotational movements between a winding element (2) and a storage body interrupted by stationary periods (C). During each stationary period (C), one holding torque (H) operating in the winding direction is electrically generated in the electrical winding drive mechanism (3). An electromotor device (D) for blocking reverse rotation is provided in a delivery device for carrying out said method. Said electromotor device (D) can be activated by a holding current during each stationary period (C).

摘要： The invention relates to a supply device (F) comprising a thread measuring function for a loom, said device being provided with a stationary, narrow-diameter storage body (K), to which a first pin-type stop element (S1) is allocated. Said element can be displaced in an essentially radial and axial direction in relation to the axis (X) of the storage body in order to perform a thread measuring function and to stop the respective take-off of a section of thread. A second pin-type stop element (S2), which is displaced exclusively back and forth in an essentially radial direction relative to the axis (X), between an engagement position and a passive position, co-operates with the first stop element (S1) in order to initiate the corresponding thread take-off and to receive the wound thread that has been measured by the first stop element (S1). Both stop elements (S1, S2) lie adjacent to one another and are offset in the axial direction and/or in the peripheral direction of the storage body.

摘要： The invention relates to a pneumatic thread tensioner (T) for a gripper shuttle loom or a knitting machine, in which the air-current deflection surface (19) for deflecting the thread (Y, Y1) forms a seamless extension (12) of the inner wall of the linear guide channel, through which the thread runs. The invention also relates to a device (H) for changing the flow rate or the pressure of the air-current along the deflection surface (19) of the pneumatic thread tensioner (T) between at least two different levels, in accordance with the operating cycle of the textile machine.

摘要： The invention relates to a monitoring device for the weft thread of a mechanical weaving loom, comprising at least one weft element having a thread clip which can be moved into a thread release position, and a weft thread detector monitoring the movement of the weft thread. Said detector is only activated during an observation interval for each weft, said observation interval ending at least approximately with the release of the inserted weft thread by means of the thread clip. An electrical sensor (S) which responds to the release position of the thread clip by means of a signal (I) representing the end of the observation interval is provided in an opening device (B) arranged in the mechanical weaving loom for the thread clip (G) of the weft element.

摘要： The invention relates to a method for inserting weft thread material, comprising an insertion system in a power loom. According to the inventive method, for every insertion the insertion system (A) is supplied with a substantial part of the weft thread required for the insertion in a loose and substantially tension-free manner so as to be intermittently pulled off. A tubular batch of adjacent windings is produced from the weft thread material on an inner mechanical support (S) by way of an at least substantially continuous winding process and is conveyed forward in the direction of pull-off. For the purpose of pull-off, a number of windings that corresponds at least approximately to the weft yarn section is detached from the support while maintaining its tubular configuration and is substantially slackened. The weft yarn material is pulled off along the tubular axis (X).
