摘要： The invention relates to a thread gripper (G) comprising a stationary first gripping element (G1), which supports a thread clamping surface (K1), and comprising a mobile second gripping element (G2), which supports a thread clamping surface (K2). The thread clamping surfaces (K1, K2) can be pressed against one another with an adjustable contact pressure in a gripping position that holds the thread (Y) between the thread clamping surfaces. The thread gripper also comprises a setting element (S), which can be actuated out of a non-operative position by at least executing an opening movement, which can be brought into contact with the second gripping element, and which, at a time of thread release, adjusts the thread clamping surfaces over a thread release position until the thread gripper (G) is in an open position. In the gripping position of the thread gripper, an idle travel is provided between the setting element (S) and the second gripping element (G2). In the direction of the opening movement, said idle travel essentially corresponds to the travel path of the setting element during the acceleration phase thereof from the non-operative position up to an at least essentially constant speed and/or constant acceleration.

摘要： The invention relates to a thread detector (F) for detecting thread path/halt conditions and/or thread tension. Said detector is provided with a deflector assembly for re-directing the thread, said assembly transmitting the stress on the thread to at least one transducer device (W), which generates a signal and responds to mechanically transmitted stresses. The detector is also provided with at least one electronic evaluation circuit (6) for deriving output signals (i1, i2) and with thread guides (8), which are located upstream and downstream of the deflector assembly and define the course of the thread. The deflector assembly comprises a first and a second deflector (D1, D2) that lie one behind the other in the course of the thread, one of which transmits the stress from the thread tension and the other the stress from the path/halt conditions to a respective transducer device (W). The deflectors have first and second re-direction surfaces (9, 10), positioned transversely in relation to the thread axis, which together form an angle of

摘要： The weft thread (1) is drawn off the spool (2) with the aid of a thread store (3), whereupon it passes through a yarn tension device (4) and the inventive thread force sensor (5). The force that is exerted on the weft thread is measured in a manner known per se by deflecting said thread, whereby the reaction force (7) of the thread is converted by the pressure-sensitive element (6) into an electric signal (13). The electric signal (13) delivered by the thread force sensor (5) is electronically amplified in the evaluation unit (14) and emitted in the form of a signal (15) on a display (16) which is oriented by an operator during the course of the weft thread and makes the operator aware of disturbances and corrections thereof. The evaluation unit (14) is connected via a data line (17) to the machine control system (19) which supplies it with time signals for other machine functions, e.g. the momentary angle position of the main shaft of the machine, that are involved with said weft insertion. The machine control system receives monitoring signals from the thread force sensor via the data line (18), e.g. in order to bring about a sudden halt if the thread breaks during weft insertion or to activate a machine-related means of alarm in the case of a disturbance, thus requiring the intervention of an operator.

摘要： The invention relates to an actuator (A) for a component (2), comprising at least one defined stop position, in particular to a brake component actuator of a thread brake (B), for the selective braking of a running thread (Y) which has a drive organ (D) for linear or rotational adjustment of the component (2). Said actuator is provided with at least one stop device (C). The stop device (C) consists of an additional body (Z), supported in a displaceable manner on a motion damping device (F, G, H) which can carry out an adjustment. The actuator (A) in the thread brake is a reversible motor, suitably a magneto-electric motor (M) for rotational movement and an additional body (Z), supported in a displaceable manner on a motion damping device is provided in each stop device, in which the thread brake is to stop. During a linear adjustment of the component (2), the mass (m1) of the additional body (Z) matches the mass (m) of the displaced parts. In contrast, with a component (2) that can be rotatably adjusted, the moment of inertia (I1) of the additional body (Z) matches the moment of inertia (I) of the displaced parts, in relation to the axis of rotation.

摘要： The invention relates to a disk brake (B) for a thread (Y). Said disk brake has a run-in disk (E) which can be pressed against a stationary run-out disk (A) under the influence of a magnet (M), with a circular braking surface (2). The run-out disk (A) has a central run-out opening (16) for the thread (Y), which is braked between the braking surfaces (2, 14) which are oriented radially in relation to the brake axis (X). The run-in disk (E) is held in the nose area of a storage drum (D) of a thread storage device (F), in a manner that allows the disk to wobble, while the magnet (M) and the run-out disk (A) are held in a stationary support (S). The invention provides that the run-in disk consists of magnetic material and the magnet (M) acts on the run-in disk (E) magnetically through the run-out disk (A), so that the braking force that is exerted on the thread between the braking surfaces can be adjusted and varied.
