摘要:
The thread delivery device (1) according to the invention has a holding rail (11), in or on which a transfer element (34) is mounted movably. Said transfer element (34) detects actuation of at least one of a plurality of thread sensors (17) in an equal and preferably magnetic manner. The thread sensors (17) can be arranged in any desired position and number on the holding rail (11). The transfer element is deflected from its rest position when one of the thread sensors is actuated, that is to say its thread sensor lever moves into the actuated position. The deflection of the transfer element is detected by a switching device (42) and can be indicated by way of a signal lamp (15).

The invention relates to a thread feeding device (1) comprising one or more thread detector levers (26) which are arranged in displaceable manner in a housing (2). The thread detecting lever (26) is displaceable between an operating position I and a response position II. In the operating position I the lug thereof (28) which forms the means for detecting the thread, is approximately aligned with the thread guiding element, for example the lugs (19, 23) of the thread guiding members (18, 22). Approximately upstream from the operation position I, the thread detecting device (26) encounters the stop thereof beyond which it can no longer be displaced by the thread (8). In order to improve the accessibility to the thread guiding elements (19, 23), particularly when inserting and threading threads, the thread detecting lever (26) stop is elastic. The lower end (28) of the thread detecting lever (26) can be displaced manually in an upward direction beyond the stop in order to create a free space between the thread guiding elements (19, 23).

The inventive bearing system consists of a bearing seat (21), a roller bearing (18), and a squeezing element (26). The squeezing element lies flatly on the outer ring of the roller bearing and only in areas on corresponding areas of the bearing seat. The areas are preferably linear or strip-shaped and are oriented in an essentially axial manner. This facilitates the insertion and removal of the roller bearing (18) into or out of the bearing seat (21) and prevents the outer ring of the bearing from being rotated along, also in the case of bearing seats that are provided with relatively generous tolerances.

The invention relates to a yarn tension device (1), comprising tensioning means (21, 22) which are independently adjustable and cooperate with braking actuators (8, 9). In contrast to conventional yarn tensioning devices the desired position of the braking actuator (8, 9) may be achieved by adjustment of both tensioning means (21, 22). A desired centre position for each thread tension may be achieved, for example. It is also possible by means of the direct adjustment of both tensioning means (21, 22) to shift the centre position. The adjustment of the yarn tension is thus separate from the adjustment of the centre position.

A thread delivery device (1) according to the invention for feeding a thread to a textile machine is provided with a thread delivery wheel (3), with a drive shaft (4), the axis of rotation of which extends vertically in operation and on which the thread delivery wheel (3) is disposed, and with a beam (5) for supporting the drive shaft (4). The thread delivery device (1) has at least one thread sensor (11, 12), a first and at least one second thread brake (16, 40, 17, 30, 41) in the thread path before the thread delivery wheel (3) and a knot catcher (18). According to the invention a knot catcher (18) is disposed between the two thread brakes (16, 40, 17, 30, 41).
