The yarn feeder device () of the invention has one or more yarn feeler levers (), which are movably supported on the housing (). The yarn feeler lever () is movable between an operating position I and a response position II. In the operating I, its crossbar () which forms the yarn feeler means is approximately in the same line as yarn guide elements, such as the struts () of yarn guide bails (). Somewhat above its operating position I, the yarn feeler lever () meets a stop, past which it is not moved by the yarn (). To improve the accessibility to the yarn guide elements () particularly when yarn is being inserted and threaded in, the stop of the yarn feeler lever () is embodied as yielding. The yarn feeler lever () can therefore be moved upward manually past the stop on its lower end (), in order to open up the space enclosed between the yarn guide elements ().

Thread feeding device comprising a spring stop for thread detectors

The bearing device is formed of a bearing seat, a roller bearing, and a squeeze element. The squeeze element rests over a large surface area on the outer ring of the roller bearing and rests only regionally on corresponding regions of the bearing seat. The regions are preferably linear or striplike and are oriented substantially axially. This facilitates the insertion and removal of the roller bearing into and out of the bearing seat and prevents rotation of the outer bearing ring even if the bearing seats are provided with relatively generous tolerances.

Bearing system, especially for yarn feed devices

A yarn brake having two disklike or platelike brake elements pressed resiliently against one another has a substantially U-shaped bail (19) with two legs extending in spaced apart fashion an either side of the brake elements. Pinlike bearing means for the brake elements are secured to this bail by means of at least one bearing part receiving them, which part is embodied on or joined to at least one of the bail legs. At least one of the brake elements has a central opening, through which the bearing means extend.

Yarn brake

A plate-type thread brake includes two brake elements pressed resiliently against each other by a load device and receiving the thread passing through between them. These brake elements are eccentrically suspended on bearings on the inside wall of a central opening which only fill out a small part of the opening. Thread guides are also arranged in the region of this central opening.

Thread brake

A yarn brake has two brake disks, retained with axial play in a support or bearing device, which are retained against one another via resiliently yielding device, such as permanent magnets. The brake disks are rotatably supported in the support or bearing device. Via an oscillatory motion generator, such as an electromagnet, mechanical or other device, the support or bearing means is set into mechanical oscillation that is essentially axial to the brake disks or in other words parallel to the axis of rotation defined by the rotation of the brake disks. The brake disks are carried along only slightly or not at all by the support or bearing device and the oscillatory motion generator.
