Definitions
- the invention relates to a thread brake for the supplier a circular knitting machine according to the preamble of claim 1.
- a known thread brake of the generic type (EP-A-0321377) is on a location of the supplier housing stored after the Knot catcher, usually on a stationary Axis. This has, for example, the shape of a deflection bolt on which the thread in its Run from a supply point over a driven thread winding body to a processing point of the machine to be led.
- the thread brake usually consists of two on the above Axle-mounted brake actuators, which are adjustable Spring pressure are pressed against each other and between which the thread runs through, so slowed down, that he always the desired tension for the thread run having.
- the invention is therefore based on the object, the thread brake to design the generic type without significant construction and cost such that the thread abrasion is reduced and brake plate contamination be avoided, so that the overall function of the thread brake is improved and thus the operating times of the Knitting machine or the like are extended.
- the drive for the thread brake be that it is from the common drive for the thread winding body is independent and can still be realized with little material and construction effort.
- the invention is based on the essential idea that Train the driven axis of the thread brake such that the speed of the thread brake is constantly lower than that of the bobbin.
- the invention uses in incredibly simple way the already existing Drive for the thread winding body.
- the axis of the thread brake via a deflection or Reduction gear with the drive for the thread winding body coupled.
- the reversing gear adjust or dimension such that the Speed of the thread brake by a multiple, i.e. for example in a ratio of 1:20, compared to the speed of the Thread winding body is reduced.
- the configuration according to the invention can be mentioned without any noteworthy Realize construction and costs, because it is only necessary that previously stationary or non-rotatable
- the axis of the thread brake is now driven Axis, in such a way that, as mentioned, the thread brake has a lower speed than the thread winding body having.
- the arrangement so that the drive for the thread brake each tapped from the drive of the associated thread winding body is. This is done using a Gear train.
- the drive shaft of the thread winding body with a parallel gear axis a deflection or reduction gear is coupled, which in turn drives the axis of the thread brake.
- Thread feeder leading to the feed shown in the direction of the arrow a thread 1 from a supply point to a processing point a knitting machine or the like Supplier housing 2 on one at the head of the relevant retaining ring 3 provided machine (see Fig. 3) is definable.
- Different are on the feeder housing 2 Guides for the running of the thread 1 attached, namely a thread guide plate 4 with a thread eyelet 5, a knot catcher 6, a thread brake 7, one used for thread storage Button 8 in the form of an articulated on the supplier housing 2 Linkage and finally another thread eyelet 9, the underside in the manner shown on the supplier housing 2, protruding downward from this, is fastened and the thread 1 leads to a thread winding body 10.
- the thread winding body 10, which is a concave retracted inward Has peripheral surface is rotatable on the underside of the supplier housing 2 stored. To this end it is non-rotatable with one end of a drive shaft 11 connected, the rotatable in the supplier housing 2, this assertive, stored and on the top of it Supplier housing 2 protruding part two rotatably connected drive wheels 12, 13 carries. These are in turn, only indicated by means of one in FIG. 2 illustrated drive belt 14 driven.
- the thread 1 runs on its way between the two Thread eyelets 5, 9, the thread brake 7, after the knot catcher 6 is arranged and has two brake actuators 15, 16 between which the thread 1 runs through and that shown in the In each case, an inwardly curved peripheral surface or have thread contact surface.
- the two Brake adjuster 15, 16 of the thread brake 7 are freely rotatable on an axis 17 which is transverse to the running direction of the thread 1 protrudes from the supplier housing 2.
- On axis 17 a helical compression spring 18 is arranged, which is between an adjustable knurled nut 19 and the right one Brake actuator 16 supports as shown in FIG. 1. Because of this is right brake actuator 16 according to FIG. 1 by means of an adjustable Spring pressure against the left, axially fixed Brake actuator 15 pressed.
- the axis 17 of the thread brake 7 is a driven axis trained and is therefore via a separate drive driven, in such a way that the thread brake 7 or whose axis 17 has a lower speed than the thread winding body 10 driving drive shaft 11.
- the brake actuator 15, 16 rotatably with the to connect driven axis 17.
- the head 3 a knitting machine or the like in the already mentioned Way, the feeder housing 2 of the thread feeder, in regular Distance from each other, fixed.
- the drive belt 14 which over all drive wheels 13 the thread winding body 10 is guided and drives them together, through a single common Drive wheel 23 driven.
