Definitions
- Mouthpiece for a thread-gripper with a pinstripe pinstripe for a mouthpiece and method for making a pinstripe
- the invention is directed to a mouthpiece for a thread gripper comprising a pin strip formed by a series of juxtaposed needles, the tips of the needles of the pin strip being positioned to project into the suction opening of the mouthpiece and to a pin strip for such a mouthpiece.
- a yarn gripper of the generic type is known from EP 0 398 415 B1.
- Thread grippers are also known in which a bent sheet metal section is provided in the mouth region, on which a pin strip is fastened in such a way that the tips of the needles protrude into the opening area.
- the pinstrip consists of a series of needles and two cover sheets, i. for the production of a total of a relatively large number of parts is required.
- sensors are provided to monitor the tear of the thread and interrupt the unwinding of the thread.
- To reassemble the broken ends of the thread it is necessary to seek and grasp the thread ends.
- the gripping of the thread on the side of the roll is usually accomplished by means of a suction mouthpiece.
- a pin strip is provided at the suction mouthpiece, to the exact positioning of which as well as to the tolerance of the position of the individual needles strict requirements be provided.
- mouthpieces which comprise double-folded retaining plates, wherein a prefabricated pin strip is fastened to the inside of the front end of the retaining plate.
- the pinstripe in turn comprises two cover plates. Both the production of the pin strip as such and the folding of the retaining plate is relatively expensive.
- the invention has the object, a mouthpiece of the type mentioned and a particular replaceable pin strip for this purpose so that a cost-effective production with low tolerance and accurate positioning in the tip area is possible.
- the needles are bent by about 60 °.
- the needles can be embossed and arranged on a cover plate, which in turn is connected to the mouthpiece.
- the free end of the cover plate overlaps the needles with the tips being released, whereby the front edge of the cover plate is advantageously ground in a wedge shape in the region of the tips of the needles.
- the needles can be adhesively bonded to the cover plate, wherein it is advantageously provided that hot glue strips are applied to the cover plate in the contact region of the pin strip.
- the invention is also directed to a pin strip for the mouthpiece of a thread gripper, which is characterized in that the needles, preferably at an angle of 60 °, are bent.
- the invention relates to a method for producing a pin strip, comprising a plurality of needles for the mouth piece of a thread gripper, which is characterized in that the needles are provided in the uncured state with a bend, hardened and then glued against a curved cover plate.
- a mouthpiece 1 of a thread gripper illustrated in the drawing comprises guide plates 2, 3 and a suction opening 4 formed therebetween, through which air is sucked in the direction of the arrow 5.
- a pin strip 6 is fixed, which consists of a series of juxtaposed embossed and bent by an angle ⁇ of 60 ° needles.
- Each individual needle 7 has a foot region 8 and a tip region 9 and a bend 10 between them.
- the needles 7 are glued to the needle strip cross gusset 11 by hot glue strips 12 and 13.
- the front edge 14 of the cover plate 11 is ground wedge-shaped and ends behind the tips 15 of the needles. 7
- the cover plate 11 is screwed to the guide plate 2 via continuous screws 16, 17.
