Definitions
- the invention relates to a Holer gripper according to the Preamble of claim 1.
- the holer gripper contains one in essential U-shaped body with a hook one end, a clamping tongue with an end section, the protrudes from the hook mouth and one with the inside of the mouth wedge-shaped clamping gap and a deflecting edge that on the side of the holer gripper facing the specialist tip is provided.
- This edge is either by means of a leaf spring that is screwed to the base body or by means of a side wall of the base body formed, the leaf spring or the side wall in the Protruding hook mouth.
- the width of the leaf spring or the height the side wall are designed such that the Deflecting edge and the top of the hook at the same level lie.
- This disadvantage mainly occurs when short before the end of the weft insertion, while the holer gripper in Term is to leave the shed (e.g. in Spreader area), the shed is already closing.
- the invention is based on the object To create holer grabs, where the specified disadvantage does not occur.
- FIGS. 1 and 2 the Fig. 1 is a schematic representation of the preferred Embodiment is and the Fig. 2 the Holgerreifer in shows the final phase of the entry process.
- the Holer gripper contains one Base body 1 with a hook 2, a clamping tongue 3, one Mechanism 4 for actuating the clamping tongue and a Rejection organ 5.
- the basic body is essentially U-shaped.
- the side wall 11 on the reed side runs out in the hook tip 13 and the tissue side Side wall 12 ends in the mouth opening, so that a The opening for inserting the weft remains.
- the Clamping tongue 3 protrudes into the mouth opening and forms with the free leg 14 a wedge-shaped clamping gap 15 for a weft thread 16.
- the clamping tongue 3 is on the other hand connected to the mechanism 4 to the clamping gap Open a weft thread. Closing the Clamping gap occurs automatically through the mechanism.
- the deflector 5 is within the base body 1 and arranged alongside the clamping tongue.
- the rejection organ is with suitable means on the inside of the attached side wall 12.
- the Repeller 5 is strip-shaped and so dimensioned that one end in the area of mechanism 4 with widened base body and the other end in the hook mouth protrudes and that a section on the Protrudes the top of the base body 1, the one Deflection edge 18 forms.
- the end sections 19, 20 of the Deflector 5 are chamfered so that the deflector edge 18 runs obliquely towards the base body.
- the sagging warp thread 21 is by means of the deflecting edge 18 is kept at a level which prevented from being caught by the hook. Through the Deflection edge 18 running obliquely against the base body the warp thread is gradually raised to the level and prevents warp thread jams.
- the 3 shows a second deflecting edge 25 on, which is formed by a web 26.
- the bridge 26 runs obliquely on the top of the clamping tongue 3 and is essentially parallel to the clamping area Clamping tongue arranged or fastened.
- the holster gripper has a U-shaped base body 1 a hook 2, a clamping tongue 3, a mechanism 4 for Actuation of the clamping tongue and a deflector 5.
- the deflector is along the inside of the base body 1 the clamping tongue 3 arranged so that the upper edge of the Deflector 5 protrudes over the top of the base body, to take up loose warp threads 21 by the hook 2 to prevent.
