Definitions
- the invention relates to a slave rapier for a rapier weaving machine with a gripper housing at the front end a clamping hook is provided which has a clamping surface, which is assigned a counter clamping surface of a clamping head, which is held on a tongue that is at a distance from the clamping head articulated on a pivoted lever and with a Spring is loaded that the clamping head in the clamping position suppressed.
- This object is achieved in that the clamping head between two guides of the clamping hook at an angle to the longitudinal direction of the gripper and positively guided obliquely to the direction of the clamping surface is.
- the one of the clamping hook Exerts force on the tongue transversely to the longitudinal direction of the gripper, since the clamping head only the one predetermined by the two guides Can perform movement.
- the guides are housed in the clamp hook are, a very slim shape can be realized. This has the advantage that, according to the encoder gripper, in which of the taker grabs when picking up a weft penetrates, can also be kept relatively slim. This then leads to the advantage that only one during weaving relatively small shed is required.
- the guides in one or more parts are provided, which is attached in a recess of the clamping hook is.
- This can be a suitable one for the tours Select material without the entire clamping hook this material must exist.
- the slave gripper shown in the drawings has a Gripper housing 10 made of metal, which is not shown in detail Way attached to the front end of a gripper belt becomes.
- a Clamping hook 11 attached, which has a clamping surface 12.
- This clamping surface 12 is a counter clamping surface 13 Clamping head 14 assigned.
- the clamping head 14 is on the front end of a tongue 15, the rear end of one Actuating lever 16 is articulated about an axis 17th is pivotally mounted in the gripper housing 10.
- the operating lever 16 is loaded with a compression spring, which is in the longitudinal direction of the gripper is aligned and the lever Tongue 15 loads the clamping head 14 with its counter clamping surface 13 against the clamping surface 12 of the clamping hook 11 suppressed. If the lever 16 is pushed in, as shown in 4 and 5 is shown, the clamp is opened.
- the clamping head 14 has two substantially parallel to each other running guide surfaces 19, 20 which are inclined to Gripper longitudinal direction and obliquely to the clamping surface 12 of the Clamping hook 11 are directed.
- the guide 21 has a groove-like Profiling 23, in which the corresponding profiled Guide surface 19 of the clamping head guided in the transverse direction is.
- the 10 and 11 are the guide surfaces 19, 20 of the clamping head 14 and the guides 26, 27 of the clamping hook 11 profiled such that they are on circular paths to a parallel to the axis 17 of the operating lever Axis. With the help of such training of the guides and guide surfaces it is possible to adjust the elastic deformation to limit the tongue 15. At least one of the guides 26 or 27 may also be profiled transversely, such as this 6 and 7 is shown.
- the guides 26, 27 are Part of a one-part or two-part insert, which is mounted in a recess of the clamping hook 11.
- the exemplary embodiments shown serve only for explanation the invention. Modifications are easily possible, especially with regard to the design of the tours for the clamping head 14. For example, it is also possible to use the Clamping head 14 with a cylindrical neck or with an or several cylindrical bolts in corresponding hollow cylindrical Guides.
