Abstract

The gripper comprises a housing (1), a clamping part (5) what a hook-like clamping section (12) receiving a weft yarn and a clamping unit (6) with a clamping tongue (22), a torsion bar (23) and a cover plate (7). The clamping tongue (22) is pivotable, cooperates with the clamping section (12) and is influenced by the torsion bar (23) in order to clamp the weft yarn. The clamping force is applied by the torsion bar (23) and the effect of the clamping is neutralized by the cover plate (7). One advantage of the gripper is that it consists of a minimum number of parts. Another advantage is that it is extremely compact.

V. Invention Description (1 ·) Patent Case No. 89108336 Amendment to the Invention Description Whether the original substantive content is changed after the amendment of this case. According to the general idea of item 1 of the scope of patent application, the present invention is about The gripper and device, and a conventional gripper printed by a consumer cooperative of the Intellectual Property Bureau of the Ministry of Textile Economy with such a device, are composed of various different wire clamps. Basically, the wire clamp is composed of a fixed clamping member, a movable clamping member, a spring element and an actuating mechanism, and is distinguished according to its clamping method and its clamping action. In a certain type of gripper, a fixed gripper constitutes its shell, and one of the grippers is used to receive the weft yarn, and a movable husband gripper constitutes and grips a tongue. The sheet can be moved along the longitudinal direction of the shell under the action of the coil spring so as to hold the weft yarn. The actuating mechanism is coupled with the clamping tongue in order to guide and move the clamping tongue having a spring action with the casing. In another type of clamping jaw, the fixed clamping member constitutes its shell, and it has a hook-shaped clamping member for receiving the weft yarn, and the movable clamping member constitutes its clamping lever. In order to clamp the weft yarn, The clamping lever can swing back and forth under the action of a coil spring, and its swing axis is perpendicular to the longitudinal direction of the casing. The application of this coil spring has proven to have disadvantages, as the methods used to hold and / or guide the same need to be considered first. U. It is known from DE-B-1 087 87 088 a jaw of the type described at the outset ' The invention is described later. A torsion spring is designed as a helical spring, and is arranged on a rotatable cymbal, which records-clamping tongues. This twisted paper size applies the Chinese National Standard (CNS) A to the standard. (Please read the precautions on the back before filling this page) ιδτ *

The advantage of this design is that it enlarges and increases the surface and surface area to increase the ditch, so that it can lengthen the rotation and increase the holding power and increase the miscellaneous force. The interlocking plate 7 of the movable clamping member 5 is connected to the shaft member 21 by a locking mechanism. The design here uses a bolt 37 method. As shown in FIG. 6, the lock block M with the position 42 is tilted into the casing 4 to fix the sleeve 28. As mentioned before, the holding unit 6 is fixed in the housing 1 using a sleeve 28. ^ Generally speaking, the adjustment of the clamping force should be consistent with the characteristics of the weft. In this regard, the fastening function of the sleeve 28 is loosened by loosening the bolt 42, and the sleeve is rotated by a tool (not shown). The clamping tongue is thus rotated relative to the hook shape. The file 12 is rotated. After that, the sleeve 28 can be fastened and locked again by tightening the screw (Figure 6). During the feeding of the weft yarn, the interrogation plate 7 is moved by a control mechanism (not shown in FIG. 7F) arranged on the gripper path, and the gripping tongue piece 22 is thereby rotated relative to the hook member 12, and the weft yarn is taken in The hook-shaped part.
