Definitions

the present invention provides a drawing gripper which, by virtue of its clever configuration - deriving besides from careful considerations as to the mechanics of the yarn exchange at the shed centre - provides an extremely satisfactory solution to the examined problem.
the drawing gripper comprises a fixed member 1 with a hook end 2 and a mobile element 3 mounted oscillating about 4 on the memeber 1 and designed to cooperate in known manner with the inner part of the hook of the end 2 in order to retain the weft yarn.
This arrangement of the hook 5 is combined, in the gripper according to the invention, with a special structure for protecting the warp yarns, constituted by a simple vertical fin 6 projecting from the member 1 carrying the hook 5, and disposed to the side of this latter.
the downwardly open hook arrangement results from the fact that most of the inconveniences occuring at the moment of weft yarn exchange between the carrying gripper and the drawing gripper, are determined by the rotation movements of the carrying gripper about its longitudinal axis such as to lift the side thereof close to the reed, these movements causing a lifting of that portion of weft yarn which has to be gripped by the drawing gripper. It is precisely under such conditions that the upwardly open hooks of conventional grippers, which lie below the weft yarn in order to grip it, are unable to grip said yarn which, if being lifted, tends to escape from the hook. Whereas, with the downwardly open hook arrangement according to the present invention, the grip is always reliable and immediate, because the weft yarn is gripped when the hook is above it, whereby any lifting of the yarn will not determine its escape.
the vertical fin 6 for protecting the warp yarns forms a very efficient obstacle against any penetration of warp yarns towards the hook 5 and simultaneously reduces the overall vertical size of the gripper.
