As already mentioned, the clamping unit is 6 fixed using the sleeve 28 in the housing 1.

Im Regelfall wird die Klemmkraft entsprechen den Eigenschaften eines Schussfadens eingestellt. Hierzu wird die Klemmung der Hülse 28 durch Lösen der Schraube 42 aufgehoben und die Hülse mittels eines Werkzeugs (nicht dargestellt) gedreht. Die Drehbewegung wird die Klemmzunge bezüglich dem hakenförmigen Abschnitt 12 geschwenkt. Danach wird die Klemmung der Hülse 28 durch Anziegen der Schraube wiederhergestellt (Fig. 6). As a rule, the clamping force will correspond to that Properties of a weft set. To do this the clamping of the sleeve 28 by loosening the screw 42 picked up and the sleeve using a tool (not shown) rotated. The rotary movement becomes the Clamping tongue with respect to the hook-shaped section 12 pivoted. Then the clamping of the sleeve 28 is carried out Tightening the screw restored (Fig. 6).

Beim Eintragen eines Schussfadens wird durch ein in der Laufbahn des Greifers vorgesehenes Stellglied (nicht dargestellt) die Lasche 7 verlagert und dadurch die Klemmzunge 22 bezüglich dem hakenförmigen Abschnitt 12 geschwenkt und der Schussfaden im hakenförmigen Abschnitt aufgenommen. Die Rückstellung der Klemmzunge erfolgt aufgrund der Elastizität der Klemmeinheit 6.When a weft thread is inserted, it is inserted into the Actuator provided for the gripper (not shown) relocated the tab 7 and thereby the Clamping tongue 22 with respect to the hook-shaped section 12 pivoted and the weft thread in the hook-shaped section added.
