A control leverage mechanism of a travelling-head tuck-in device for a weaving loom comprises the following functional groups of levers:
- a first articulated quadrilateral (Q1), the end hinges of which (1, A) are fixed to the loom, which takes the alternate movement from the loom sley (S);
- a connecting rod-crank mechanism (G1) which receives on the crank (L2) the movement from the first articulated quadrilateral Q1 and transmits it through a connecting rod (LR) to the travelling head (LC) of the tuck-in device on which the moving end of said connecting rod is hinged (in B); and
- an articulated parallelogram (P1) which connects the body (CC) of the tuck-in device to the travelling head (LC) of the same, for guiding said travelling head (LC) of the tuck-in device between a forward home position and a backward operating position, along an arc wide enough to approximate a rectilinear movement. |
