<p>The present invention concerns a device and a method to control and adjust, in terry looms, the movements of the take-up roller and of the warp yarn guiding roller which cause the forming of terry loops, said device being of the type comprising a drive shaft (1) for transmission of a main rotary movement and an outlet lever (2) caused to rotate with an oscillating movement, between these two elements (1, 2) there being provided first mechanical members to determine the motion law and second mechanical members, in the form of a kinematic chain, to adjust the amplitude of said oscillating movement; said device also comprises actuating means apt to change the geometrical position of a movable hinge (10) of said kinematic chain, so that a specific transmission ratio and thus a given loop height may correspond to each of the geometrical positions taken up by said movable hinge (10).</p> |
