rod 22 that is on the one hand to the arm 20 and on the other hand to the angle lever 23 are mutually orthogonal fig4 shows another embodiment for the control lever 14 arrangement again this arrangement is underneath the fabric path 18 and is displaceable on a block 12 in a groove 3 39 of the crossbeam 3 contrary to the case for fig2 the control lever 14 in this instance is supported not on the control shaft 11 but rather with a separate axis of rotation in a bearing 26 of the block 12 parallel to the axis of the control shaft 11 in this instance the control lever 14 includes two further arms 20 and 21 each bearing a sensor roll 27 to sense the cam motion the constraned control cam in this instance is assumed to be a double eccentric 28 solidly connected to the control shaft 11 each of the rolls 27 rests against its associated cam disk 28 this constrained control allows dispensing with return springs for the control lever 14 and hence with their possible drawbacks the design of the control lever 14 and its operation in cooperation with the reed 9 and the gripper system 16 is similar to the example of fig2 in this instance also the.
