ABSTRACT:
A transmission arrangement includes a plurality of transmission linkages, of which at least one performs an oscillating movement which is repeated during each period. A control cam is formed on a first transmission linkage and a feeler roller is rotatably mounted on a second transmission linkage. The control cam and a contact surface of the feeler roller are in operative rolling contact during at least part of a period repeating in the respective periods. The second transmission linkage has a degree of freedom with respect to a bearing support which allows shifting due to deflections of the feeler roller mounted on the second transmission linkage as a result of a relative movement between the control cam and the feeler roller. A point on the contact surface of the feeler roller which coincides with a first contact point in a first operational setting of the second transmission linkage coincides at least approximately with a second contact point in a second operational setting of the second transmission linkage.
