ABSTRACT:
Apparatus for the programmed change of position of one or more members, particularly of the nozzles of jet looms. The disadvantages of similar prior devices are mitigated by the arrangement of the device according to the invention in which a driving cam is provided with an auxiliary cam path for the cam following pin of a combined cam follower element, said pin being mounted axially displaceably on the carrier of the combined cam follower element and being urged toward the cam by a spring. One of the ends of said pin is controlled by the auxiliary cam path, while in the vicinity of the other end there is mounted a controlled arresting mechanism. The driving cam can be made in the form of a box or a globoidal cam. In the embodiment employing a globoidal cam, the pin of the combined cam follower element has its opposite ends of similar construction, while the combined cam follower element includes further auxiliary guiding pins which are arranged crosswise with respect to the pin of the cam follower.
