ABSTRACT:
A tentering frame is equipped with a tentering chain for the simultaneous treatment of a film web in two directions or in a so-called biaxial manner. The film web is carried by endless tentering chains which hold the film web edges by grippers carried by tentering clamps secured to the tentering chain. The chains have tiltable chain link plates and chain links, whereby the on-center spacing between neighboring clamps is continuously adjustable or variable for changing the chain pitch. In order to reduce the normal pitch when the chain is stretched out as much as possible, and in order to achieve a more efficient pitch adjustment in a larger adjustment range, each tentering clamp is carried by a single shaft which simultaneously functions as one of the two chain pins or chain axles that link two neighboring chain links to each other. One of the chain link plates, either the inner or the outer chain link plate, is formed as an angled bellcrank type of lever carrying control rollers which cooperate with respective control rails for the continuous variation of the chain pitch.
