Abstract
Tentering clamps for an endless tentering chain are formed so that two clamp bodies slideably mounted on at least one common guide bar can move toward each other and away from each other for adjusting the pitch. The guide bar or bars have entraining stop elements so positioned that an axial pulling force that moves the tentering chain, is transmitted through the guide bar or bars. The pitch is adjusted with the help of at least one, preferably two, toggle link mechanisms carrying a control roller engaging a guide rail. When the toggle links of the toggle link mechanism are straightened out in the travel direction of the tentering chain, the toggle link mechanism is substantially relieved of the axial tension force or load because the load passes through the guide bars (10) and the clamp bodies forming a pair. A plurality of such compound tentering clamp body pairs are linked by chain link plates and respective linking chain journal pins (23).
