  • Multistage tenter
    Patent number: 5129163
    Abstract: In a multistage tenter with the right and left clip chains for conveying a belt-shaped film in a drying unit, a tensing mechanism operates to slide the supports of a pair of right and left sprockets engaged with the clip chains to tension the latter simultaneously, so that the shorter of the two clip chains is automatically tensioned more than the other, whereby the pitch error of the clip chains is absorbed, and the film is accordingly prevented from being wrinkled while being conveyed.
