ABSTRACT:
A link device for stretching a sheet material consists of pantograph-like link member units having a sub-link held substantially at a right angle to the running direction and rollers fitted to said sub-link. Due to the low running resistance of the rollers and the pantograph-like structure composed of long and short links, an endless guide-rail can be introduced in the stretching apparatus for a sheet material and the running of the chain can be stabilized, thereby resulting in a high-speed stable stretching operation. Reduction of the running resistance makes it easy to adjust the stretching ratios according to the desired stretching conditions.
