ABSTRACT:
A biaxial stretching machine has a return line for each row of grippers, the return line including a storage region defined by a section of storage track and a screw for feeding grippers to the storage track. The screw is of diminishing pitch and is axially compressible to vary the effective capacity of the storage region. In one form the return screw can be compressed by a spindle-nut-arrangement.
