Abstract
Apparatus for adjusting the spacing of drive assemblies for transport of tubular film over a forming tube includes adjustment arms attached to each of the separate spaced drive assemblies which are attached to a rotatable adjustment plate. Rotation of the adjustment plate about its axis simultaneously moves the drive assemblies in equal and opposite directions with respect to the centerline of the tubular film product.
