ABSTRACT:
A device for adjusting the position of two protective film rolls in laminators having two roll shafts individually having a hexagonal cross-section. The right end of each roll shaft is movably received in a cap. A bolt, having a circular head, a woodruff key part and an externally-threaded part, is fitted into a semicircular hole of the cap at the woodruff key part. The bolt also passes through a hole of a right-hand bracket of the laminator prior to engaging with a tension adjusting handle at the externally-threaded part. Both a compression coil spring and a first bushing are commonly fitted over the bolt at a position between the bracket and the handle. A bolt part axially extends from the left end of each roll shaft, while two shaft adjusting handles movably engage with the bolt part. Doubled bushings are fitted over the bolt part at a position between the two shaft adjusting handles.
