ABSTRACT:
An adjusting device of a thermo shrinkable film machine includes first and second blocks movably mounted on two rails between two sideswalls on the base of the machine. Each of the two blocks has a wheel for contacting the film on a shaft. Two rotatable rods have two threaded sections of different directions of threads which rotatably extend through the two blocks respectively. The two respective ends of the two rotatable rods are connected to a rotating piece which is rotatably received in a case located between the first and second blocks. A driving wheel drives one of the rotatable rods so as to move the two blocks in opposite directions and to adjust the distance between the two wheels contacting the film of different thickness.
