A holding and supporting group of a winding spindle in a machine for winding plastic film onto spools includes a winding reel positioned between two uprights, wherein a first upright carries a rotating plate which cantilever-supports three spindles and a central shaft, wherein the central shaft is supported at the other end by the second upright, wherein, in correspondence with a free end of the central shaft, there is a star-shaped plate with three supporting arms for each free end of the three spindles through a respective toggle lever mechanism driven by an actuator carried on a lever articulated with respect to the star-shaped plate, and in turn caused to oscillate between an operative blocking position of the respective spindle and a rest position for releasing the respective spindle by an additional actuator.

A rewinding system includes a rewinding apparatus for winding a manufactured thin-film tape on a re-winding roll; a loading apparatus for loading the re-winding roll on which the thin-film tape is rewound; and a cutting apparatus for cutting the thin-film tape. The rewinding apparatus includes first and second mounting members in which re-winding rolls are inserted; and a connecting member connected to an end of each of the first and second mounting members to move the first and second mounting members. The first mounting member rotates around a shaft thereof, the second mounting member rotates around a shaft thereof, and the connecting member rotates the first and second mounting members to change positions of the first and second mounting members, and moves at least one of the first and second mounting members to the place where the loading apparatus is arranged.

The rolled material dispenser of the present invention enables the user to securely grip the rolled material dispenser and safely cut rolled material installed within. The rolled material dispenser provides beveled corners allowing for better gripping and usage for users with decreased hand strength and dexterity. The user inserts the rolled material of their choice into the dispenser. The user opens the lid of the rolled material dispenser, pulls a desired length of material from the roll installed inside the dispenser device, and then closes the lid. Closing the lid secures the rolled material and positions the cutting device to sever the desired length of material. The cutting device travels along the track of the lid. The user slides the cutting device across the rolled material positioned underneath the lid to cut a portion of material from the roll installed within the dispenser.
