Abstract
A machine for unwinding and rewinding a covering tape (800) includes a first support shaft to coaxially receive a reel of covering tape, a second support shaft, parallel to and distanced from the first support shaft, which is adapted to coaxially receive a tubular support, a motor adapted to put the second support shaft in rotation around its own axis, a plurality of contrast rollers arranged around the second support shaft and oriented parallel thereto, and a movement apparatus adapted to move the contrast rollers towards and away from the axis of the second support shaft.

A machine for unwinding and rewinding a covering tape, comprising:
- a first support shaft adapted to receive coaxially a reel of covering tape,
- a second support shaft, parallel to and distanced from the first support shaft, which is adapted to coaxially receive a tubular support,
- a motor adapted to put the second support shaft in rotation around its own axis (A″),
- a plurality of contrast rollers arranged around the second support shaft and oriented parallel thereto, and
- a movement apparatus adapted to move the contrast rollers towards and away from the axis (A″) of the second support shaft,
- wherein said movement apparatus comprises:
- a first frame adapted to carry at least one of said contrast rollers,
- a second frame adapted to carry the remaining contrast rollers, and
- actuation members to move said first frame and said second frame in opposite directions along a same sliding direction (Q) orthogonal to the axis (A″) of the second support shaft.
A method for unwinding and rewinding a covering tape by a reeling machine wherein the reeling machine comprises:
- a first support shaft adapted to receive coaxially a reel of covering tape,
- a second support shaft, parallel to and distanced from the first support shaft, which is adapted to coaxially receive a tubular support,
- a motor adapted to put the second support shaft in rotation around its own axis (A″),
- a plurality of contrast rollers arranged around the second support shaft and oriented parallel thereto, and
- a movement apparatus adapted to move the contrast rollers towards and away from the axis (A″) of the second support shaft, and
- wherein the method comprises the steps of:
- fitting a reel of covering tape coaxially onto the first support shaft,
- fitting a tubular support coaxially onto the second support shaft,
- fitting one free end of the covering tape of the reel between the tubular support and at least one of the contrast rollers,
- bringing the contrast rollers closer to the axis (A″) of the second support shaft, so as to tighten said free end against the tubular support,
- putting the second support shaft in rotation, and
- as the covering tape winds onto the tubular support, progressively moving the contrast rollers away from the axis (A″) of the second support shaft, while keeping each one of the contrast rollers in contact with the covering tape wound on the tubular support.

- a second support shaft, parallel to and distanced from the first support shaft, which is adapted to coaxially receive a tubular support,
- a motor adapted to put the second support shaft in rotation around its own axis (A″),
- a plurality of contrast rollers arranged around the second support shaft and oriented parallel thereto, and
- a movement apparatus adapted to move the contrast rollers towards and away from the axis (A″) of the second support shaft and adapted to bring the contrast rollers closer to the axis (A″) of the second support shaft up to a neared configuration in which the contrast rollers are all contemporarily at the same distance from the axis (A″) of the second support shaft.
