• the testing member is capable of providing an additional function for detaching the paper strip from the service roll during the finishing phase. Due to its length, the test member comes to bear on the paper strip of the roll to be finished. During the rotation of the drum, for the last strip of paper to be dispensed, this is glued to the support sleeve of the spool, according to a known technique to allow winding. Due to the lightness of the sleeve, the drum, by turning, drives the paper, and therefore the sleeve associated with it.
