Abstract: A log or single small roll of paper with improved clamping of the final or end strip, in which a final or end strip (13) is bound to a side portion of a body of a log or single roll (11) of paper for domestic use, toilet paper and similar products through glue or similar adhesive, in which the final or end strip (13) is bound to the body of a log or single small roll (11) through localised bonding elements or zones (14) of various size and measurement. The localised bonding elements or zones (14) comprise at least one section, drawing, logo, mark or the like (15, 115) and are realised through the deposition of glue or similar adhesive or else through the deformation of said paper adapted to receive glue or similar adhesive.

Abstract: A machine dedicated to the recovery of paper, generally of pure cellulose and therefore of optimal quality which may be integrally reused in the same productive cycle, a different recovery from that of the cardboard composing the core of the source roll which does not permit the reuse of the paper around it. Indeed, here the trimming rolls are recovered coming from the cutting of rolls for domestic or sanitary use. The recovery occurs after having arranged the rolls with the axis vertical, operating the insertion in the rolls of a guide bar which, with appropriate actuators, cuts them along the generatrix of the roll, maintaining the tube on the bar and allowing the paper to fall and then suctioning it and sending it to recovery, separately from the tube which remains gripped on the bar.
