ABSTRACT:
The invention refers to a rewinding machine and a method for producing logs of paper; the machine comprises means for feeding a continuous paper web (2) along a predetermined path, means for operating a series of discontinuous transverse cuts in order to subdivide the web (2) into portions of sheets of predetermined length to be separated by tear, means for feeding tubular cores (1) upon each of which a preset number of sheets is to be wound to form a log, a cores (1)-guiding channel (C) which extends between a cores (1)-feeding station (A) and a station at which a log (RO) is formed, the said channel (C) being delimited in part by a fixed guide (3) and in part by a roller (RA) which cooperates for the feeding of the paper (2); the machine comprises a device (4, 5; 32, 31) able to deliver predetermined amounts of glue within said channel (C), the said device including first and second means (4, 31; 5, 32) located and acting on corresponding preset points being located between the station (A) for feeding the cores (1) and the station for forming the logs (RO).
