Abstract
Method for applying glue on tubular cores for the production of logs of paper material comprising the step of supplying in sequence more tubular cores (1) along a predetermined advancing direction (A) and the step of applying on each of said cores (1) a predetermined amount of glue, and the glue is applied on the tubular cores (1) from the above. While advancing along said direction (A) and without interrupting their run, the tubular cores (1) intercept for a predetermined time the glue (EG) released by a predetermined number of nozzles (114); and during said time interval the glue (EG) is both on the nozzles (114) and the tubular cores (1) given the absence of any element interposed between the nozzles and the tubular cores.

A method for applying glue on tubular cores for producing logs of paper material, the method comprising:
- supplying in sequence tubular cores along a predetermined advancing direction;
- and
- applying a predetermined amount of glue on each of the tubular cores, the glue being applied on the tubular cores from a predetermined number of nozzles provided above the tubular cores, the tubular cores intercepting the glue released by the predetermined number of nozzles for a predetermined time interval while advancing the tubular cores along the predetermined advancing direction and without interrupting a run of the tubular cores, the glue being on the predetermined number of nozzles and the tubular cores during the predetermined time interval without any element interposed between the predetermined number of nozzles and the tubular cores.
