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 on a first point (P6) and on a second point (P7). The method further comprises a step of orienting the glue (G6) applied on the first point (P6) towards the second point (P7) and along said advancing direction (A), and orienting the glue (G7) applied on the second point (P7) towards the first point (P6) and along a direction opposite relative to said advancing direction (A).
Claims20
A method for applying glue on tubular cores for producing logs of paper material, the method comprising the steps of:
- supplying in sequence tubular cores along a predetermined advancing direction;
- applying a predetermined amount of glue on a first point on each of said tubular cores;
- spreading said glue applied on said first point along said predetermined advancing direction;
- applying a predetermined amount of glue on a second point on each of said tubular cores;
- and
- spreading said glue applied on said second point along a direction opposite said predetermined advancing direction such that said glue applied on said first point is oriented towards said second point and said glue applied on said second point is oriented towards said first point.
A device for distributing glue on tubular cardboard cores, the device comprising:
- a means for feeding in sequence tubular cores along a predetermined advancing direction;
- a gluing means for dispensing a predetermined amount of glue on a first point and on a second point on each of said tubular cores;
- a spreading means for spreading the glue provided on the first point towards the second point and for spreading the glue supplied on the second point towards the first point, said spreading means of the glue being arranged and acting along said predetermined advancing direction to orient the glue applied on the first point according to said predetermined advancing direction and to orient the glue applied on the second point along a direction opposite to the predetermined advancing direction.
A method for applying glue on cores for producing logs of paper material, the method comprising:
- supplying cores along a predetermined feed direction;
- depositing glue on a first area of each of said cores;
- rotating one of said cores in a first direction such that said glue deposited on said first area forms a first elongated glue area;
- depositing glue on a second area of said one of said cores;
- rotating said one of said cores in a second direction such that said glue deposited on said second area forms a second elongated glue area, said second direction being opposite said first direction.
