Abstract
A device (1) applies adhesive to cores which are used to produce a log includes a moving means (3) configured to cause at least one core (5) to advance along a feed direction (A) and a dispensing means (7) configured for dispensing an amount of adhesive (9) on the core (5). The dispensing means (7) are moveable along an application direction (B) substantially orthogonal to the feed direction (A) and are configured to selectively dispense an amount of adhesive (9) along portions (11) of the core (5) during movement along the application direction (B).

A device (1) for applying an adhesive to cores comprising:
- a moving means (3) configured to cause at least one core (5) to advance along a feed direction (A), the feed direction being a linear direction along a radial axis of the at least one core (5);
- at least one dispensing means (7) configured for dispensing an amount of the adhesive (9) on said core (5);
- and
- an adjustment means (13) for adjusting of a position of said dispensing means (7) along said feed direction (A), the position of said dispensing means (7) along said feed direction (A) being adjustable according to the diameter of said core (5), wherein said
- dispensing means (7) is movable along one first linear guide (21) in an application direction (B), wherein said application direction (B) is substantially orthogonal to said feed direction (A) and parallel to an axial length of the at least one core, said one first linear guide (21) extends in the application direction (B), and said dispensing means (7) is configured to selectively dispense said amount of the adhesive (9) along at least one portion (11) of said core (5) during movement along said one first linear guide (21) in said application (B);
- and
- said adjustment means (13) includes a second actuator (23) adapted to move said at least one dispensing means (7) along a second linear guide (25) extending along said feed direction (A);
- wherein a single first actuator (19) is adapted for moving all of a plurality of dispensing means (7) in synchrony along the one first linear guide (21) in the application direction (B).
A method for applying an adhesive to cores comprising the steps of:
- causing at least one core (5) to advance along a feed direction (A), the feed direction being a linear direction along a radial axis of the at least one core:
- delivering an amount of the adhesive (9) to said core (5) by means of at least one adhesive dispensing means (7);
- moving said at least one dispensing means (7) along an application direction (B), said application direction (B) is substantially orthogonal to said feed direction (A) and parallel to an axial length of the at least one core;
- adjusting, according to a diameter of said core (5), a position of said dispensing means (7) along said feed direction (A) with an adjustment means (13);
- selectively delivering said amount of the adhesive (9) along at least one portion (11) of said core (5) during movement of said dispensing means (7) along said application direction (B), wherein the adjustment means includes at least one second actuator (23) adapted to move said at least one dispensing means (7) along an at least one second linear guide (25) in said feed direction (A), said second linear guide (25) extending along said feed direction (A), such that said position of said dispensing means (7) is adjustable along said feed direction (A);
- and
- moving with a single first actuator (19) allo f a plurality of dispensing means (7) in synchrony along one first linear guide (21) in the application direction (B), wherein said first linear guide (21) extends in the application direction (B).
