Abstract:
Apparatus for applying glue to a tubular core in a re-reeling device for winding logs of material in strips, said apparatus comprising a conveyor (12, 13) which sequentially feeds cores (11) which are distanced from one another, in succession, at a controlled conveyor speed through a means (21, 15, 16) for applying glue (19) to each of said cores (11), wherein said means for applying glue comprises a first and a second rotating roller that are rotated at substantially the same speed of rotation said rotation speed being synchronized with said controlled conveyor speed, said first roller (14), being at least partly immersed in a tank (15) of glue (19), with at least one portion of a generatrix of said first roller (14) coming into contact with the core (11) which is fed by said conveyor (12, 13), at said controlled conveyor speed, and said second roller (16), being positioned opposite said first roller (14), with said first and second rollers interacting with said core (11) to cause said cores (11) to be fed without rotation through said means to apply glue in synchronization with the feed of said conveyor (12, 13).
