Abstract:
1. A device for gluing the final edge of a log of a band-shaped material, comprising: a rolling plane for supporting and rolling at least a log of a band-shaped material, said rolling plane having at least a through opening for the application of a glue on an outer surface of said log; and at least an application blade operatively associated to said rolling plane for the application of said glue on the outer surface of said log, said application blade having at least an application edge able to sustain at least a predefined layer of glue and being moveable, along a handling direction (DM) transversal to said rolling plane, between a first position, in which said application edge of said application blade is spaced from said through opening, and a second position, in which said application edge of said application blade is disposed close to said through opening of said rolling plane, so that the rolling of said log determines the contact between the outer surface of the latter and the application edge of said application blade, wherein it comprises at least a pressure container for housing said glue to be delivered to said application blade, said housing container being separated from said application blade and disposed according to a position substantially flanked with the same, said housing container having at least a slot facing and near to said application edge of said application blade when the latter is in its first position, said slot defining an expulsion direction of said glue, transversal to the handling direction (DM) of said application blade so that said glue, expelled through said slot, settles on said application edge according to a predefined quantity.
