Device for metered distribution of glue on an end edge of a log, a log or a core for log

A device for the metered distribution of glue on an end edge of a log, a log or a core for a log comprising a feed (26) for logs (19) or a core for a log (25) towards a wire (12) wound in a closed circuit on at least two end pulleys (13), at least one of which is continuously rotated by a gearmotor (14), said device further comprising a means for the delivery of glue under pressure (30, 40) located above said wire (12) in a position upstream of a wire branch designed to release a strip (21) of glue on an end edge (18) of a log (19), or a core (25) for a log, in addition to an element (15) for recovery of the glue (20) arranged below a return branch of the wire said means for delivery of glue under pressure comprising a delivery reservoir (30) for the glue (20) positioned above said wire (12) and provided on a lower side with a recess (34) with a width at least equal to the diameter of the wire (12), said recess having walls (36) that are provided with at least one hole (35) for delivery of the glue (20), said delivery reservoir (30) being designed to release a quantity of glue (20) onto the wire (12) and is positioned above one of said at least one of two end pulleys (13) unstream of the upper branch of the wire (12), the bottom of said recess (34) having substantially the same profile as the portion of wire (12) to which the delivery reservoir (30) is applied and said at least one hole (35) is provided on the bottom of the recess (34).
