Apparatus for glueing the tail of a web to a log formed of the web material

An apparatus for glueing the outer end of a web material forming a roll or log including:

• conveyor means (23) which lifts the roll or log vertically from a lower unwind position to an upper glue applying position,
• roller means for rotating the roll or log as it travels vertically on the conveyor means whereby to unwind the outer end of the material wound up to form a log,
• transport means on which the roll or log travels from the conveyor with the outer end of the material following behind the roll or log,
• means for applying glue on a portion of the web material still wound on the log in advance of the trailing outer end,
• means for rewinding the outer end so that said glue serves to adhere the said outer end of the log,
• means for transferring said log,
• said means for applying the glue comprising a dispenser device (55-63) having means (61) which form at least an upwardly oriented slit (63) from which the glue is dispensed by overflowing,
• said log (R) conveyor means (23, 41) arranged to discharge the log, with the outer end (L) unwound therefrom, thereby causing the log to roll over said slit (63),
• said slit (63) extending in a direction substantially parallel to the axis of the log (R) for at least a portion of the length of the log.

An apparatus for gluing a tail end of a web of material forming a log including:

• (a) a log loading wheel;
• (b) a pair of rollers for unwinding the tail end of said web of material;
• (c) a vacuum source for attracting said tail end of said web of material as said tail end is unwound from said log;
• (d) surface upon which said log rolls, said surface having a slot through which glue is applied to said log as said log rolls over said slot;
• and
• (e) a glue reservoir having a dispensing area adjoining said surface upon which said log rolls, said dispensing area being constructed and arranged so that said glue is applied to said log when said log rolls over said slot.
