Abstract
A gluing device including a guide roller to guide the tail of the log; on the guide roller, retaining elements to engage and retain the tail on the guide roller; a gluing member, to apply a glue to the tail retained on the guide roller. There are also provided embossing members, arranged and controlled to emboss a portion of the tail of the log. The gluing member applies the glue to embossing protrusions formed by the embossing members.
Claims5
A method for gluing a tail of a log of web material, comprising
- identifying the tail of the log to be glued;
- unwinding the tail;
- embossing the tail with embossing members to form on the tail embossing protrusions by the embossing members;
- after formation of the embossing protrusions by said embossing members, applying a glue to the embossing protrusions;
- rewinding the tail and gluing the tail to an outer surface of the log;
- and
- further comprising engaging said tail with a guide roller, around which a gluing member and a pressure member are arranged;
- the pressure member cooperating with embossing protuberances on a cylindrical surface of the guide roller to emboss the tail of the log, said pressure member and said embossing protuberances forming said embossing members;
- and said gluing member applying a glue to the embossing protrusions generated on the tail of the log by said pressure member.
A method for gluing a tail of a log of web material in a gluing device, comprising
- feeding the log in the gluing device;
- unwinding the tail from the log;
- in the gluing device, embossing the tail unwound from the log with embossing members to form on the tail embossing protrusions by the embossing members;
- after formation of the embossing protrusions by said embossing members, applying a glue to the embossing protrusions;
- after application of said glue, rewinding the tail and gluing the tail to an outer surface of the log.
A method for gluing a tail of a log of web material in a gluing device, comprising
- introducing the log in a gluing station of said gluing device;
- in said gluing station, embossing the tail with embossing members to form on the tail embossing protrusions by the embossing members and, after formation of the embossing protrusions by said embossing members, applying a glue to the embossing protrusions;
- after application of said glue, rewinding the tail and gluing the tail to an outer surface of the log.
