Method for tail sealing a flat film web material wound on a ro Hogla present invention to a for a flat film b in particular wound on a roll called are various methods or the tail of rolls of toilet towel of these methods re based on the principle that a is placed between the free of the and the of the web extending said free these methods have serious inter they cannot be utilised when 2 ply rolls are to be in case the seals only th inner but does not come in contact with the outer it is very difficult tu utilise methods for automatic it is very difficult to distribute the glueing agen equally said free edge thus the sealed roll does not look nicely and a larger amount of glueing agent than theoretically required has to be and it is quite difficult to unseal the tail sealed by said known methods and in case of a toilet a number of sheets is lost as they are tome by said unsealing is also known a method for the tail of web wherein stripes of agent are externally applied all around this requires a of agent is also rather complicated as the agent has to he distributed all around the It has thus been desirable to find a method for the tail sealing of said material which the above drawbacks to a extent and not complicated and not too It surprisingly been found that the glueing agent is applied periodically to the outer part of free and the layer of the web extending below a proper tail sealing is The invention thus consists in a for tail sealing a flat film web material wound on a wherein agent is applied by an applicator outer end of the edge of said web and to the layer of the web below and constituting substantially a continuation of edge in such a manner tha the glueing agent crosses periodically said edge and thus o the glueing agent is She pattern formed by the glueing agent is not a critical feature of the present as long it enables a good tail sealing of a periodic crossing of the web may or be a sinusoid or have any other suitable distance of the various stripes of glueing agent from each other and the length whether stripes extend or are so adjusted tha proper sealing is achieved and the amount of agent to bo utilised is maintained is that the web edge is moved in a manner along the or vice versa the applicator the that the gluein agent is properly the edge has to pass the applicator in In instances the apparatus by method is performed will be so built that either log or applicator to be tilted when the glueing agent is Applying the glueing agent in connection the any suitable The glueing agent may any suitable commercially glueing or hot melting which has can bo used in an applicator and enables the proper tail of the As suitable glueing agents may be manner in the drying is if required at depends on the kind of glueing agent utilised and time said drying operation may take in particular ho the drying is performed very easil by natural cooling of the hot melt af er sometimes a jet of compressed air is required to speed u the drying in the case of toilet to last applicator actuated manually or Any suitable or non be the method according to the presen invention is not ed to the use of one applicator with one nozzle It often in particular the on which the to be is wound very to applicator with or several applicators with one or more I to be understood that all those possibilities are within the scope of the present method performed in or It is of no in connection with the present invention how the is towards the log be towards the applicator may be moved the l or even the applicator and the log be moved one toward the tail sealing according to the present invention performed in any of the manufacture of the after has on in the of toilet the tail sealing is preferably performed befor the log is cut the separate present invention has been described herein with reference to is readily understood that the method of tail sealing can be applied also to other suitable certain plastic present invention now with reference to accompanying linited by those show logs the thereon a agent various and 2 an the of the method according to the presen each a on wound a the tail of which ie sealed by a agent She of sinusoids the pattern of is a the pattern of triggered continuous and continuous or She apparatus in 2 one possibility for the performance of the It is constituted by conveyo 4 of a rewinding and applicator log oa which 6 on conveyor 4 applicator which the glueing in such a tha pattern 7 insufficientOCRQuality
