Winding section in a slitter winder for a fibrous web and apparatus for bringing a fastening means onto the surface of a partial web

#This application is a U.S. national stage application of International App. No. PCT/FI2010/051054, filed Dec. 17, 2010, the disclosure of which is incorporated by reference herein, and claims priority on Finnish App. No.U20090469, filed Dec. 22, 2009.

#Not applicable.

#The invention relates to a winding section of a slitter winder for a fibrous web in which an apparatus for bringing a fastener onto the surface of each partial web is arranged along the path which the partial web travels before the winding section. The invention also relates to an apparatus for a slitter winder for a fibrous web for bringing a fastener onto the surface of a partial web.

#In the following, the invention and its operation will be explained with reference to the appended schematic drawings.

#FIG. 1 shows schematically a winding section in a slitter winder for a fibrous web according to an embodiment of the invention

#FIG. 2 shows an apparatus according to an embodiment of the invention in the maintenance position.

#FIG. 1 shows schematically a winding section 10 in a slitter winder for a fibrous web. The FIG. shows a drum reel-up, where web reels 12 to be wound from partial webs w′ are formed supported by a drum 14 and support belts 11. The support belts are represented only by one part of a single support belt. The type of the winding section may also be different.

#After the winding of each set, a fastening means, preferably an adhesive, attaching the web tail to the reel is passed onto the underside of the partial webs the underside facing the inside of the reel. For this purpose, there is an apparatus 20 arranged in conjunction with the winding section of the slitter winder for bringing the fastening means onto the surface of each partial web. The fastening means may be, for instance, a double-sided tape, but glue is particularly advantageous in practice. Since the fastening means is preferably an adhesive, the apparatus may also be called a gluing device 20 in this connection. The gluing device comprises an applicator head 22 for applying the adhesive, which applicator head is arranged to move substantially in a cross-direction with respect to the travel direction of the web, across the partial webs w′ for passing the adhesive onto the web surface. The gluing device 20 comprises a first guiding structure 26, in which the applicator head 22 is arranged. The applicator head can be moved along the first guiding structure 26 across the partial webs. Thus, the adhesive may be passed onto the surface of each partial web by means of the applicator head. The adhesive is passed onto the web surface at the final stage of the winding in order to fasten the tail of the cut-off web onto the web surface and/or to fasten the new web to the core base, such as a sleeve, of the reel.

#Support members 24 are arranged in conjunction with the winding section, by means of which members the gluing device 20 is arranged movably substantially in cross-direction with respect to the winding section. In this manner, the gluing device 20 can be moved from beneath/inside the winding section 10 to the side thereof for maintenance and thereby the maintenance work can be performed much easier. Locking members 30 are also arranged in conjunction with the apparatus, by means of which members the first guiding structure 26 of the apparatus can be locked at least into its operating position in the slitter winder. The locking members may be embodied in several ways and FIG. 1 shows, by the way of example, a solution, in which the parts are interlocked by means of a separate pin.
