C 45 Patent ti eySnr. Patent and registration authorities in the United Kingdom and in the Member States 32 33 31 Privilege requested - Begird prlorltet 71 A. The present invention relates to a method of using a core made of cardboard or similar strips by helical winding, the outer surface of which has a thermoplastic material as a winding core, except for the method according to patent When making webs, for example in the paper and textile industries, they are usually wound into cylindrical rolls, in which case a core, usually made of cardboard, is used as the winding core.
Cardboard cores are also commonly used in the further processing of webs. When starting to wind the roll, the end of the web must first be made to grip the core. This is usually done by gluing, in which case glue is applied to the core or to the side of the web facing the core. The end of the web is then passed around the sleeve either by hand or by means of belts, compressed air nozzles or other control means.
The end of the web can also be attached to the core from the outside of the web with nails or pins printed on the core. The use of both running glue and pins causes inconvenience in winding machines.
The object of the invention is to provide a sleeve to which the end of the web can be easily and quickly attached.
The invention is characterized in that the end of the web to be wound is attached to the core by heating a layer of heat-sealing adhesive partially covering the outer surface of the core through the web to a temperature at which the adhesive becomes adhesive and pressing the web against the core. A heating member pressed against the core from outside the web melts the adhesive to provide the desired adhesion.
The adhesive solidifies immediately when the heating element is removed. The coating with an adhesive is preferably carried out in connection with the manufacture of the core. The amount of adhesive applied to the surface of the sleeve is dispensed so as to provide sufficient adhesion to the material to be attached to the sleeve.
The invention will now be described in more detail with reference to the accompanying drawing, in which Figures 1 and 2 show some embodiments of a sleeve according to the invention and Figure 3 a diagram of an application. In Fig. The surface of the sleeve has a plurality of spaced annular adhesive strips 2 of heat-sealed adhesive, the width and spacing of which are selected to provide the desired grip on the web to be wound on the core.
In the application shown in Figure 2, the paper web is wound into a roll in a slitter with two carrier rollers. In the figure, the roll 4 is shown pre-wound, whereby the pusher roller 5 has pushed the roll whose rotational movement has stopped into a position where it is supported 3 by one of the carrier rollers 6, the pusher roll and the support roll 7. The paper web 8 then runs along the circumference of the guide roller 9 between the carrier rollers. The adhesive and the paper web at the heating iron are pressed against the core so that the desired adhesion is achieved.
The invention is not limited to the embodiments shown, but can be modified in many ways, for example so that the adhesive coating forms a spot pattern on the surface of the sleeve. Owner name : A. A method of using a core 1 made of cardboard or similar strips by helically winding with a thermoplastic material on its outer surface as a winding core, except for the method according to patent , characterized in that the end of the web 8 to be wound is attached to the core 1 by partially heating covering the heat-sealing adhesive layer 2, 3 through the web to a temperature at which the adhesive becomes adhesive and by pressing the web against the core.
Method according to Claim 1, characterized in that annular adhesive strips 2 are formed on the outer surface of the sleeve 1 from the heat-sealing adhesive.
Method according to Claim 1, characterized in that the outer surface of the sleeve 1 has longitudinal adhesive strips 3 formed from the heat-sealing adhesive.
