2. Description of the Related Art In recent years, tobacco with a light taste has been desired, and therefore, a cigarette is usually provided with a filter at one end thereof. With these cigarettes and filters,
These pieces are connected to each other by winding a piece of glued tip paper, and the connection of the filter to the cigarette is performed by a filter attachment device, a so-called filter attachment.

[0003] This filter attachment is provided with a wrapping portion for a tip paper piece. The wrapping portion includes two cigarettes having a filter plug disposed at the center thereof and a glued tip paper piece. Are supplied respectively. In the winding section, a tip paper piece is wound around two cigarette and filter plugs, and these connections are made. Thereafter, the two filter cigarettes connected by the tip paper piece are combined with each other. Cut from the center of the filter plugs into individual filter cigarettes.

On the other hand, an apparatus for supplying chip paper pieces to a winding section is provided with a transport path for guiding chip paper fed from a roll toward the winding section, and the transport path includes an upstream path. A gluing device and a cutting device are sequentially arranged from the side. The gluing device transfers the glue to one surface of the chip paper and forms the glue.On the other hand, the cutting device cuts the glued chip paper into pieces each having a predetermined length, and cuts the chip paper. After forming the paper piece, the chip paper piece is supplied to the winding section.

[0005] Further, the supply device for the chip paper is provided with a heating device at a portion of the transport path located upstream of the gluing device, and the heating device is configured to apply the chip material before the gluing to the chip paper is performed. It heats the glued surface of the paper. If the tip paper is heated before being glued in this way, the glue applied to the tip paper pieces is then dried by receiving heat from the tip paper. It is possible to prevent the adhesive from protruding from the chip paper piece, and it is possible to stably wind the chip paper piece by increasing the initial adhesive force of the adhesive. If the pre-drying of the glue is not performed effectively, the winding of the chip paper piece will be defective, causing air leaks, and the glue that has protruded will become slime and the appearance of the product will deteriorate. Will be done.

[0006]

By the way, the above-mentioned heating device is constructed by embedding a heater in a roller for defining a conveying path, for example. This roller directly heats the paste of the tip paper. Rather, since the tip paper before gluing is heated, it is difficult to properly heat the tip paper. For example, if the heating of the tip paper is insufficient, the tip paper cools before the gluing, and the pre-drying of the glue after this is not sufficiently performed, and conversely, if the heating of the tip paper by the rollers becomes excessive. In addition, it is difficult to control the heating temperature of the roller, and the pre-drying of the paste cannot be performed effectively, for example, the tip paper is warped and the winding failure is likely to occur.

On the other hand, it is conceivable to dispose a heating roller with a heater downstream of the gluing device.
The heating roller performs heating and drying of the paste via the tip paper from the surface opposite to the gluing surface. In this case, too, the heating and drying of the paste cannot be performed directly. Pre-drying cannot be expected. The present invention has been made based on the above-described circumstances, and an object of the present invention is to provide a tip paper supply device of a filter mounting machine capable of effectively and reliably performing preliminary drying of a paste applied to a tip paper. Is to provide.
