BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for drying an adhesive material applied to the back surface of a carpet, and more particularly to a carpet drying device specially ordered for a large hall such as a hotel lobby.

[0002]

2. Description of the Related Art For a carpet to be laid on the floor of a large hall such as a hotel or a conference room, a carpet that is specially ordered has a side of 10 meters or more, which is extremely large. This carpet is
It is manufactured by drawing a pattern sketch on the base cloth and planting pile yarns of various colors with a hook gun along the sketch. The base fabric on which the pile threads are planted has a latex composition adhesive applied to the back surface so that the pile threads do not come off. The adhesive applied to the back surface of the base cloth is dried by blowing hot air with a jet heater. However, the jet heater cannot uniformly and efficiently dry a large carpet. For example, it takes a few days to dry a 10 × 10 meter carpet.

[0003] Various structures have been developed as a drying device for a carpet that is continuously produced in a fixed width, rather than a specially ordered carpet. For example, a device for drying an adhesive applied to the back surface of a carpet is disclosed in Japanese Patent Laid-Open No. 61-2.
It is described in Japanese Patent No. 66682. This device has a structure in which a latex composition is applied to the back surface of a base fabric on which pile yarns are planted, and while being conveyed by a belt conveyor, it is heated and dried from below. The drying device having this structure can be conveniently used in a device for continuously producing carpet.

Further, Japanese Patent Laid-Open No. 60-52682 describes a device for pressing a sheet coated with a hot melt resin onto the back surface of a base cloth on which pile yarns are planted by a roll.

[0005]

[Problems to be Solved by the Invention] JP-A-61-2666
The drying device described in Japanese Patent No. 82 cannot efficiently dry a specially ordered large carpet. This is because the device conveys the yarn-implanted base fabric on the conveyor above the dryer. Further, in this drying device, a heater is arranged below the carpet. The heater arranged below can efficiently heat the carpet. However, for example, when a large carpet having a side of 10 meters is dried from the lower surface, the center portion and the peripheral portion are significantly unevenly dried. This is because a large amount of steam that is heated by the heater and is generated in the central portion of the carpet cannot be quickly removed.

In the apparatus disclosed in Japanese Patent Laid-Open No. 60-52682, a sheet coated with hot melt resin is pressure-bonded to the back surface of the base cloth, so that a large carpet having a width of 10 meters is not manufactured. Actually impossible.
This is because the hot melt sheet is pressure-bonded with a long pressure roll having a total length of 10 meters or more.

The present invention was developed with the object of solving these drawbacks of the prior art. An important object of the present invention is to make it possible to efficiently and uniformly dry a large custom-made carpet in a short time. To provide a drying device.
