was applied, hot air was further applied, and the fiber aggregate was compressed using a net or a caterpillar, and then cooled and the fibers were fixed to produce a sheet-like heat-welded fiber aggregate. Note that the heating time is about several minutes. Further, it is also possible to adopt a configuration in which the net-like body or the like is turned over midway, so that one side is heated first, and then the other side is heated.

Thereafter, it was dipped in a liquid adhesive (natural or synthetic latex), pulled up, and dried to fix the fibers to produce an example product. . In the cushion member 1 of this Example product, as shown in the enlarged explanatory view of FIG.
There is a heat welding part 11 and an adhesive part 12.

。(3) Modifications of Embodiments The present invention is not limited to those shown in the specific embodiments described above, but may be modified in various ways within the scope of the present invention depending on the purpose and application. That is, for example, the aggregate is continuously moved in one direction by a belt conveyor, etc., and during this movement, it is first compressed and thermally welded by a heater, etc., then a liquid adhesive is sprayed, and then a hot air or dry adhesive is applied. Cushion members can be manufactured continuously by drying in an oven and fixing the fibers. In this case, if necessary, cutting can be performed using high frequency or the like after thermal welding. As a method for applying the adhesive, a spray method is suitable for a continuous process, but the method is not limited thereto, and a continuous dipping process can also be combined. According to these continuous manufacturing methods, cushion members can be manufactured in large quantities easily and economically.
