る。 Next, an outline of an embodiment of the process of forming the pad material of the sheet cushion according to the present invention will be explained with reference to FIGS. 2 and 3. First, urethane foam, etc. A predetermined amount of an elastic chip 2' made of an unvulcanized small piece of synthetic resin material is inserted. A suitable binder may be added to the elastic chip 2' to increase the adhesive force.
Next, the elastic chip 2' inserted into the lower mold 12 is heated and pressed into a desired shape by the upper mold 13 and the lower mold 12 under predetermined hot pressing conditions to form the lower elastic body 2. A plurality of protrusions 13a are formed on the upper mold 13 at appropriate intervals, and the protrusions 1
3a, a recess 7 is formed in the part facing the protrusion 13a of the elastic chip 2' inserted into the lower mold 12, and this recess 7 is crushed more strongly than other parts. Therefore, this protrusion 13a
The recessed portion 7 formed by being crushed by the lower elastic body 2 is formed to be harder than other portions of the lower elastic body 2. The hardness of the recess 7 can be adjusted as appropriate depending on the size of the protrusion 13a and the clearance of the mold.
