Abstract (en)
[origin: EP2179828A1] A columnar cork (1) made through compression molding process of a lot of cork granules (1a) mixed with binder resin (1b). The cork (1) is made by being compressed in a direction normal to its longitudinal direction (L) in the compression molding process. The columnar cork (1) is produced by kneading cork granules (1a) and binder resin (1b) to make a kneaded mixture (10); charging the mixture (10) into a molding cavity (30) which is formed by a plurality of divided mold dies (31-34) on a molding base (21) surrounding the molding cavity (30); and compressing and molding the mixture (10) to form a columnar structure (10A) by sliding the plurality of divided mold dies (31-34) in such a direction to narrow down the molding cavity (30) on the molding base (21), thereby solidifying the cork granules (1a) with the binder resin (1b).
