Abstract

Un procédé permet de fabriquer un récipient du type plateau. Il consiste à couper et fendre une tige de bambou (1) selon son axe en plusieurs tronçons, de façon à obtenir plusieurs segments de bambou allongés (4), puis à joindre ces derniers pour former un laminé de bambou (5), et à découper ce laminé en fines lamelles de bambou (6) pour former un récipient tel qu'un plateau avec ces lamelles, par les moyens appropriés tels que pressage, coupe et collage. Ce type de récipient consitué de lamelles de bambou (6) comprend des parties de bambou à fibres denses et épaisses qui sont disposées en alternance. Une lamelle de renforcement (10) peut de préférence être collée sur l'avant ou l'arrière des lamelles (6). De plus, dans un tel cas, on peut obtenir la résistance souhaitée pour un récipient même si cette lamelle de renforcement est constituée d'un bois autre que le bambou.
