    • Shaping unit comprising three compartments referred to as "upper", "middle" and "lower" and that are tiered, for circulating the compressed gas necessary for manufacturing a plastic -based cellular structure in a die with parallel slots, in which: - the upper compartment (1) is passed through transversely by at least two pairs of divergent ducts (15, 16), each of said pairs of divergent ducts communicating, in successive alternations and sequentially, with means for injecting a compressed gas and with means for creating a vacuum; - the middle compartment (2) comprises means (M) that communicate with at least the first pair (15) and with at least the second pair (16) of divergent ducts of the upper compartment in order to redistribute the compressed gas and maintain the vacuum respectively to and from the lower compartment (13); - the lower compartment (13) comprises, on its upper face, two rows (20, 21) of tubular channels communicating with the means (M); the means (M) of the middle compartment consisting of two continuous and elongated cavities (17, 18) positioned on either side of the longitudinal axis of said compartment, extending over substantially its entire length and passing tlirough it transversely.
    • 成形单元包括被称为“上部”,“中间”和“下部”并且被分层的三个隔室,用于使制造具有平行槽的模具中的基于塑料的蜂窝状结构所需的压缩气体循环,其中: 上部隔室(1)横向通过至少两对发散管道(15,16),每对发散管道以连续的交替方式连续地连续地连通,用于注入压缩气体和用于产生的装置 真空; - 中间隔室(2)包括与上隔室的至少第一对(15)和至少第二对(16)的发散管道连通的装置(M),以便重新分配压缩气体并维持 分别往下室(13)的真空; - 下隔室(13)在其上表面上包括与装置(M)连通的两排(20,21)管状通道; 中间室的装置(M)由位于所述隔室的纵向轴线的任一侧上的两个连续且细长的空腔(17,18)组成,在其整个长度上延伸并横过其横穿。
