Diffusion Device Abstract In the representative embodiments of diffusion devices disclosed in the specification, a diffusor support member (1) and a flexible sheet-like diffusor (2) are connected in sealing relation along peripheral edges (3) by continuous clamping and sealing arrange- ments (4). One form of the clamping and sealing ar- rangement comprises a U-shaped clamp (31) which em- braces the edge of the support member (1) and the peripheral edge (3') of the diffusor (2). In another form of clamping and sealing arrangement, two strip members held apart by a third strip are inserted into a groove in the support member so as to clamp the diffusor in the groove. Additional strengthening members for the support member and hold-down members (34) for the diffusor are also disclosed. (Fig. 12)
