Abstract: Temporary masking ceiling formed by a textile fabric provided with transverse orifices, joined to form open, tubular cavities. The ceiling comprises two identical, superposed sheets (NS, NI), each forming a pattern with polygonal openings, a top sheet (NS) and a bottom sheet (NI), superposed, linked by a curtain of multi-stranded joining yarns (10) along the sides (C1-C6) of the openings (Oi) in order to suspend the bottom sheet (NI) on the top sheet (NS) forming open, vertical cells (Ai).

Abstract: Display case with a geometric surface having a cylindrical structure with a convexly shaped section formed by a carcass supporting a bent panel provided with longitudinal slots and a facing sheet. The slot (5) of the carcass constitutes a fitting slot and the lateral edge of the sheet (7) is provided with a flexible strip (72) forming a fold line (73) at its junction with the body of the sheet and engages in the fitting slot (5) by a part of its length, whilst the remaining part (?L) is able to deform elastically and freely relative to the fitting slot (5) and the structure (1) in order to tense the sheet (1).
