Abstract (en)
[origin: WO9627150A1] A camera bellows comprising a substantially rectangular, tubular body having two ends, the walls of which are provided with folds for extensibility, said folds extending perpendicularly to the longitudinal direction of the body, and reinforcements for retaining the rectangular shape of the bellows, wherein alternating elastic and rigid folds are provided, said elastic folds enabling transverse displacements of one end of the body relative to the other whilst the rigid folds serve to retain a free optical path through the bellows during said displacements. The invention also relates to a method for producing the above described camera bellows, said tubular body being formed by folding a sheet comprising a lustreless non-reflective inner lining, a weather-resistant outer lining and reinforcement strips laminated therebetween on fold surfaces adjacent to the folds, wherein said elastic folds are obtained in that the fold-surfaces of such a fold are free of reinforcement strips and that said inner lining and outer lining are made of elastic materials.
