Method for manufacturing a cellular venetian-blind material

摘要

It consists in: a) continuously folding a continuous length of material 40 which is flat, thin and flexible; b) applying an adhesive material longitudinally along the length of tubular form; c) stacking the continuous length of tubular form on a frame 14; d) allowing the adhesive material to adhere one layer to the other in order to form a unitary stack on the planar surface; e) cutting a straight section from the unitary stack and removing it from the frame; f) folding lateral-edge parts 43, 44 of the material; and g) allowing the lower face of the central part to adhere to the folded lateral-edge parts by means of the adhesive. Of use for the windows of buildings.
