Abstract
A process and system for manufacturing roller blinds is provided which includes structure for performing plural steps including a first step of helically winding slat fabric about a drum, thereby forming a slat product. A second step includes moving the slat product from the drum to a platform. A third step includes winding the slat product about a roller tube to form a roller blind. A fourth step includes moving the blind from the platform to a heat treating device.
Claims22
A method of manufacturing a blind including a roller and a covering material, the covering material being formed by overlapped layers of fabric, the method comprising:
- helically winding fabric about a drum to form the covering material formed by the overlapped layers of fabric, the covering material including one or more cells;
- attaching the roller to a top end of the covering material;
- winding the covering material about the roller;
- and
- heat treating the blind to set a wound shape into each layer of the overlapped layers of fabric.
A method of manufacturing a blind including a roller and a covering material, the covering material being formed by overlapped layers of fabric, the method comprising:
- helically winding fabric about a drum to form the covering material formed by the overlapped layers of fabric;
- attaching the roller to a top end of the covering material;
- winding the covering material about the roller;
- and
- heat treating the blind to set a wound shape into each layer of the overlapped layers of fabric;
- wherein a first adjacent layer of the overlapped layers of fabric forms a front surface of a first cell and a rear surface of an adjacent second cell.
A method of manufacturing a blind including a roller and a covering material, the covering material being formed by overlapped layers of fabric, the method comprising:
- helically winding fabric about a drum to form the covering material formed by the overlapped layers of fabric, the covering material including one or more cells therebetween;
- attaching the roller to a top end of the covering material;
- winding the covering material about the roller;
- and
- heat treating the blind to set a wound shape into each layer of the overlapped layers of fabric;
- wherein the wound shape includes a concave curvature.
