[0002] Cord fabric is a textile, usually used to make curtains, door curtains and other home decorations. There are many kinds of materials for cord fabric, such as cotton, linen, silk, polyester, etc. Different fabrics and colors can be selected according to needs. The triangle folding machine is a device used for folding plastic film, mainly used to reduce the width of the film by half for easy packaging. The core component of this machine is an inclined triangular folding frame, usually set in an isosceles triangle. When the film is unrolled and runs to the triangular folding frame, its left and right sides are respectively attached to the two sides of the triangular folding frame, forming a fold line at the intersection, thereby achieving folding.
