The folding device for the non-woven fabrics provided by the invention has the beneficial effects that a motor drives a driving wheel so as to enable a driven wheel to rotate, so that each conveying roller moves synchronously so as to convey the non-woven fabrics; and the air cylinder can drive a front moving rod and a rear moving rod, so that the non-woven fabrics of the whole swinging mechanism further moves front and back, and a folding effect of the non-woven fabrics is achieved.

The invention discloses a manufacturing method of a composite curtain. The manufacturing method comprises the following steps: 1) material preparation; step 2) covering: flatly paving ta surface composite cord fabric on a bottom composite cord fabric, and then laterally bending and extending the surface composite cord fabric to wrap the side surfaces of bottom sub cord fabrics; step 3) fixation; fixing the surface composite cord fabric and each bottom surface sub cord fabric through a fixing part to form a composite cord fabric finished product, wherein the fixing part can adopt a thread sewing or glue bonding mode for fixing, and when the fixing part fixes the surface composite cord fabric and plane cord fabrics together via sewing, a sewing thread sews the bottom surface of the surface composite cord fabric without penetrating through the surface of the surface composite cord fabric; and 4) discharging. By means of the manufacturing method, composite curtain folding can be achieved,attractiveness can be guaranteed, and product competitiveness is improved.

The invention discloses a rotary display stand for displaying electronic products. The rotary display stand comprises a support frame body; a bedplate is arranged at the upper end of the support framebody; a rotary support device is arranged between the support frame body and the bedplate; and a support folding device is arranged at the lower end of the support frame body. The display stand can be rotated, so that a folding effect is achieved on the basis of supporting; and the display stand can be supported and can also be folded, so that the display stand just occupies small space in the transportation process.
