Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a cloth folding mechanism. Background Art

[0002] Underwear is often worn next to the body. Since it is worn inside clothes and not exposed outside, it should be comfortable and convenient. Figure 1 As shown, the briefs 100 are generally provided with elastic bands at the waist and leg openings, and the material of the briefs is mostly pure cotton, so the underwear is generally made by sewing. Because of the setting of the elastic band, it is usually stretched during sewing. After the sewing is completed, the elastic band shrinks naturally, causing the fabric joints to shrink and wrinkle. When folding and sewing the briefs 100, the briefs 100 must be folded along the center line 200. If the corners are not easy to align, the fabric will be clumped or have gaps, affecting the appearance and comfort. When sewing by hand, the above problem is not big because it can be flattened manually, but if mechanical automated processing is to be achieved, this problem must be overcome. Utility Model Content
