An Apparatus And A Method For Hemming Edges Of A Tubular Bag And A Tubular Bag
Abstract: Apparatus, method for hemming edges of tubular bag of woven fabric of PE/PPE or HDPE material involving opening, folding, and thermally fusing edges at a cut end of a tubular bag (1) made from woven fabric, and a tubular bag. The apparatus comprises a pre- opening unit (F), a mouth folding unit (G), and a thermal fusion unit (H) positioned sequentially. Each unit (F, G, H) has a suction mechanism 10 (13a,13b,13c) placed above top layer (21a) of the bag (1) for opening the unsealed end (2a); a linear guide mechanism (15a,15b,15c) to actuate the suction mechanisms (13a), a support bed (22a,22b,22c) facilitated with suction mechanism and provided under a lower layer (21b) of the bag (1), and a perforated plate (16a,16b,16c). Layers (21a,21b) are separated (pre-opening unit 15 F) at open end (2a) followed by creating inward folded edges (12) at folding unit (G), and heat fusing them at the thermal fusion unit (H).
