Fabric bag manufacturing device, has opening mechanism including material layer separating and folding unit for separating and folding material layers, which are foldable away from each other, so that bottom lies in plane of tube pieces

摘要

The device (1) has a transport equipment for transporting tube pieces in a transportation direction (X), and running transverse to an extending direction (Z). The tube pieces are conveyed in a horizontal position, and an opening mechanism is provided for opening an end of one of the tube pieces to form bottoms. The opening mechanism includes a material layer separating and folding unit for separating and folding material layers, which are foldable away from each other around 90 degrees, so that the opened bottom lies in a plane of the tube pieces. An independent claim is also included for a method for manufacturing a bag from tube pieces.
