Abstract: A bag for loose material, wherein the bag is formed from a tubular material, which tubular material is a tubular planar assembly or a flat material connected to form a tube, and has a first and a second open end. Sections of the tubular material of one of the ends are shaped by folding to form a bag bottom. The bag bottom exhibits a first cover sheet and a second cover sheet. The first cover sheet is connected to the bag bottom and extends in a first region of the bag bottom. The second cover sheet is connected to the bag bottom and extends in a second region of the bag bottom. Via the cover sheets, the folded sections of the tubular material are held together in such a way that the bag bottom is sealed.

Abstract: Cutting device for longitudinally cutting a film web, in particular a plastic film web, moved in a web plane in a transport direction into a plurality of film bands, wherein a first cutter bar provided with cutting blades is immersed with the cutting blades in a cutting position into the web plane. In order to replace the cutter bar, a second cutter bar provided with cutting blades may be immersed with its cutting blades into the web plane, wherein the first cutter bar may be moved from the cutting position into a transfer position outside of the web plane when the second cutter bar is immersed with its cutting blades into the web plane.

Abstract: A coated fabric includes a fabric from monoaxially drawn polymer tapes, in particular polyolefin or polyester tapes, preferably polypropylene or polyethylene terephthalate tapes. The fabric is coated with a sealing layer from a thermoplastic synthetic material the melting point of which is below the crystallite melting point of the fabric tape material. The coated fabric is excellently suitable for hot-air, ultrasonic, heated tool, infrared or laser beam welding.

Abstract: A process produces web sections from a flexible web material. The flexible web material is provided with tear-off lines at the distance of the length (L) of the web sections to be formed, which tear-off lines weaken the web material but do not bring about a complete separation of the web sections from the web material. The web sections are separated from the web material along the tear-off lines by tearing. The web material comprises a fabric made of small stretched plastic bands, and the tear-off lines are produced by laser beam processing.
