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.

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: The device for cooling an adhesive applied to a surface of bag bodies includes a transfer conveyor and a cooling conveyor. The transfer conveyor conveys the bag bodies at a transfer speed to the cooling conveyor, and the cooling conveyor conveys the bag bodies taken over from the transfer conveyor at a cooling conveyor speed. The transfer speed is higher than the cooling conveyor speed, which is why the bag bodies are arranged overlapping each other on the cooling conveyor. Due to this higher packing density, there is achieved a long dwell time of the bag bodies in the cooling conveyor at simultaneously a high flow-rate of bag bodies through the device.

Abstract: A circular weaving machine has warp-tape guide elements arranged around a circular reed to supply a multiplicity of warp tapes. Weaving-shed forming devices group the fed warp tapes into two warp-tape groups and impart thereon mutually opposed alternating movements, with the result that a weaving shed is opened and closed between the two warp-tape groups. A weaving shuttle moves on an orbit in the opened weaving shed and, in the process, introduces a weft tape from a weft-tape bobbin carried thereby into the weaving shed, with the result that a fabric is formed. The fabric is drawn off through a weaving ring. The weaving shuttle keeps the bobbin axis of the weft-tape bobbin at an angular position which deviates by at most +/?15°, preferably at most +/?10°, from a normal to a surface which contains the geometric connecting lines between the warp-tape guide elements and the weaving ring.

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.
