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: The invention relates to an unidirectionally-oriented film comprising a thermoplastic polyester and a polycarbonate. The unidirectionally-oriented film may further comprise an anti-blocking agent and/or a slip agent. Depending on its width, the films of the invention may be used for food packaging; it may be used for strapping cartons, boxes, pallets, textile bales; and it may be used for woven tape fabric. The fabric woven from films of the invention may be used for making sacks, flexible intermediate bulk containers, hot fill jumbo bags for materials such as bitumen, PVC coated fabrics for flex signage, carpet backing, geo textiles, geogrids, metallised fabrics, and self-reinforced composites.

Abstract: The invention relates to a tape comprising from (i) about 75 wt % to about 99.9 wt % of a thermoplastic polyester, (ii) from about 0.1 wt % to about 25 wt % of a linear low-density polyethylene and (iii) from 0 wt % to about 5 wt % of other components, said tape having a thickness from 5 ?m to 300 ?m and a width from 0.5 mm to 7 mm. This tape shows no twinning and sticking to other tapes after slitting, has very good mechanical properties. When the tape is wound, bobbins having a regular shape can be obtained.

Abstract: A polymerization autoclave for the suspension polymerization of vinyl compounds in the aqueous phase having a volume of from 50 to 200 m.sup.3, an impeller agitator driven from below at the bottom of the autoclave and two cylindrical displacement bodies acting as flow interrupters, secured downwardly from the autoclave dome, where the autoclave has a height-to-diameter ratio of from 2.4 to 3 with a critically dimensioned agitator and critically dimensioned flow interrupter fittings. By the use of this invention in the case large-scale autoclaves, the heat of polymerization can be removed merely by wall-cooling. The autoclave according to the invention are very economical, as shown by, for example, a spatial capacity of 0.3 to 0.4 metric tons of polyvinyl chloride per m.sup.3 autoclave volume.
