The invention relates to a method and a device for applying a shrink film sleeve (1) to a container (9). The method comprises the following steps: a) perforating of the shrink film sleeve (1) at predefined distances, b) expansion of the perforated shrink film sleeve (1) by means of an expansion device, in particular an expansion mandrel (3), c) transporting of the expanded shrink film sleeve (1) along the expansion device (3) having a conveyor roller pair (4a, 4b), d) tearing off of the shrink film sleeve (1) at the perforation with a downstream dispensing roller pair (5a, 5b), the transport speed (V tearing off) thereof being at least temporarily larger than the transport speed (V conveyor) of the conveyor roller pair (4a, 4b) and e) depositing the separated shrink film sleeve (1) onto the container (9).
摘要:
A film has a skin layer, a base layer, and an intermediate layer between the skin and base layers. The skin layer has styrenic block copolymer, the base layer has ethyiene/alpha-olefin copolymer, and the intermediate layer has from 12% to 50% styrene/ethylene-butadiene/styrene block copolymer. The film has a free shrink at 90°C of at least 65% and a density of at most 0.960 grams per cubic centimeter.

The invention relates to a device and to a method for attaching a flexible, profiled hollow cylinder (1) on a cylinder-shaped body (2). Profiled hollow cylinders that are attached to a cylinder-shaped body provide excellent modules for radiating fluid media with electromagnetic radiation. The object of the present invention is also a method for producing radiation modules and radiation modules produced by the method according to the invention.
摘要:
A pipe from a plastic material having memory properties is extruded. The extruded pipe is cut to form a pipe part (7). The pipe part (7) is warmed and the end (6b) of the pipe part (7) is bent. The pipe part (7) forms a clamping ring (6) and the bent end (6b) of the pipe part (7) forms a stop edge (10) in the clamping ring (6).
