Techniques involve a machine system for producing or treating synthetic threads, comprising a plurality of machine components, having actuators and/or sensors, that are associated with a plurality of control components. The control components are connected by a machine network to a central machine control station. In order to remedy process disruptions as quickly as possible and to ensure uniform product quality, the control components are coupled in parallel to a central analysis station by an analysis network.

The invention relates to a cooling apparatus and a method for cooling a continuous strip, wherein the cooling apparatus comprises a cooling drum and a guiding device for guiding the strip in a plurality of windings around the cooling drum, wherein the guiding device comprises first and second guiding elements, wherein each one of the first guiding elements forms a set with one of the second guiding elements, wherein the first guiding element of the set receives the strip from a first winding in a first winding direction and directs the strip in a first transition direction towards the second guiding element which receives the strip in a second transition direction and directs the strip into a consecutive winding in a second winding direction, wherein the first transition direction is different from the first winding direction and the second transition direction is different from the second winding direction.

The invention describes the use of magnetic platelet particles as a multifunctional additive to various formulations of polyolefin plastic films usable to fabricate packaging and to provide said packaging with similar barrier properties as aluminium metallizations or other gas barriers, with the added benefit of allowing separation and recovery of the packaging by magnetic means. Such novel additives, films and packaging are environmentally friendly and food-safe, so that after use they can be either recovered for reuse, composted, or dumped in the environment to biodegrade. The invention comprises various types of films comprising the additive and methods to improve the properties of said films.
