The company claims that the new product takes up less floor space than separately mounted machines, simplifies deployment in an extrusion line, and provides easier access for replacement of filter media. The concept was originally developed at the request of one of its customers but it can be applied with equipment custom designed by Nordson Kreyenborg for other companies, including extrusion processors, compounders, and recyclers. The cart is mounted on fixed casters that permit transverse- direction movement into and out of the extrusion line, while precisely aligned movement in the extrusion direction is pro- vided by floor-installed rails. Linear guides on the cart permit independent extrusion-direction movement of the gear pump and screen changer. In order to save space facilitate access for changing screens, the gear pump has effectively been turned onto its side so that its drive can be mounted below the pump. Coolant can be either air or demineralised water and its rate of flow is adjustable. www.nordson.com www.kreyenborg.com Precision without barriers Intravis, Germany, supplier of quality inspection sys- tems for the plastic packaging industry, presents a new development for its Sample PreWatcher. This system, first introduced to the market in 2009, is by today the standard system for high precision preform inspection and meas- urement in the plastic packaging industry. Optionally, the Sample PreWatcher is now able to visualize and determine barrier layers in preforms helping to optimize packages for sensitive beverages. The device is in use already in the market. www.intravis.com End of the line Sipa’s new gen- eration of Digipac pallet stretch-wrapping equip- ment is designed to pro- vide a compact, flexible, and cost-efficient solu- tion on bottle packag- ing lines, the company says. The range, which comprises the Orbiter rotating pallet and Cinetic rotating arm, is claimed to be easily installed on lines run- ning with conventional or robot palletisers. Cinetic’s film unwinding arms are mounted on a rotating platform that is anchored to the ground and turns around the fixed pallet. It is available either with one or two rotating arms, and is capable of wrapping up to 120 pallets/h. The Orbiter stretch-wrapping units, which rotate the pallet, are capable of handling up to 50 pallets/h. Sipa’s “Matrix” system, in which the film unwind- ing arms are mounted, is claimed to be robust and stable, with a rigid and balanced construction. Finished pallets exit at 90° to the line, without the need for a turntable. An impermeable top sheet can be positioned by the optional Fast-cover. The Pre-cover option can be used for special requirements or to achieve a double pallet cover. The St- unit device pre-stretches the film by as much as 320%, depending on the speed of the operation and product needs. Cutting and welding of the end of the film is per- formed by Cs-unit. www.sipa.it LSP PET recycling process After an R&D period of more than 30 months, NGR (Next generation recycling maschinen) GmbH, of Feld- kirchen, Austria, has launched a new process for PET recycling which focuses on increasing the IV value and decontamination of the material. The decontamination service is carried out impartially by a third party in a chal- lenge test. The test results form the basis for approvals in the food industry. NGR’s LSP process aims to use the higher rate of reaction in the melt phase to save energy and time during PET processing. The processing unit used in lab testing had an output rate of only 70kg/h. A production unit with an output rate of 380kg/h was designed and put into operation in Autumn 2013. The processing method was the subject of frequent discus- sions with a number of European and American PET pro- cessors, and the concept was well received, according to NGR. The new process has been developed for process- ing PET from industrial waste, fibres, bottles, preforms, films and washed post-consumer-flakes. www.ngr.at
