The development of this technology stems from the specific requirements of a client who needed to produce two dif- ferent containers on the same machine and from the same preform: jars (with a neck diameter from 60 to 85mm) and bottles (with a neck from 30 - 38mm) and to maintain a high level of productivity, from 8,000 to 9,000bph. The Italian manufacturer has developed a system of blow- ing which allows the use of the same machine to obtain both bottles (with a neck from 30 - 38 mm and wide-mouth bottles and jars (60-85mm) from the same preform. The company calls this process “blow-trimming”. In a first blow- ing phase the neck is made wide-mouth in a second phase a cut is made at the top of the container (dome) with the narrow neck. A detailed study of the preform and of the process is required in order to:  minimise the weight of the neck and the “dome”;  facilitate the cutting phase and reduce the amount of material cut  obtain a good formation of the thread in order to ensure the seal with the cap  ensure high consistency of the thread with the appro- priate weight of the neck for a perfect grip and neck resistance. The new technique allows the production of containers from 250ml to 1000ml with neck finishes from 30 to 85mm. www.siapi.it Bottles - , container - and case drying equipment Gesete GmbH, Germany, will be presenting drying equipment for packs; the bottle drying plant Compaktline LK for the small to medium-sized performance range; the Highline bottle and container drying plant for the discern- ing user as well as for the higher performance range and the Compaktline K for drying boxes and other types of end packaging. In addition to the energy-efficient blower tech- nology and bottle drying facilities the company will also be presenting the new Labelblow blow-off system. Accord- ing to Gesete, during blow-off of plastic sleeve labels on PET deposit bottles energy savings of up to 85% can be achieved by comparison to other systems can be achieved due to the special nozzles. www.gesete.de Gesete Hall 7 | Booth 320
