LABELLING 35 PET planet insider Vol. 16 No. 06/15 www.petpla.net and refining of gherkins. The range extends from the use of cranberries and raspberries right through to crea- tions involving other varieties of fruit. These are harvested at the peak of their ripeness, processed carefully and packaged when they are aroma- fresh. As far as Jütro is concerned, sauces and dressings which used to act as a weighty “top-off” ingredient are becoming ever more important. Today they are presented in a guise that stimulates the appetite, in a tasty and fresh, one might almost say “cheeky” format. On offer are noodle, rice and barbecue sauces, as well as dressings and stocks, and even clas- sic Bolognese or exotic curry sauces offering a taste of Thailand, gher- kin relish for steak or a fresh Italian dressing to go with your salad. These speciality sauces are also available in practical cardboard packaging as well as in plastic bottles. Labatta with new design On one of these plastics lines 120 PP and PET bottles with vol- umes of 250ml, 300ml and 500ml are filled every minute and fitted with two each pre-cut paper wet glue labels which are attached to the front and rear of the bottle. This line has now been equipped with a new label- ling machine from Gernep, a Labetta 4/3/12 784 2A. Machines in the Labetta series have been proving themselves in all sectors over many years and are undergoing further technical develop- ment. Due to the use of brand name components in drive and control appli- cations, the customer are assured of a high level of machine availability. The space-saving, compact rotary construction with precision bottle feed, together with the tried-and- tested wet glue labelling in high end technology, ensures meticulous label presentation. The table control cam is maintenance-free and divided up into segments, a special overlay gearbox handles the precise positioning of the label. The multifaceted machine with in-situ label magazines ticks all the right boxes when it comes to traditional requirements in terms of features. The combination of tried-and -tested techniques makes this label- ling machine stand out in its perfor- mance class. The entire complement of electrics for drive, servos, photo- electronic alignment and camera systems is clearly arranged and integrated in a maintenance-friendly way. Separate, space-intensive switch cabinets and control cabinets are not necessary. The machine at Jütro is presented in the new design incorporating protective encapsulation with corner pillars and safety doors which, in this project, are featured on all 4 sides to act as a lift guard. Cold glue labelling With the newly developed wet glue unit, the people at Gernep are setting standards in compactness, ease of maintenance and operator comfort. As always, the adhesive glue pallets are resistant to wear, individually interchangeable and readily adjustable for optimum adhe- sive action. The stainless steel gluing roller and the split glue scraping knife have shown themselves over a number of years to be ideal for glue metering and the gearbox which is encased in oil has likewise proved itself. The “No bottle – no label – no glue” automatic system is standard on the machine as is the mainte- nance-free, heated glue pump. Now this unit has been new designed, is hermetically sealed so that it is splash-resistant as well as being constructed to be more operator- and maintenance friendly. Possible equipment Thanks to the fact that the dimen- sions of the magazine have been kept to a minimum and due to a perfected system of connectors it is possible to achieve very small intermediate distances as regards the positioning of the labels – the precondition for meeting sophisticated design require- ments. This represents a flexible approach to attaching labels to the body, shoulder and rear of the bottle, full neck labels, champagne bows, clip-lock closure and closure safety label. Currently only one shoulder and one rear label are being applied at Jütro but “we are already planning to affix self-adhesive labels. From a technical viewpoint, the machine is perfectly set up for this already”, says Retzke. Operation / Maintenance The console is ergonomically integrated in the upper section of the machine at a distance which makes it easy for the operator to view and make any necessary interventions. The entire machine is controlled by means of a touch screen incorporat- ing up-to-the-minute microelectron- ics. The data relating to the current operation is displayed constantly. Performance information, parameter settings and the causes of any faults are displayed in a text box. Robust and flexible The technical specialists at Jütro had been looking for a machine that featured reliability and, primarily, flexibility in terms of format changes. “Then, a year ago, we came across the Gernep Labetta at the Anuga FoodTech. The servicing aspect helped convince us, as well as the fact that it was realistically possible to carry out a format change within ten or 15 minutes. The machine also impressed us with its robustness, solidity and reliability.”, explains Tech- nical Director Retzke. Although the bottle formats are changed only every three or four days “we nevertheless have specialists in production and bot- tling machine technology who know exactly how to go about manufactur- ing and packaging a delicate mayon- naise or sensitive sauce hollandaise. We also have a special three man team that is responsible for upgrading the lines whenever we have format changes. If, with nine lines, every change of format were to take hours, the line would be at standstill for far too long. With the Gernep Labetta this can be done quickly: the equipment features a number of integrated inno- vative technologies such as the fact that the format components can be replaced very quickly but still without any compromises as regards preci- sion adjustment. And nothing bends or goes out of shape because every- thing is designed to be robust. We are really very satisfied with the machine“. www.gernep.de/en
