Hinterkopf put several years of development work into the new necking machines N40.2 and N40.3. With 40 workstations, a variable stroke and a production speed of up to 240 cans per minute, they are far ahead of their competitors.
When the N40.2 and N40.3 were ready for serial production Hinterkopf had reached a big goal: All machines of a production line increased their speed from 150 to 240 cans per minute. Therefore, the N40 series differs from its predecessor N30 in a variable stroke and the novel bearing concept with roller bearing - making it more accurate than any other machine of its kind!
40 work stations for higher demands
More and more demanding consumers challenge our customers. Paint, varnish and print combine with a unique design for a unique appearance of the cans. Thus, it is no longer sufficient to form only can shoulder or the neck. Even the can or bottle mantle is drawn deeper and deeper in the decoration. This is achieved by a symmetrical narrowing or widening, which can already start far down on the bottom. Prerequisite are further insertion tools for the mantle. Hinterkopf therefore equipped the N40.2 with 40 work stations - ten more than the N30.
Technical highlights: variable stroke and single drive of the rotary tools
On the one hand, the mantle forming needs a larger stroke, on the other hand, the necking machine has to process cans and bottles of different shape and length so that the maximum stroke is not always tapped. Hinterkopf considers both criteria with a variable stroke - a feature of the new N40.2. The rotating tools, curling, milling and rolling seams or shoulders, are equipped with an individual drive. This allows different speeds of the tools on the respective work stations. As for the production rate, the N40.2 reaches a top performance of 220 cans per minute, the N40.3 even reaches up to 240 cans per minute.
