ALPMA wraps many more cheese types using LinMot
ALPMA has mastered the film wrapping of packs of soft cheese , even if the product properties fluctuate and the product types change frequently . The new MultiSAN film wrapping machine packs round and rectangular soft cheese without compromise , as well as cheese in square , cylinder or halfmoon format . Complex conversions or long set-up times are no longer necessary .
Previous packaging machines in widespread use in cheese dairies have been mechanically driven with shafts , cams and gears to synchronise the movement of the individual movements . This solution was fine for packaging one type of product .
The packing many different types of product with folding or wrap-around required a more flexible solution .

The envelope fold at the bottom of the cheese , which is typical for the wrap-around packaging , is now generated with the help of four horizontally mounted LinMot

linear motors , each of which drives a sealing lamella via a linkage . After the cheese has been wrapped in packaging film by the machine and fixed on a round plate by tongs , the lamellas press the protruding film together in quick succession on the underside of the product so that the desired fold is obtained .
“ Only the LinMot motors have shown the required performance with the small dimensions we wanted ,” reports Helmut Eitermoser , the designer of the MultiSAN .
PS01 – Linear motors . The MultiSAN uses motors of the type PS01-23x160H-HP-R which can delivery up to 130N with strokes from 20 to 780 mm . A 120 mm , version was chosen for the MultiSAN .
With a cylindrical design of only 23mm ., these LinMot motors achieve an extremely high power density .
Always optimal packaging results
“ We have also used the very sensitive and direct reaction behaviour of the LinMot linear motors to give the operator a tool to react to fluctuations in the product consistency ,” adds Helmut Eitermoser .

Machine sales doubled With these features , the new packaging machine from ALPMA has hit the nerve of the market , as the sales figures impressively demonstrate : In the first few months after the machine was launched , they were twice as high as the usual orders in the same period .
