The perforation roller is mounted with rows of toothed circular blades that can be installed at a minimum distance of 5 mm between them. A natural fiber contrast roller supports the cutting process. The Panther 100 can produce slits up to a length of 15mm. The shape, number of teeth and their dimension are tailor-made, depending on the need. The blades can be made of steel, stainless steel and coated with either carbonium or titanium. An integrated Adjusting Penetration System regulates the depth of the blade penetration in the film. The unit is designed to be installed on a hosting machine and it is compatible with all production lines. A roller with few blades is used for applications such as an easy opening system for juices or for precutting nets. More blades are needed for applications such as plastic film for protecting vegetables.
