Features and applications
They are widely used in the packaging sector, in particular in packaging using plastic films and in the paper converting sector for the handling of sheets of paper.
The labyrinth moulded onto the support surface of the vacuum cup ensures a more effective grip on the product to be handled; in particular, the notches allow even distribution of the vacuum on the surface of the product, preventing the packaging sheet or bag from being sucked into the vacuum cup and becoming deformed.
The high labyrinth (L) also allows for even higher grip values between the vacuum cup and the product.
