Summa produces all sorts of cutters, for example for cutting vinyl. The foil is sucked onto the cutting table by Sunon ventilators. Communication with the PC takes place via a Bulgin industrial USB connector.
Summa was looking for a USB connector that was more robust than the ordinary USB flash cards used for computers. The company required a connection from the controller card to the PC. We solved this by splitting this into a Bulgin adapter on the plotter and a cable from the plotter to the PC. This makes the adapter on the cutter extremely strong. Inside it, a small standard cable runs from the controller to the adapter (this cable is internal and need not be special). The cable from the adapter to the PC has a strong Bulgin connector at the point where it enters the adapter and an ordinary USB flash card along the side of the PC.
If the cable breaks, the plotter does not need to be opened up completely. Only the cable from the adapter to the PC needs to be replaced. The Summa software for cutting and the customer files with the shape to be cut is on the PC.
Sunon ventilators are used for extraction, not for blowing. This is the reason why this ventilator was chosen: the correct suction strength and the fact that the fan is fed at 48V, for which the offer is lower.
Summa has customers world-wide, via distributors. These are companies that cut industrial foil and film, for example, or foil and film for placing advertising on windows or cars.
