Indeed, rotating arms that are handling the plastic film roll are embedding servomotors with a lot of sensors (optical, proximity, etc.) that allow accurate and smooth film wrapping operations. All those rotating components are connected to the control unit that is integrated into the fixed part of the machine. Slip rings are then mandatory to enable continuous 360° rotation making the pallet wrapping possible.
Most of the time, OEMs can find a match to their needs among our wide range of capsule or thru-bore standard solutions. PES S.A. can provide this way a competitive and quickly available slip ring that will help our customers to transfer motor power and feedback along with sensors signals from their controller to the rotating arm. Our rotary joint solutions can cover a wide range of electrical or even fluidic applications, custom designs can always be analyzed in some very specific cases or to allow better integration in your structure, so do not hesitate to reach out to us for some advice.
