Find the Proper Slip Ring Solution to Enhance the Performances of Your Automated Wrapping Machines

Automated wrapping machines thanks to slip rings

The global economic context with the rise of e-commerce has put a lot of pressure on logistics companies in those last years. Fortunately, automated wrapping machines can help to save time and get rid of the heavy physical task that is wrapping the pallet with plastic film. Today, those machines are increasingly popular and OEMs continuously innovate, bringing more and more technology to enhance the quality and performances of their machines.

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 ring 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.
