Servo – Wrapping Machines
Wrapping Machines
Wrapping machines in the packaging industry are often placed at the end of manufacturing lines in order to wrap products in plastic film material for shipment. The application highlighted here provides a high-end servo solution for cutting plastic material with a flying shear operation so that products can continually move forward. A second indexing servo axis assists in spacing the products at equal distances on the main conveyor. A large number of wrapping solutions can also be done through combining a series of indexing movements.
Example Applications
Wrapping applications in the packaging industry can be used to package a wide range of different products. Example applications include:
♦ Bottle & Case Wrapping
♦ Box Wrapping
♦ Tray Overwrapping
♦ Shrink Wrapping
