On its versions DSR RL, ULTRASLIT® OHP and ROBOSLIT®, SP ULTRAFLEX provides as standard electro- mechanical floor lifting unwind arms which move down vertically to lift the new unwind reel off the floor. The vertical movement of this unit affords a better positioning convenience that the pivoted motion of most contemporary floor lifting mechanisms. The use of a motor for this activity also makes the machine free from hydraulics, thus ensuring compliance with the food and drug safety standards specified for secondary packaging.
