ABSTRACT:
A process for wrapping a rotating bale of mineral fiber strip in the form of a felt-roll with an outer closed-face backing strip with protective wrapping applied as part of the winding process for packaging which entails bringing the protective wrapping, having a coating of adhesive material at the back end thereof into the circumferential area of the rotating bale with the front end thereof, with a length exceeding the circumference of the bale and being frictionally connected to the bale; and turning the bale and pressing the back end of the protective wrapping onto the outside of the winding of the protective wrapping, therebelow, to attain a lasting bonding, wherein the frictional sticking connection between the front end of the protective wrapping and the bale is produced exclusively by an adhesive effect, between the inner surface facing the bale and the bare outer surface of the backing strip, and the front end of the protective wrapping is placed on the bale at a distance from the outside end of the last winding of the felt roll, and wherein the length of the protective wrapping exceeds the circumference of the enclosed bale substantially only by the circumferential width of the bonding zone between the back end of the protective wrapping and the outside of the winding of the protective wrapping lying thereunder.
