In order to ensure an extended preservation term to a feeding product for animals, such as hay, straw and fodder, after harvest the product is compressed to form a cylindrically shaped body or object and then helically wrapped up with a web-like film of plastics material. To this end, the body or object is brought to bear on a series of drive rollers imparting thereto a rotary motion about its own axis, while from a reel or roll which is provided with a continuous rotary motion about said body or object the web like film is unwound. The cross-wrapping of the heap is advantageously completed by a peripheral supplementary wrapping of the heap.
