a supply roll of durable plastic wrapping material for use with a wrapping mechanism for wrapping cylindrical cotton modules formed in a module - forming chamber of a cotton harvester is made in lengths connected in end - to - end relationship with velcro ® hook and loop connections provided at opposite ends of each length and having sufficient holding strength for the leading length to remain connected to the following length during the wrapping process , but for permitting the leading length to separate from the following length when the supply roll is subjected to a braking force . other velcro ® hook and loop connections are provided on the lengths of material for securing them about the module with their placement being such to permit modules from 5 ′ to 7 . 5 ′ in diameter to be wrapped using no more than two wraps of material . the lengths of wrapping material may be mechanically stripped from the modules at the gin and cleaned and mechanically reattached in end - to - end relationship and formed into rolls for reuse .
