ABSTRACT:
A straight line transport, positively controlled banding apparatus and method. According to the method of the present invention, transport of a band is in a straight line from a starting position adjacent a mandrel, onto the mandrel band receiving end, along the mandrel to the mandrel delivery end, and directly off of the mandrel onto an article to be banded, and is positively controlled throughout the entire transport step of the process. According to a preferred embodiment of the banding apparatus, the apparatus comprises a tube opener, drive rollers for feeding and creasing a tube of banding material, a mandrel having a receiving end tapered to a knife-like edge, fingers for transporting a band along the mandrel, and means operable in synchronism with the fingers for holding the mandrel. In operation, the tube opener is inserted into the end of a tube and the tube end fed through the drive rollers which results in a partially open tube creased at ninety degree intervals around the tube. The creased tube is fed onto the receiving end of the mandrel which fully re-opens the tube. The knife cuts the tube above the mandrel to provide a band which is partially on the mandrel. The mandrel is lowered and the fingers moved initially in towards the mandrel above the band and then downwardly along the mandrel to strip the band from the mandrel onto an article positioned below the mandrel.
