ABSTRACT:
The machine is disclosed for banding skeins or balls of bunched or wound material such as wool thread. The machine includes a banding apparatus comprised of a plurality of individual banding units connected in a closed loop chain. Each banding unit includes a closed loop endless belt driven by guide rollers. A pocket for receiving the skein or ball of material is formed by a portion of the endless belt. An entrance to the pocket is opened and closed by use of a movable guide roller. The skein or ball to be wrapped is placed into the pocket. A printed band is also placed into the pocket between the skein or ball and an edge wall of the pocket. The pocket is then closed as the belt is rotating. One end of the band has glue thereon so that as the pocket rolls the skein or ball and band, the band is wrapped around so that opposite ends of the band are glued to one another. The banding unit then continues around the closed loop as the glue dries. Finally, the pocket opens and the banded skein or ball drops free onto an outlet conveyor. Preferably the band is printed with indicia such as a dye number or lot number and is then fed in synchronized fashion to one of the banding units shortly after the banding unit receives the skein or ball of material from an input conveyor. The input conveyor, the printer, and the banding apparatus are all synchronized with one another.
