Apparatus is provided for packaging compressible material, such as building insulation, in strip form. The compressible strip is wound into a roll and held under compression during rolling to form a compact package. The apparatus includes a main endless belt carried on a frame and positioned and driven in a manner to form a loop in itself which is in the path of the compressible strip being lineally moved toward the belt. The belt is driven to roll the strip on itself as it is moved into the loop, and means are provided for maintaining the belt under tension to place the strip in compression during rolling. When the roll is completed, part of a sub-frame for the belt is moved away from a main frame to cause the loop to open and automatically eject the compressed, packaged roll. A plurality of supporting belts is positioned under a portion of the loop and serves to aid in supporting the loop and the roll as it is being formed and also to provide the drive for the main belt. The supporting belts are driven so that the portions in contact with the main belt loop are in tension and preferably are timing belts. The belts are also at a steeper angle to the horizontal than heretofore. |
