Das Band

Das Band is a multicolored LD-PE ribbon. It is flexible but durable, has a nice smooth surface and can be cut into pieces easily. This assures high adaptability in many thousand applications. It was manufactured within two weeks in line with the Big Banana factory.

Dimensions: 1,5mm x 15mm x ~250.000mm 

Material: Riblene® MV10

Processing

The Extruder is the machine creating das Band. It works similar to those machines known from industrial production of plastic pipes, sheets and profiles. A turning screw (here: ordinary 20mm drill bit) takes plastic pellets from a feed hopper and squeeze them through a die. While in industrial machines the energy is provided by shear strain and high pressure, this machine works with an heating area where the pellets starts to melt. After inserting energy into the material, it needs to be cooled down after leaving the die immediately to bring it into shape. (This loss of energy is a general problem during the extrusion process, even in industrial processing.) Several rotating rolls work as a shaping unit.
