The CB-15 is designed to band the joint portions of the cap and body of the filled gelatin capsules.  
 
The banding takes place as the capsules pass over two rollers that are partially immersed in gelatin, which is electrically heated and temperature controlled. The result is a smooth, liquid-tight band, which produces a seamless joined capsule. The banded capsules pass over drying fans as they progress to the pull-off station. The capsules are discharged from the machine by vacuum.
