An apparatus for wrapping fireworks shells is provided and includes a base provided with preferably three support rollers configured to support a spherical firework shell thereon; stepper motors coupled to two of the rollers, a computer coupled to the stepper motors to control the movement of the stepper motors and thereby control the angular rotation of the shell on the rollers, and a dispenser assembly which dispenses continuous-feed tape for wrapping the shell and applies and presses the tape to the shell as the shell is rotated on the rollers. The computer instructs the stepper motors to systematically, at times, rotate the rollers at relatively different speeds, such that a shell on the rollers is subjected to angular rotation and-the tape is evenly applied to all portions of the shell such that the tape forms a very even casing of the firework shell.

Here is a clip from a year ago of us pasting a bunch of 5" & 6" shells with the WASP machine. I believe I had around 30 5" & 20 6" shells that we pasted in just a couple hours. Clip only shows the tape wrapping action--not the "smoothing" action after the tape is on.
The shell in the video is a 6" Purple Heart--one of several specialty shells I made for a show honoring our veterans.
Awesome machine--sure beats doing it by hand!!!

Here is my video from 2009 at the PGI convention.

Its all a dying art as far as I can see. For years this fireworks making group kept everything secret and never seem to want to teach or show anyone anything. I would be shocked if there is still a market in United States for this device.
