When you pick up your custard cream or bourbon biscuit, you probably don't think too much about how it's made. It tends to go straight in your mouth - or sometimes via a cup of tea. Although you would certainly take notice if there was too much or too little filling between the two biscuits. Getting the right amount isn't easy, especially when the consistency of the filling is constantly changing with temperature, humidity and other ingredient factors in the manufacturing process. With our Speed Modulation Gearboxes, however, biscuit producers throughout the world can be confident that the same amount of filling is applied regardless of the line speed or any other factor.
