Paper Strip Movement - How it works
This hand cranked movement work from perforated paper strips. It has been specifically designed for you to custom make your own tunes by marking & punching the paper yourself.
The movement works via a small wheel for each note, known as a star wheel, which enters the hole in the paper, rotating it as the paper passes through, which then plucks the movement comb (the part that makes the sound). We have recently introduced this new improved 30 note version which has a semi chromatic scale with the following notes : C, D, G, A, B, C1, D1, E1, F1, F#1, G1, G#1, A1, A#1, B1, C2, C#2, D2, D#2, E2, F2, F#2, G2, G#2, A2, A#2, B2, C3, D3, E3. The numbers indicate the octave - For example C2 is one octave higher than C1.
Each paper strip lasts about 30 seconds, but depends on how fast you crank the handle. Paper can be joined together with thin tape to make longer tunes. It's best to join using a 45 degree cut on the paper, so the joint gradually goes through the rollers rather than all at once. Never overlap the joints, the thickness must stay as per a single strip, so only butt together and use thin tape.
The movement doesn't have to be fitted in a box to work, but you will need to hold it on a hard flat surface whilst you turn the handle to amplify the sound.
It can be easily fitted into a box and the handle is removeable if you need to fit in an enclosed box with the handle sticking through a hole on the outside.
Approx Size : 13 x 7 x 2.9cm (5 1/8" x 2 3/4" x 1 1/8") excluding handle. Thehandle is removeable & protrudes approximately 3.2cm (1 1/4") from the movement when fitted.
