What is drum ratio?
Drum ratio is defined as the number of times the large drum rotates for one rotation of the small drum. The higher the ratio, the faster the pins on large drum whip past the teeth on the small drum. So what does this really mean? In general, the higher the drum ratio, the better the blending. But this does have practical limitations. For instance consider a 25:1 ratio. You are going to crank that large drum 25 times before the small drum goes around once. Think about how your shoulder is going to feel! Testing various ratios on the Strauch machines has shown that a 5:1 ratio is a good balance between physical cranking and blending quality. Our Finest series has a 5:1 ratio. The 200 series and Petite are 4:1. The large drum of the Finest is spinning 20% faster past the small drum compared to the other two carders. So why do we have this difference? In a word…cost. The finest is our top of the line drum carder and we wanted to maximize all the features and benefits associated with the
