Print Wheel

A typewheel requires readily flexible fingers and durable type elements able to withstand repeated print hammer impacts. These objectives can be achieved by using two different polymeric materials.

In the figures, the typewheel fingers 1 are made of glass filled nylon and the type elements 2, molded thereon, are of alpha-cellulose-filled melamine (or urea) formaldehyde. This particular combination of materials provides a light-weight typewheel with minimum rotary inertia.
