Constant coefficient noiseless friction retard member

Constant coefficient noiseless friction retard member

A retard member for use in a friction retard sheet separator and feeder (Fig. 1) has a support member (16), a friction retarding surface layer (17) of an ethylene propylene diene rubber having a relatively stable coefficient of friction and an intermediate vibration absorption layer (18), between th...
