Ramp Crock (Hand Operated) provides a reciprocating rubbing motion simulating the action of a human finger and forearm. It is used for determination of fastness of dyed and printed textiles to dry and wet rubbing.
The Ramp Crock (Hand Operated) is so designed that the 16mm diameter finger moves back and forth, with each complete turn of the crank, in a straight line along a 104 ± 3mm track on the specification, with a downward force of 9N.
