DEFINITION

Classification: 19/266

(under subclass 258) Method or means including a step of, or means for, continually urging a roll of a roll pair into engagement with the other roll of the pair to effect a working cooperation. [figure]

(1) Note. Pressure applying device - Figure 5 denotes a specimen of a typical pressure applying device as used in the textile art. In Figure 5, above, "A" denotes a saddle; "B" denotes a stirrup; "C" denotes pressure rolls; "D" denotes a pivoted fulcrumed lever; "E" denotes a pressure applying attachment means; "F" denotes a roll stand, the pressure is transmitted to the pressure roll "C" through the pivoted fulcrumed lever "D", which is pivoted to a fixed center, and in turn through the stirrup "B" through the saddle "A".
