DEFINITION

Classification: 226/27

(under subclass 24) Device wherein the regulating means acts to longitudinally* align a particular point on the material with respect to a particular point in space at a particular instant of time.

(1) Note. For further elaboration of the term "registration", see (1) Note to subclass 2.

(2) Note. In this subclass 27 are found patents for devices which overfeed and retract.

(3) Note. Some patents may disclose, but not claim, that an operating machine is changed in response to the signal produced by the detection means.

(4) Note. To register material, means must be provided to indicate the relative position of a reference point, hence, devices herein must disclose two "sensing" means, although the means to indicate the relative position of the reference point may be only a particular part of a machine which controls the material-detection means.
