DEFINITION

Classification: 72/184

BY USE OF "FLYING TOOL" ENGAGING MOVING WORK:

(under the class definition) Subject matter including apparatus, or method employing apparatus, wherein work* moves in its entirety along a predetermined path, both to said apparatus and during deformation by said apparatus, which apparatus comprises a tool face* having two components of movement, one being toward the work into deforming engagement therewith and the other being in the direction of work movement during deformation.

(1) Note. A roller* that rotates about an axis, which axis is fixed relative to a deforming instrumentality or is movable only towards (but not with) the moving work, is not considered to be a flying tool for this and indented subclasses. However, a roller mounted on an axis that moves with and parallel to the work surface during deformation is considered to be a flying tool, and a roller-like-tool* comprising a noncircular surface rotating about an axis is also considered to be a flying tool.

(2) Note. The definition is intended to include a patent disclosing introduction of work into an apparatus along a predetermined compass direction and deformation of such work by a tool-face as the work and tool-face move along the opposite compass direction. Examples of such disclosure are found in subclass 189. The definition is not intended to include a patent disclosing introduction of work into an apparatus along a first direction and deformation by a tool as the work and tool move along a direction substantially at right angles to the first direction. Examples of such disclosure are found in subclasses 343+.
