DEFINITION

Classification: 239/673

(under subclass 672) Apparatus comprising at least two strewing means, each of which rotates about an axis to perform its strewing function and each of which is disclosed as strewing material into final position in the ambient, rather than to another downstream strewing means, the material being presented to each of the strewing means in a direction which is substantially parallel to the axis of rotation and being scattered in substantially a radial direction.

(1) Note. For the meaning of "rotates about an axis" see (1) Note in subclass 681.

(2) Note. Just what constitutes a plurality of strewing units rather than a single unit with a plurality of parts is sometimes difficult to decide. If one unit rotates on a different axis than another, or in a direction opposite to that of another, a plurality of units is considered to exist. However, sometimes where there are distinct sub-assemblies, each comprising a complete unit, a plurality of units are considered to exist even if they rotate about the same axis.
