Devices not otherwise classifiable for directing the material to be wound to the reel drum or bobbin or miscellaneous guides for winding machines, excepting guides and guards for fabrics or webs and spool-holders.
(.5) Note. Where the device or guide is claimed with no significant guide structure but merely in terms of the composition or material of which it is composed, it will be classified in the appropriate composition or material class even though there is no claim to the composition, per se. In this connection the following classes should be considered: (a) Class 75, Specialized Metallurgical Processes, Compositions for use Therein, Consolidated Metal Powder Compositions, and Loose Metal Particulate Mixtures, for articles defined solely by their metal or alloy composition; (b) Class 106, Compositions: Coating or Plastic. Note particularly the class definition for the type of composition within the scope of Class 106 and for compositions elsewhere classified; (c) Class 428, Stock Material or Miscellaneous Articles, subclasses 544+ for stock materials, e.g., of indefinite length, which are all metal or have adjacent metal components; and (d) Class 520, Synthetic Resins or Natural Rubbers, appropriate subclasses for synthetic resins or natural rubber and compositions thereof.
