(under the class definition) Apparatus having means associated therewith for performing some function in addition to or in perfecting the basic encirclement or encasement of the contents in its cover and not provided for in the preceding subclasses.
(1) Note. The combination of mechanism to feed the cover, cover web or blank including severing means therefor, mechanism to feed the contents, mechanism to apply an adhesive to the cover, mechanism to cause the cover to be placed around or about the contents, or to place the contents within the cover and close the same, and mechanism to discharge the completed package from the machine, which mechanism may have incorporated therewith a stacking or piling device where no further packaging is involved, has not been considered as including means or features perfecting the basic encirclement or encasement of the contents in its cover.
(2) Note. In this subclass have been placed patents which claim packaging machines within the scope of this class and add an additional feature thereto such as a vacuum cleaner to pick up severed edges of a tea bag; a chute to catch dust and convey same clear of the machine; a portable conveyor to gain access to an improperly wrapped article; a brush to cause an incompletely filled package to leave a vacancy; brushes for cleaning spilled granular contents from the machine bed; a tray to catch crumbs during a bread wrapping operation; a device to remove surplus ice cream; a device which imprints web contents, forms a carbon copy, folds contents into separate covers and stores the copies; a device to smooth the cover after the package is formed; a device to remove a rubber band from contents parts and to place a cover over said parts; and machines which alternately form a carton (a Class 93 operation) or close the flap or flaps of a filled carton; and machines which test or inspect.
