(under the class definition) Apparatus comprising the combination of means to shape fluent material (e.g.., molten, plastic, particulate stock, etc..) or means to reshape a "green" preform (e.g.., sheeted dough, etc..) and means to catch or collect an unusable or unused portion of the stock, which portion is not necessary to complete a product made by the shaping or reshaping means or is a reject "green" product.
(1) Note. The gathering must be intentional and not merely inherent catching of undesirable matter associated with
apparatus cleaning means (for which see subclass 225).
(2) Note. A mechanical means (e.g.., doctor blade, screed bar, etc..) spanning a work handler for the purpose of spreading and by its nature causing fluent material to build up behind and thereby maintaining a pool of fluent material behind said means is not considered a gatherer for the purposes of this class.
(3) Note. Sprue of flash are considered excess or rejected stock within the scope of this subclass.
