Definition statement

This subclass covers:

Apparatus or methods for weighing whereby balancing is effected by fluid action, magnetic means, electrostatic means or the like, e.g.:

Conveyer-belt weighers.

Apparatus or methods for automatic feed or discharge for weighing-out batches of material, or for check-weighing of material dispensed into removable containers.

Apparatus or methods for weighing material of special form or property.

Weighing apparatus or methods adapted for special purposes, e.g.

Details or accessories of the weighing apparatus described.

Relationship between large subject matter areas

Measuring of forces is classified in groups G01L 1/00 and G01L 5/00. The borderline between subclass G01Gand subclass G01Lshould be determined based on whether the features relevant for classification are focussed on the force sensor or on the weighing device.

Packaging articles is classified in subclass B65B whereas apparatus for conveying articles are classified in subclass B65G The borderline between subclass G01Gand subclasses B65BB65Gshould be determined on whether the features relevant for classification are focused on packaging/conveying or on weighing.
