DEFINITION

Classification: 414/788.1

Stack forming apparatus:

(under subclass 788) Apparatus which constructs a stack* by placing one article above or below another in contacting relationship.

(1) Note. Apparatus which first places articles into a horizontally extending series and then tilts the series as a unit to form a vertically extending stack* or tier* is considered proper for this and the indented subclasses, since the articles are placed into an assemblage and do intersupport each other for a portion of the time they are together. The mere tilting of an article series into a stack* is not considered proper for this area and is found in 414-754+, since the assemblage is only reoriented and not constructed.
