(under the class definition) Device including at least one member (hereafter referred to, in the definition of the indented subclasses as girt) having an axis extending
laterally* of the material to be moved, in which device as disclosed, (1) a plurality of such members receive and support a loop of indeterminate length* material, the material depending downwardly from supporting contact with one such member and then upwardly to supporting contact with another such member, (2) means are provided to give translatory movement to said member(s) in a direction simultaneously perpendicular to said axis and broadside to said loop, and (3) the material has substantially no movement relative to said member(s) during such translatory movement.
(1) Note. The terms bar, stick, rod, etc., are synonymous with the term "girt" in this art.
(2) Note. In usual operation, a portion of the material at a loading end of the festooner is draped or held relatively stationary over a girt, a succeeding portion of that material is advanced longitudinally, (generally in a vertical direction) until a quantity of material is looped between the girt and the loading (or infeed) means, a portion of that material is draped over a succeeding girt while all or some of the girts move bodily in a direction perpendicular to the axis of the girts and broadside to the loop thus formed (generally in a horizontal direction) and the material is removed from the individual girts as the girts advance.
(3) Note. To be placed in this group of subclasses a patent must claim the device in such terms that it is clear, or it can reasonably be inferred, that a definite loop is found between girts. Devices not clearly within this group may be found in subclass 170, endless conveyors.
(4) Note. The mere naming of a device as a "festooner" or equivalent phrase does not warrant placement of a patent with such a recitation in this group. The significant characteristic herein is the translatory movement of the girts broadside to the loops. Other devices, sometimes named as festooning machines, but in which the material moves in a sinuous path over and under rotated or rotatable rolls. [figure] [figure] [figure]
