Abstract

Referring to Figure 1, a labeling machine 10, includes a vacuum label wheel 11 which is used to transport labels from a label feeding device (not shown) to articles fed to a labeling station (not shown). Typically, label wheel 11 includes a vacuum chamber which periodically communicates with holes on a peripheral portion of the wheel to provide thereon a vacuum pressure. This pressure is used to hold labels being trans-ported by the wheel from the label feeding device to articles at said station. The vacuum chamber of wheel 11 is coupled by a tube 12 to a valve 13, and valve 13 is coupled by a tube 14 to a vacuum pump 15.

AN IMPROVED LABELING MACHINE (Cont'd)

Referring to Figure 1, a labeling machine 10, includes a
vacuum label wheel 11 which is used to transport labels from a
label feeding device (not shown) to articles fed to a labeling
station (not shown). Typically, label wheel 11 includes a
vacuum chamber which periodically communicates with holes on a
peripheral portion of the wheel to provide thereon a vacuum
pressure. This pressure is used to hold labels being trans~-
ported by the wheel from the label feeding device to articles
at said station. The vacuum chamber of wheel 11 is coupled by
a tube 12 to a valve 13, and valve 13 is coupled by a tube 14
to a vacuum pump 15.

Referring to Figure 2, the valve 13 includes a member 20 into
which a cylindrical bore 21 vertically extends. Bore 21 is
coupled by a conical seat 22 to a larger bore 23 vertically
extending below the seat and to bore 23 by a pair of slots 24
and 25 in the seat. Bore 23 has an internally threaded lower
end 25 which supports a threaded member 27 having a projection
28. Projection 28 provides a platform 29 in bore 23 for a
spherically shaped member 30, the diameter of the member being
smaller than the diameter of bore 23. Movement of member 30 is
confined by the conical seat 22,...
