Infeed guide and roll-on belt for bottle labeling machine

摘要

Apparatus for applying labels to round glass containers by guiding the containers in succession to the surface of a rotating vacuum drum that supports the labels on its surface. The containers are carefully guided by a pair of vertically spaced starwheels and opposed guides with one starwheel and guide holding the body of the container while the other starwheel and guide holding the neck so that the side of the container that first engages the adhesive carrying leading edge of the label will be precisely vertical. The container and label are rolled by the drum along a primary backup pad and then engaged by a vertical, horizontally moving belt so as to roll along a secondary rollon pad. This assures a completely formed wrap-around label with an overlap seam that is consistently formed. The belt is guided at the end adjacent drum over a relatively small diameter of vertically stacked rollers on a vertical axle to provide smooth transition from the drum to the belt while the container is moved from the primary to the secondary rollon pads.
