Apparatus for applying labels in the molds of a plastic blow molding machine

In an apparatus for making hollow plastic articles wherein a label is positioned in each of a plurality of spaced particle molds in a predetermined array, a preform is positioned in each set of particle molds and the molds are closed and the preforms blown outwardly to the confines of the mold to apply the label to the resultant hollow plastic article, wherein the improvement comprising an apparatus for delivery of the labels which comprises

• means for moving a web label material past a die punch station,
• a die punch at said die punch station,
• vacuum devices,
• means for positioning said vacuum devices,
• said means for positioning said vacuum devices being operable to position said vacuum devices in a position such that labels can be punched successively from said web and delivered directly to the stationary vacuum devices, and
• said positioning means including means for controlling the movement of said vacuum devices in a continuous manner and said vacuum devices are momentarily stationary adjacent said die punch station and are momentarily stationary adjacent a position spaced from said die punch station,
• said positioning means being operable to hold the vacuum devices such as to maintain the plane of a label in substantially the same plane at the die punch station and at the position spaced from said die punch station.
