Abstract
Abstract In the method of making a hollow plastic articles wherein a label is positioned in each of a plurality of spaced partible molds in a predetermined array, a preform is positioned in each set of partible molds and the molds are closed and the preform is blown outwardly to the confines of the mold to apply the label to the resultant hollow plastic article, the method and apparatus which comprises providing labels on a roll of labels, successively engaging the free end of the web of the roll of labels by a first endless vacuum conveyor, tensioning the portion of the web between a point upstream and the free end by the first endless vacuum conveyor, successively cutting a label on the free end from the remaining tensioned portion, transferring each label successively by moving the first endless conveyor adjacent a second endless vacuum conveyor which is transverse to the the first conveyor, indexing the second endless conveyor to provide an array of labels on the second endless conveyor which corresponds in spacing to the spacing of the array of molds, engaging the array of labels and moving them from a first position adjacent said second conveyor to a second position within the partible molds and depositing the labels in the molds.
