In-mold labellers for dual cavity mold.

摘要

A labeller (20) for applying simultaneously two labels (L) to a dual cavity mold half (124). The labeller is especially constructed to receive a pair of labels from a pair of adjacent label magazines (M) and then move one of the labels towards the other so as to reduce the overall width of the pair of labels. This permits the pair of labels to be moved between a pair of mold halves (122, 124) within the limited space available and thereafter be rotated for alignment with the dual cavities (126) of the mold half for positioning within the dual cavities. The labeller includes a support member (22) having mounted thereon a pair of carriers (30, 32) for separate movement towards and away from one another. The carriers are moved such that one normally remains fixed after a label is picked up by pick-up heads (96) carried thereby while the other carrier is moved towards the first carrier so as to move the labels together. The labeller is mounted in offset relation away from the mold half which is to receive the labels so that the labels may now be swung into alignment with the cavities of the mold half by pivoting the labeller. After this occurs, both carriers are actuated so as to separate the labels and to align the labels with the mold cavities, after which the labeller is advanced towards the mold cavities to position the labels within the respective mold cavities. <IMAGE>
