Abstract: This relates to the mounting of a label magazine in a manner wherein labels carried by such label magazine may be rotated or slewed about a line extending axially of the label magazine through the center of a label. The slew control device is used to effect such rotation and thus orientation of a label so as properly to position the label for transfer. In the preferred usage of the slew control device, each label is transferred into a blow mold half and proper orientation of a label with respect to a blow mold half cavity is obtained utilizing the slew control device. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
