Apparatus and process for in-mold labeling

摘要

A process for use in an in-mold labeling application utilizes a rolled label sheet having a multiplicity of pre-printed non-adhesive labels and a pre-printed registration mark associated with each of the labels, the process detecting each of the registration marks to align the label sheet in a predetermined longitudinal position before labels are cut therefrom, conveying the rolled label sheet forward or backward, cutting one or more labels from the label sheet, forming a controlled loop in the label sheet, detecting each of the registration marks for aligning the label sheet in a position of registration, providing a hold down vacuum for maintaining the label sheet in a position of registration during conveyance to a predetermined label removal position, and releasing the hold down vacuum to permit removal, by an external pick and place device, of one or more of the previously-cut labels.
