  • Patent number: 5062251
    Abstract: A process and apparatus for application of a carrying grip or handle by means of adhesive tape to a row of continuously moving cartons during automatic packing and sealing operations, wherein each case a predetermined length of adhesive tape is applied automatically to each carton, whereby between the attachment of the two ends of the predetermined length of adhesive tape on the carton, the adhesive tape is acted upon by a movement which is different with respect to at least one parameter from the movement of the carton, thus forming the excess length which constitutes the handle. The adhesive side of the excess length of adhesive tape has been previously covered or masked automatically with a cover tape in an operational step which is synchronized with the application of the adhesive tape to the carton (FIG. 4).
