Abstract
A label tape having self-adhesive labels sticking on a carrier strip, with said labels being separated from each other by cuts running mainly transverse to the longitudinal axis of the label tape and being subdivided each into sections by at least two cutting lines in form of periodic curves running in longitudinal direction to the label tape. The height of the labels is greater than and aliquant to the periodic length of the cutting lines, the form of the cutting lines is chosen such that parts of the cutting lines confine an angle of not more than 90.degree. and the curves of the cutting lines of the label tape are staggered in a longitudinal direction. The height of the label measured in longitudinal direction of the label tape differs from the periodic length of the cutting lines and of a morefold thereof, and the periodic length of the cutting lines is lower than the height of a label. Thus, security against forgery by the invention is improved.
