Date Oct. 6, 1988.A masking tape (10), for example for spray-painting, comprises a strip (11) of tearable material such as paper having an upper face, a lower face; a first pressure-sensitive adhesive layer (12) covering said lower face of said strip from one side edge thereof to the opposite side edge; a second pressure sensitive layer (13) applied to said upper face of said strip, said second layer having a longitudinal extent co-extensive with that of said strip and a transverse extent less than half that of said strip and being positioned close to one edge (11B) of said strip; and a release liner (14) covering said second adhesive layer. The masking tape is to be fixed to a surface to be painted in such a position that the free-edge (11A) of said strip forms a border to the area to be painted. The release liner is removed and a masking paper is fixed to said adhesive layer and cut clean along the inner edge thereof. The masking tape is manufactured according to the invention by laminating two tapes, one wider tape comprising a tearable strip with an adhesive layer on its lower face, and a narrower tape comprising a release liner and a releasable adhesive layer covering the lower face of the release liner and being securely attached to the upper face of the wider tape. |
