Abstract
For making a web connection, an adhesive tape is used which essentially features on only one side an adhesive layer. The cover foil of this adhesive layer is comprised of two parts that are separated by a longitudinal seam. Applied on the other side of the substrate of the adhesive layer is at least one narrow adhesive strip, also having a cover foil, which preferably is contained on an edge of the adhesive tape.
Claims15
In combination, a paper roll and a splice for said roll, wherein said splice comprises:
- an adhesive tape having two sides, said adhesive tape having at least one adhesive layer on one of said sides for taping an end of an old web and a leading end of a new paper roll, said adhesive layer being affixed by adhesion to an underside of said leading end, said adhesive tape additionally having an adhesive layer on its other side whereby said other side is adhered to said web or said paper roll at an end of the outermost roll winding wherein said outermost winding is taut, said adhesive tape further having respective longitudinal edges, wherein said adhesive layer on said other side of the adhesive tape comprises at least one double-stick adhesive strip, said adhesive strip having two sides and having an adhesive layer on each of said sides, said adhesive strip being adhered at one of said sides to said other side of said tape, at least one adhesive strip being situated in closely spaced relationship to one of said longitudinal edges and being aligned generally parallel thereto, wherein the adhesion of the adhesive layer on the side of the adhesive strip adhering to said tape is considerably less than the adhesion on the other side of said adhesion strip.
An adhesive tape for making a web connection to a paper roll, comprising:
- a tape member having a front side and a back side, and having respective longitudinal edges, said front side of said tape member including either an adhesive layer or two mutually parallel adhesive layers separated from each other by a narrow space, said adhesive layer or layers supporting a cover foil comprising cover foil members, said cover foil members being separated by a longitudinal seam or by said space;
- and
- at least one adhesive strip having two sides and having an adhesive layer on each of said sides, said adhesive strip being adhered to said back side of said tape member by the adhesive layer of one of said sides of said strip, wherein the adhesion of the side of said adhesive strip adhered to the back side of the tape member is weaker than the adhesion of the other side of said adhesive strip, said adhesive strip extending parallel to said longitudinal edges of said tape member.
An adhesive tape for making a web connection, comprising:
- a tape member having a front side and a back side, and having a respective edge at each longitudinal end thereof, said front side of said tape member including an adhesive layer or two mutually parallel adhesive layers separated from each other by a narrow space, said adhesive layer or layers supporting a cover foil comprising cover foil members, said cover foil members being separated by a longitudinal seam;
- and
- at least one adhesive strip having two sides and having an adhesive film on each of said sides, said adhesive film being fashioned generally dot-shaped or as a series of adhesive areas, said adhesive strip being adhered to said back side of said tape member by the adhesive film on one of said sides, wherein the adhesion of the side of said adhesive strip adhered to the back side of the tape member is weaker than the adhesion of the other side of said adhesive strip, said adhesive strip extending parallel to said longitudinal edges of said tape member.
An adhesive tape comprising:
- a tape member having two sides, one of said sides having a first adhesive layer thereon and the other of said sides having a second adhesive layer thereon, said first adhesive layer being covered by a cover foil subdivided by a longitudinal seam into two parts, said second adhesive layer being disposed stripwise across said other side.
A double-stick adhesive tape, comprising:
- a tape member having a continuous perforation extending generally therethrough as a longitudinal seam in a center area thereof, said tape member having two sides, each side having respective longitudinal edges and having an adhesive layer thereon, wherein the adhesive layer on one of said sides is covered by a cover foil, wherein on at least one side of said perforation the adhesive layer covered by said cover foil is subdivided into two parts by a seamlike separating line, and wherein the adhesive layer on the other of said sides comprises a plurality of adhesive strips disposed generally parallel to said longitudinal edges, one of said adhesive strips being situated in closely spaced relationship to a longitudinal edge, and another of said adhesive strips being situated adjacent said perforation, said strips being situated on a common side of said perforation.
In combination, a paper roll and a splice for said roll, wherein said splice comprises:
- an adhesive tape having two sides, said adhesive tape having an adhesive layer on one of said sides which adhesive layer covers substantially all of said side, said adhesive tape being pierced by perforations which extend longitudinally at the central portion of said tape, said adhesive tape having double-stick adhesive strips adhered to its other side, one of said adhesive strips being situated in closely spaced relationship to a longitudinal edge of said tape and being aligned generally parallel thereto, and another of said strips being aligned in closely spaced relationship to said perforations and generally parallel thereto, each of said adhesive strips being situated on a common side of said perforations, said adhesive tape being folded over at a line defined by said perforations to form a double-stick tape wherein a folded over portion of said back side of said tape also adheres to said adhesive strips, wherein the adhesive force of said adhesive strips to said folded over back side portion is stronger than the adhesive force of said adhesive strips to said other side.
