    Abstract: The invention relates to pressure-sensitive adhesive tapes for flying splice of flat web materials, having at least one splittable carrier and two layers of adhesive, at least one of the adhesives being a silicone PSA, more particularly an electron-beam-crosslinked silicone PSA, and also to a method of producing them. The silicone PSA advantageously has at least one polydiorganosiloxane having the structure —Si(R2)—O—[Si(R2)—O]n—Si(R2)—, where the 2n+4 substituents R independently of one another are monovalent hydrocarbon radicals and n is an integer, and also at least one resin (“MQ resin”) constructed from (R2)3SiO1/2— units (“M units”) and SiO4/2 units (“Q units”), the substituents R2 of the M units being independently of one another alkyl groups, alkenyl groups, alkylsilyl groups, hydroxyl groups or hydrogen.
