A method of making a shrink sleeve in which the inner surface of the shrink sleeve is provided in a hot melt adhesive and a cross-linking substance which, when heat is provided the shrink sleeve onto a cable, causes cross linking of the hot melt adhesive to reduce its flowability.

[ I claim:] [1.] A method of making a shrink sleeve of a thermoplastic synthetic resin for cable connections and branches, comprising the steps of:forming a layer of a thermoplastic synthetic resin shrinkable at a high temperature, thereby providing a shrinkable sleeve for sealing cable connections

[ I claim:] [1.] A method of making a shrink sleeve of a thermoplastic synthetic resin for cable connections and branches, comprising the steps of:forming a layer of a thermoplastic synthetic resin shrinkable at a high temperature, thereby providing a shrinkable sleeve for sealing cable connections and branches; andforming an adhesive layer on an entire internal surface of said sleeve by:lining a layer of a cross-linkable hot melt adhesive over said entire internal surface of the sleeve,thereafter providing a layer of a perforated carrier synthetic resin containing a cross linker over said layer of said hot melt adhesive, andpressing said layer of the carrier resin into the layer of said hot melt adhesive at a low temperature lower than said high temperature, thereby providing a flow of the hot adhesive into said layer of the synthetic resin and arresting said flow upon heating the sleeve at said high temperature by cross linking of the layer of hot adhesive by said layer of the carrier synthetic resin.
