ABSTRACT:
A splice of abutted ends of sheet material and method of making the same employs a splicing tape formed of an adhesively coated support film which comprises a biaxially oriented, heat-set, coextruded laminate formed from a layer of a crystalline polyester material and a layer of less crystalline polyester material, with the thermosetting adhesive coating the surface of the latter layer. The splicing tape is applied with sufficient heat and pressure to cause intimate contact of the thermosetting adhesive with the abutted ends being spliced.
