A double surfaced adhesive tape comprising an elongated strip (14) of flexible material having a longitudinally extending center portion (20) and longitudinally extending first and second edge portions (22, 24). The center portion is thicker than either edge portion, and each edge portion has one adhesively surfaced side (26, 28) and one side (27, 29) that is not surfaced with adhesive. The adhesively surfaced sides may comprise adhesives having different tack properties from one another. The adhesively surfaced sides of the edge portions face in opposite directions from one another. The double surfaced adhesive tape is made by mounting first and second rolls (66, 68) of tape adhesively surfaced on only one side on respective first and second rollers (52, 54), and winding first and second tape strips (70, 72) from the respective rolls onto a rotating core (74) such that the strips are joined together with their adhesively surfaced sides facing one another and overlapping along a portion of their respective widths. |
