Abstract
A device with a first tape supply roll including a first length of tape helically wound about a first core with its adhesive coating on the side of its backing adjacent the core, a second tape supply roll comprising a second length of tape helically wound about a second core with its adhesive coating on the side of its backing opposite the core, and first and second hubs mounted on a frame for rotation about spaced parallel axes. The first hub is adapted to receive the core of the first tape supply roll and position a first edge of the first length of tape at a first predetermined position axially with respect to the first and second hubs, and the second hubs is adapted to receive the core of the second tape supply roll and position a first edge of the second length of tape at a second predetermined position axially with respect to the first and second hubs with the width of the first length of tape extending from the first position past the second position and the width of the second length of tape extending from the second position past the first position so that portions along the first edges of both lengths of tape are positioned between the first and second positions. Tapes are pulled from the first and second tape supply rolls along paths comprising a common path portion having a beginning position at which the portions along the first edges of both lengths of tape are adhered together to form a composite tape structure with a portion of a layer of adhesive exposed on each of its major sides.
