Butt-Joint Splice
The butt-joint splice consists of two symmetrically
matched paper tape ends, butted together and held
in position by a bonding agent and an overlay
material. The overlay material can be plastic or paper,
and can be placed on one or both sides of the tape.

With some splicing equipment, the overlay ma-
terial is heat sensitive and is bonded to the tape
through the use of a heated iron. Alignment accuracy
of the tapes is not required of the tape splicing oper-
ator. Tape splicing rate is approximately one per
minute.
With other butt-joint splicing equipment, the paper
is bonded to the overlay material by an adhesive on
the overlay material. Alignment accuracy of the tapes
depends upon the skill of the splice equipment oper-
ator. Tape splicing rate is approximately one per
minute.
ADVANTAGES OF BUTT-JOINT SPLICE
1. The splice can be made in a data-portion of
tape without losing or altering data.
2. This type of splice permits tape repairing due
to tears or damage .
3. A thinner splice - the total thickness of the
tape and splice (with a plastic overlay) is
usually thinner than two thicknesses of paper
tape.
DISADVANTAGES OF BUTT-JOINT SPLICE
1. The quality and accuracy of each splice may
depend upon the skill of the splice equipment
operator .
2. There is a limited variety of accurate butt-
joint splicing equipment.
