Abstract
Abstract A hand-held battery-powered apparatus for splicing thermoplastic yarn embodies a pistol-shaped body having a primary guide rail thereon and a fixed heating element near one of this rail. A trigger operated carriage moves on the rail and carries coacting jaw means which grip and move the yarn into close proximity with the radiant heating element. The heating element is energized automatically by the closing of a switch when the carriage is retracted.
