摘要： A SUPPORT FRAME FOR THE YARN SPLICING APPARATUS IS PORTABLE AND ADAPTED TO BE SUSPENDED DIRECTLY ON THE RACK WHICH SUPPORTS THE BEAMS OF YARN WHOSE YARN ENDS ARE BEING FED INTO A CARPET TUFTING MACHINE. THE APPARATUS FRAME MAY BE ATTACHED TO THE BEAM RACK AT THE LOCATION OF A SPENT BEAM WHICH IS BE REMOVED FROM THE RACK AND REPLACED BY A FULL BEAM. THE SPLICING APPARATUS HAS MEANS FOR ALIGNING AND SECURING THE YARN ENDS TRAILING FROM THE CARPET WITH A LIKE NUMBER OF YARN ENDS ON A FULL BEAM AND A RADIANT HEAT SPLICING CARRIAGE IS PROPELLED ACROSS A GUIDE TRACK IN CLOSE PROXIMITY TO THE ENDS TO BE FUSED OR SPLICED.

摘要： 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.
