Abstract
A hand-held pneumatic yarn splicing device has a splicing chamber into which a pair of yarn ends to be spliced together may be placed, the chamber having at least one air inlet extending into the chamber for directing air from a high pressure source external of the device into the chamber. The chamber is interchangeable with other chambers and has a pair of projections extending from the wall of the chamber to break up the twist of highly twisted and heat set yarns which are to be spliced together by the action of the high pressure air. The chamber is cylindrical and has a center axial bore and the projections extend radially from the inner wall of the chamber.
Claims15
A yarn splicer for splicing two ends of yarn together comprising:
- a body having an opening and a passageway for receiving high pressure fluid, a removable barrel located within the opening, said removable barrel being substantially cylindrical and having a yarn chamber having a splicing bore extending therein communicating with said passageway such that when fluid flows through said passageway it enters said bore, said bore being defined by an interior wall of said chamber, said chamber having a slot communicating said bore with the exterior of said body for receipt of said yarn into said bore, and at least one projection extending substantially radially from said wall into said bore.
A yarn splicer for splicing two ends of yarn together comprising:
- a yarn splicing chamber having a longitudinal axis extending between first and second ends of said chamber, means for directing pressurized air into said chamber at an angle inclined relative to said axis, said chamber having a slot substantially parallel to said axis for receipt of a pair of substantially parallel yarns therethrough and into said chamber, said chamber including an interior wall, and at least one projection extending from said wall partly into said chamber in a cantilevered manner and having a free end for effecting a change in air flow pattern of said air in said chamber.
