Yarn splicing device

Abstract

A yarn splicing device ( 10 ) for pneumatically joining two yarn ends ( 31, 32 ), with a splicing head ( 19 ) that is fixed on a foundation ( 22 ) and comprises a splicing conduit ( 20 ) with at least one opening ( 34 ) for delivering compressed air. The splicing conduit ( 20 ) comprises at least two additional suction intake openings ( 33 ) that can be loaded with a vacuum and are arranged on both sides of the opening ( 34 ) for delivering compressed air.

What is claimed is:  
     
         1 . A yarn splicing device for pneumatically joining two yarn ends, comprising a splicing head fixed on a foundation and having a splicing conduit with at least one first compressed air opening loadable in a defined manner for delivering compressed air into the splicing head and at least two suction intake openings loadable with a vacuum, the suction intake openings being arranged respectively on opposite sides of the compressed air opening.  
     
     
         2 . The yarn splicing device according to  claim 1 , characterized in that the suction intake openings are arranged symmetrically to the compressed air opening.  
     
     
         3 . The yarn splicing device according to  claim 1 , characterized in that the suction intake openings are connected via a common vacuum line to a vacuum source.  
     
     
         4 . The yarn splicing device according to  claim 3 , further comprising a second independent vacuum source.  
     
     
         5 . The yarn splicing device according to  claim 4 , characterized in that the second independent vacuum source comprises an injector nozzle.  
     
     
         6 . The yarn splicing device according to  claim 1 , characterized in that the suction intake openings empty in a bottom area of the splicing conduit.  
     
     
         7 . The yarn splicing device according to  claim 6 , characterized in that the bottom area of the splicing conduit has an essentially U-shaped cross section.  
     
     
         8 . The yarn splicing device according to  claim 6 , characterized in that the bottom area of the splicing conduit has an essentially V-shaped cross section.
