Abstract
A device for the pneumatic splicing of yarns, especially elastane yarns, has a splicing body (25) defining a splicing conduit (26) loadable with compressed air, as well as with pneumatic tubes (33, 34) for pneumatically preparing the yarn ends (31, 32) to be spliced, wherein the central axes of the pneumatic tubes intersect the central longitudinal plane of the splicing conduit. The pneumatic tubes (33, 34) are replaceably fixed in bores (46, 47) of the splicing body (25), with the inlet opening (48, 49) of the pneumatic tubes (33, 34) positioned in the immediate vicinity of one of the two outlets (50, 51) of the splicing conduit (26). The inlet opening (48, 49) of the pneumatic tube (33, 34) has a funnel-shaped contour (52) that promotes insertion of the cut ends of the upper and lower yarns (31, 32) into the pneumatic tubes (33, 34).
