Abstract
A handtool (1,2) for threading e.g. a weft yarn in a pneumatic weaving machine has a conduit (8,9) issuing therefrom, the free end of which constituting a blowing nozzle (9). Adjacent to the nozzle aperture a guiding surface (3) for the yarn is provided. This tool may be used in difficultly accessible points of the yarn path through the machine. The yarn is presented to the guiding surface (3) of the tool whereafter it is carried along by the air jet of the blowing nozzle (9). In one embodiment the tool has a thread guiding eye (4) with a lateral release slot (5).
Claims6
Handtool for threading a yarn into a difficult-to-reach path in a yarn processing apparatus, comprising a handle, a conduit which has an inlet for connection to a source of pressurized fluid and which extends from said handle and has a discharge orifice adjacent to its free end, a yarn support arranged to hold the leading end of the yarn in position to be entrained by a jet of fluid discharged from said orifice, and a valve for shutting off the flow of pressurized fluid through said conduit, whereby said conduit serves as a probe for placing the leading end of the yarn in position to be inserted into said path by a jet of fluid discharged through said orifice.
