A pneumatic weaving machine includes an air fed weft inserting main blowing nozzle cooperating with a device arranged upstream of its inlet and adapted to intermittently interrupt the inserting motion of the weft yarn effected by the nozzle. At least one auxiliary blowing nozzle is arranged in series between the outlet of the main blowing nozzle and the adjacent end of the weaving shed of the machine, there being a free space between the outlet end of the main blowing nozzle and the inlet end of the auxiliary nozzle, through which the air stream from the main blowing nozzle laterally escapes.

Pneumatic weaving machine and weft inserting device for such a machine

A weaving machine of the type in which weft insertion is effected by a fluid flow and in which a plurality of notched blades arranged closely adjacent each other in front of the reed confine a guide passage for the weft threads, said guide passage being laterally open towards the reed and being adapted to move into and out of the shed in synchronism with the reciprocation of the reed, wherein each guide passage forming blade comprises at least two spaced thin blades which are mutually connected at least at the ends at which they enter and leave the weaving shed during the reed movement.

Weaving machine of the type in which weft insertion is effected by a

A loom comprising two sheets of warp threads which are momentarily held in diverging planes to form a weaving shed with a conveying tunnel for wefts, a blowing nozzle arranged in position at one side of such shed to propel wefts through such shed by means of a fluid discharged from said nozzle, and a main tensioning device arranged in position at the other side of such shed, operating with a fluid jet, to tension inserted wefts during the beating up movement of the loom. The jet is so arranged that it issues substantially, transversely, and freely across the conveying tunnel to suck in the weft and is caught by a passage disposed in alignment with said jet. An auxiliary tensioning device is provided and is constructed similarly to the main tensioning device. The auxiliary device is disposed at the side of the main device. The main and auxiliary devices are used for normal and startup operations, respectively, and each has gas or air pressure supply means for normal or startup operation.

Weaving loom

A weft thread inserting nozzle, comprising a hollow needle, having a closed tip at one end and the other end of which is adapted to be connected to a source of pressurized fluid, an outlet opening being provided in the side wall of the needle adjacent the tip, wherein said outlet opening is composed of a plurality of closely adjacent elementary apertures of smaller diameter.
