A harness frame for looms includes a pair of parallel spaced vertical side plates, and a pair of heddle-support bars extending perpendicularly from the vertical side plates. Each of the vertical side plates has an intermediate portion which, in horizontal cross section, extends at right angles to the general plane of the harness frame.

Harness frame for looms

A harness frame for looms includes a pair of parallel spaced vertical planar side plates, and a pair of heddle-support bars extending perpendicularly from the vertical side plates. Each of the vertical side plates has an intermediate portion which, in horizontal cross section, extends at right angles to the general plane of the harness frame.

A weft tensioning device in a shuttleless loom includes a weft yarn feeder and a tension compensator interposed between the weft yarn feeder and a filling carrier. The tension compensator has a pair of weft guides and means disposed between the weft guides for intermittently shifting the weft yarn sideways off a path between the weft guides in response to reciprocation of the filling carrier. The weft yarn feeder has weft yarn winding means, the diameter of which is variable to meet different yarn demands for various widths of narrow fabric to be produced or to compensate for varying yarn stretchability due to different degrees of ambient temperature and humidity.

Weft tensioning device

An apparatus for manufacturing a slide fastener stringer including a woven stringer tape and a coiled fastener element woven into the tape along a longitudinal edge thereof. The apparatus comprises a plurality of harnesses for forming a shed of warp threads, a filling carrier for inserting a weft thread through the warp shed, a first reed for beating the weft thread in the shed against the fell of the tape, means for forming the coiled fastener element to be woven into the tape by the weft thread, and a second reed for beating successive coupling heads of the coiled fastener element one after another against a point which is in alignment with the fell of the tape. The second reed is operatively connected to the first reed so as to synchronize the beating action of the second reed with that of the first reed.

Apparatus for manufacturing a woven slide fastener stringer

An apparatus for manufacturing a woven slide fastener comprises means for weaving a slide fastener stringer tape, a mandrel around which a monofilament is coiled as it is woven into the stringer tape, and a coiling rotor assembly having a pair of wheels rotatably mounted in a pair of housings and on a floating axle to which the mandrel is fixed, and having guide means rotatable for revolving the monofilament in an orbital path around the axle. A pair of plungers jointly or individually act between the floating axle and one of the housings along a path diametrically across said orbital path by which the axle is held immovably with respect to said one of the housings. The plungers are retractable one at a time out of the orbital path so as to allow the monofilament and the guide means to cross the path of movement of the plungers.

Apparatus for manufacturing a slide fastener stringer having a woven

A shuttle for ribbon looms comprises a housing and a bobbin rotatably supported in the housing for carrying a weft thread to be wound therearound. A tensioning device is provided in the housing for keeping the thread under constant tension while being unwound from the bobbin and running, the tensioning device including a frictionally rotatable roller around which the thread is wound, and means for adjusting the tension of the thread. A thread discharge eyelet is supported on the housing for discharging the thread therethrough out of the housing, the eyelet being located at the bottom of the housing and adjacent to the latter. The thread is directed from the bobbin through the tensioning device to the discharge eyelet.
