Abstract: A side stay for a heddle frame is disclosed. The heddle frame has a hollow metal frame member which is filled with a plastic material and has an opening in one wall thereof. A supporting element extends from the plastic material through the opening in the metal frame and is insertable within a hollow side beam of the heddle frame, to which it may be fixed. The supporting element can be either unitary with the plastic material or connected to the frame via connecting elements.

Abstract: A draw hook having a bearing end, the outside circumference of which projects beyond the end of the baulk and serves simultaneously as stop against the recoil or repulsion knife and the stop rail. The drawing force for the movement of the heddle frame occurs from the draw hook directly through the bolt onto the baulk. The reaction and the holding force act directly onto the bearing end of the draw hook.

Abstract: In hand looms a plurality of moveable parts of the loom are interconnected by means of the different loom parts.An improved attachment of tying up strings wherein the tying up string consists of a crochetted string shaped as a continuous series of loops, which are used for effecting the interconnection of said loom parts either alone, in pairs, and/or with or without separate fitting members thereby eliminating manual tying work.

Abstract: A ribbon loom has a reed drive, a weft-needle drive, an operating needle drive and a shed-forming drive. A main drive shaft carries discs and/or cam discs to which the first-mentioned three drives are directly and articulately coupled. An auxiliary drive shaft extends transverse to the main drive shaft and is connected to the shed-forming drive; it is coupled to the main shaft via a worm transmission the transmission ratio of which can be varied by replacing the worm wheel with a differently dimensioned one.

Abstract: Generally, a weft guiding comb for a jet loom constructed in accordance with this invention comprises a root portion, an annular portion integrally connected to the upper end of the root portion and forming an aperture with a slit to allow a weft yarn passed through the aperture to come out of the latter, a fluid passage formed in each of said root and annular portions to allow a flow of fluid to flow therethrough, and a fluid outlet or outlets arranged around the periphery of the aperture for discharging the flow of fluid passed through the fluid passages. The weft guiding comb further comprises a relatively long and narrow fluid path or paths disposed between the fluid passage formed in the annular portion and the fluid outlet or outlets for orienting the flow of fluid, passed through said fluid passage in said annular portion, in a predetermined direction.

Abstract: A device for holding the weft yarn outside of a pair of takeoff rolls after there has been a filling break or upon starting up of the loom. The takeoff rolls in normal operation withdraw a measured length of yarn from a supply package and feed the yarn to a storage device such as a suction tube. The rapier on its filling stroke withdraws the measured length of yarn from the storage tube on each stroke of filling insertion. As the rapier approaches the end of the stroke, the takeoff rolls 4 and 5 separate so that the final portion of the yarn of each filling is taken directly from the supply package. After a filling break or upon starting up of the loom, in order to insure that the length of the first weft yarn is proper, a movable guide arm 14 holds the yarn outside of the takeoff rolls 4 and 5 and the yarn is manually withdrawn from the supply package. At the end of the first stroke of the rapier the rolls 4 and 5 are separated.

Abstract: Method and apparatus for carrying out the filling operation in a jet loom, wherein a main nozzle is provided for flying a weft through a guide passage formed on a sley at the time of each filling operation. When the supply of a compressed fluid into the main nozzle is stopped immediately after the completion of a filling operation, the compressed fluid present between a transfer valve connected to a fluid supply source and the main nozzle is positively discharged into the atmosphere simultaneously with the stopping of the supply of the compressed fluid, so as to promptly reduce the fluid pressure in the main nozzle, by utilizing the transfer valve designed for the present invention.

Abstract: A small table-top hand operated weaving apparatus on is disclosed upon which various patterned fabrics can be woven by extremely simplified operations thereof. In the disclosed apparatus, each heald member is mounted for movement along an inclined path with let-off and take-up rollers located on the same side relative to the path of the healds so that the warp yarns turn their direction at an angle, such as a right angle, at the healds. The heald members are automatically positioned selectively to either of the two end positions of their paths in accordance with a heald selection program by a manual reciprocating movement of a heald selection carriage movable transversely along the apparatus in order to form a desired shed with the warp yarns.

Abstract: Loss of tension in individual warp threads is detected in the lease zone by directing a flow of air against one side of the warp threads within the lease zone to displace any relatively untensioned thread toward the opposite side of said zone and detecting such displacement photoelectrically. Preferably, the photoelectric detector is insensitive to disturbances other than thread displacement.

Abstract: A selvage forming device is provided with cooperating thread distributing elements which perform relative vertical movements to each other over prescribed distances while utilizing shedding motion of harnesses for plain weave only in order to distribute at least one leno warp for one course of leno weave alternately onto different lateral sides of each ground warp controlled by a guide needle once in every pick by means of sliding contact of their slat edges with the leno warp, thereby forming stout leno selvages for woven cloths with simplified construction and movements of the related mechanical elements.

Abstract: Shed forming device for looms of the type having members (1) operated by a common rotating drive shaft (9) and linkages (2, 4, 6) controlled by the members (1) to move the heald frames. Between the drive shaft (9) and each of the members (1) there is interposed a clutch controlled by the fabric pattern model or paper by per se known, structure, by which clutch the position of the member (1) can be released from the movement of the shaft (9).

Abstract: An encapsulated shuttle grip for use in shuttles for holding bobbins in a properly aligned position during weaving. The grip includes a pair of opposed leaves which have opposed gripping jaws for receiving a butt end of a bobbin. Inner shank portions of the leaves are imbedded in a molded housing with the gripping jaws extending outwardly from the housing. The molded housing extends around the remote sides of the inner shank portions and in the space provided between the shank portions positively positioning the gripping jaws for receiving the butt end of the bobbin.

Abstract: 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.

Abstract: A double-lift open-shed Jacquard machine with two lifting bars which are movable in opposite directions to each other and pass each other, and with flat-bar lifters which can be controlled by main needles whose maximum moment of resistance lies parallel to the direction of movement of the main needles and which have two main projections associated with the movable knives, a holder-up projection associated with a fixed upper-shed knife, and at the lower end an engagement point for a harness cord. The two main projections, the holder-up projection, and the engagement point, for the harness cord lie on a straight line as seen crosswise to the direction of movement of the main needles, and the holder-up projection stands off from the flat bar lifter transversely to the direction of movement of the main needles.
