Abstract: A weft transfer device having special configuration of leading and drawing pincers for inserting the weft in a shuttleless loom. The device includes a leading pincer having a boxlike body shaped to offer the entrance at high speed of the wefts and smooth sliding of the warp threads and a rigid and semi-rigid grasping surfaces, the semi-rigid surface being pressed toward the rigid surface by two independent leaf springs engaging the lateral edge of the semi-rigid surface blade. The drawing pincer includes a lower fixed grasping member and an upper hook-shaped member pivoted to the lower member and forced into engagement therewith by a leaf spring.

Abstract: In a textile loom, the invention comprises a device for varying the speed and the tension of unreeling the warp threads from the warp beam. The device essentially includes a set of interchangeable spur gears connected to the warp beam which cooperate with a system of variable-race sheaves so that when a sheave has its race becoming narrower, the other sheave has its race widened and vice versa. Proper linkages are also provided to ensure that there is always a constant balance between the tension of the warp threads and the speed of rotation of the warp beam. Consequently, as the diameter of warp threads on the beam is decreased and the speed of the warp threads is concurrently decreased, the device imparts a pull increase to the warp threads so that the unreeling speed of the threads from the warp beam is automatically brought back to a preselected constant value.

Abstract: In the proposed apparatus for winding a weft thread onto spools of carriers, there is provided a disk rotatable in the horizontal plane on which are mounted constantly meshed satellite gears and winding members rotated by these satellite gears which engage, in a zone of winding of the weft thread, a stationary toothed sector arranged coaxially with the rotatable disk. In addition, provided in the apparatus are also a device for retaining the winding members in a preset position after the satellite gears disengage from the toothed sector and a device for gradual starting of the winding members and for stopping them in a predetermined position which precludes impacts and breakage of teeth at the engagement of the satellite gears with the toothed sector. This arrangement makes it possible to increase the speed of winding of the weft thread onto the spools of the carriers and to wind a required amount of the weft thread onto the spools of the carriers.

Abstract: A method of and a device for stopping the movement of a weft-carrier or shuttle when an obstruction is in the shed of a loom without damaging the loom or fabric being woven. The device includes a power operated shuttle drive mechanism adapted to engage the shuttle to move the shuttle through a shed, and a sensitive section adapted to be responsive to forces produced by an obstruction in the shed. When such forces exceed a predetermined value, the sensitive section actuates a transducer to stop the supply of power to shuttle drive mechanism and reduces to zero the forces being applied to the shuttle by its drive mechanism.

Abstract: In a loom for Turkish towelling, a device is disclosed for varying the beating-up position of the reed, said device essentially comprising a set of feelers mounted on the hinged loom reed and which are constantly in contact with a set of forked profiles mounted on the loom frame, the forked profiles being adjustable as to their positions by specially provided control members. The control members essentially consist of a set of eccentrics keyed onto a single shaft which is driven by a control cam. This arrangement reduces the parts having a reciprocal motion to a minimum and prevents bumps and consequent breakage occurences.

Abstract: The invention relates to apparatus for charging weft thread carriers in wave-type shedding looms. The apparatus comprises a thread guide including a rod having an opening made in one end thereof for the passage of a thread, the other end being pivotally connected with a drive and said rod is mounted in a support disposed intermediate the ends of the rod and arranged so that during a charging operation the ends of the rod are driven through circular motions. The apparatus reduces the thread charging time and also reduces the thread breakage rate, owing to less mechanical action upon the thread.

Abstract: In a shed-forming device for a loom which simultaneously weaves a number of fabric lengths and in which heald-moving cams are arranged along a helical path, the improvement of providing couples of matched levers which are not bound to each other, and wherein one lever is controlled by a cam and the other lever is controlled by a spring, so that said levers are kept in a contrasting or opposing relationship by the control mechanisms.

Abstract: A device for displacing the weft-carriers in a weaving loom which comprises an endless chain composed of discrete links, one of the links having a space in which a carriage with a carrier roller is arranged. The links are universally connected to one another so that they can be displaced on planes which are perpendicular to each other.

Abstract: In a multished weaving loom, the revolving comb is reliably supported by members in the form of a certain number of rollers or pads or combination roller-pads having a bladelike configuration, to be inserted in the interdisk gaps of the revolving comb so as to rest on the interdisk spreaders.

Abstract: The invention relates to a device for holding weft yarns in a shuttleless loom with continuous weft feed and more particularly for holding the cut change thread to be folded up into the shed to form a selvedge in a fabric manufactured on said loom.The device comprises a plate, adjustably mounted to the lower cutter of the cutting device of the loom, and a leaf spring pressing against said plate, whereby the weft yarn to be cut is gripped therebetween and kept into a taut state, while the weft yarn is being cut and then gripped by the gripping hook for the folding up into the shed. The device further comprises holding means in the form of a bar cooperating with said gripping elements, by which the weft yarns are held and arranged so that all of them are starting from the same position in the hooking zone, and are prevented from becoming entangled with the other weft yarns still attached to the edge of the fabric.

Abstract: Weft-cutting apparatus for a shuttleless loom of the type having a continuous weft supply and in which a selected weft thread coming from a fixed bobbin mounted at a point spaced from the fabric prepared on the loom remains attached to the edge of that fabric during the movement of a picking needle inside the shed and until after it has been beaten into the fabric, is constructed of an upper L-shaped lever and a lower L-shaped lever, fulcrumed at their midpoint on a common pin to provide a gap between them which is located in the path of the weft thread. Each lever supports a transverse cutting blade at one end and, at its other end, a sliding roller which rides on an associated control cam.

Abstract: Means are provided for entraining the free ends of weft threads extending from a formed fabric in movable suction hoses at each side of the loom. The hoses manipulate the weft thread ends into a position adjacent the sheds where hooked needles engage and fold the ends into the shed prior to beating. The weft threads on the side of the fabric which are attached to bobbins are folded into the sheds according to the pick repeat of the loom and the threads on the opposite side are folded into the next shed.

Abstract: A device is described which permits automatic, uniform, and precise shearing of cloth pieces, including those areas near the seams, and which thus minimizes the economic loss due to non-sheared areas of cloth. The device employs the logic processing of information continuously delivered by a detector which measures the thickness of the cloth at a point before it reaches the shearing cylinder. This information is processed in an electronic system so as to adjust properly the width of the shearing slit in synchronism with the movement of the cloth. By the technique described herein, spurious signals of thickness information caused by the presence of a seam are discarded and replaced by certain fictitious signals that will bring about the desired height of pile in the sheared cloth in the areas near the seams, while nevertheless permitting the seam to pass through the shearing slit.
