61 Apparatus and method for correcting irregularities in a series shed weaving machine US451797 1995-05-26 US5564473A 1996-10-15 Urs Schaich; Rolf Benz; Marcel Christe; Goran Dokic
An apparatus and method for correcting an irregularity during the insertion of a weft yarn into a weaving rotor of a series shed weaving machine involves drawing a length of weft yarn from a supply unit and delivering the weft yarn to the weaving machine in synchronicity with the weaving cycle. The length of weft yarn is inserted into a weft yarn conveyor apparatus and wound around a conveyor roller. A sensor is positioned between the supply unit and the conveyor apparatus to detect a weft yarn interruption, e.g., as a result of a weft yarn breakage or the yarn running out of spool. When the interruption is detected, the conveyor roller continues to deliver weft yarn stored in the storage apparatus until a complete weft yarn insertion into the weaving machine has taken place (i.e., weft yarn having a single loom width). The weft yarn is then cut at the insertion side of the weaving machine and the weaving machine is stopped. The weft yarn remaining in the weft preparation unit is then pulled back by the conveyor roller and discharged into a waste container.

63 Weft thread distribution device for a series shed loom US239100 1994-05-06 US5439037A 1995-08-08 Marcel Christe
A device for the distribution of weft yarns into weft ducts of a rotor of a series shed loom has a first part (7) rotating with the rotor (2) with transfer ducts (11) for the weft yarns and a second part (8) which is nonrotatable in relation to the rotor (2) and has connecting ducts (10) for the weft yarns. Between the first and second parts (7, 8) are three support units (30) which form a three-point support and keep the first and second parts (7, 8) spaced apart to define a gap (9) between them. This reduces friction between the first and second parts (7, 8) and improves the transfer and distribution of the weft threads.
64 Series shed loom US241955 1994-05-12 US5431194A 1995-07-11 Alois Steiner; Sandro Trecco
A series-shed loom for weaving a fabric from warp threads and weft threads. The loom has a rotor with reeds that comb through the warp threads and carries guide elements which define high points and low points. A multiplicity of elongated laying elements oriented parallel to the axis of rotation of the rotor guide the warp threads towards the rotor and insert them in the high and low points of the guide elements thereon. The laying elements are spaced from the rotor surface, they have a width in the direction of rotation, and warp threads which are adjacent in the fabric are guided over laying elements which are separated from each other by a pitch of at least twice the pitch between adjacent laying elements so that a point of intersection between the warp threads which are adjacent in the fabric is moved relatively further away from the laying elements and so that the point of intersection is further moved closer towards the rotor.
65 Series-shed loom with adjustable airjet delivery system for different loom widths US95329 1993-07-21 US5406985A 1995-04-18 Marcel Christe
A rotor for a series-shed loom is furnished, with relay system jets (3). These relay system jets (3) are located inside the rotor, and are supplied with compressed air by an air distribution system (10) via delivery stations. The delivery stations are distributed in the axial direction in order to produce a travelling field (22) relative to the loom rotor. At the same time, the delivery stations (6) are adjustably mounted in the direction of rotation (41) and are connected to an adjustment device (27, 33). The adjustment device permits the angle of rotation (8) between the delivery apertures (7) of various stations (6) to be adjusted at the broad side of the rotor (1). This also enables the maximum possible weft insertion angle .alpha. with the greatest possible weft insertion velocity to be used even with a reduced loom width (36).
66 Device for holding weft threads for series-shed looms US078480 1993-06-17 US5349990A 1994-09-27 Lorant Gacsay
A device or holding weft threads of a series-shed loom between a weft input side and a weft output side of a rotating rotor. The device includes one thread-holding device on the input side of the rotor, and one thread-holding device on the output side of the rotor, with at least one cutting device on the input side for severing inserted weft threads. Each weft thread holding device includes a device for clamping at least one weft thread at a first end on the input side, and at a second end on the output side. Each device for clamping includes a supporting surface extending substantially parallel to the central axis of rotation of the rotor and any device two endless conveyor belts lying over one another at least inside an angle of partial revolution of said rotor between said weft thread insertion angle to a weft thread discharge angle. The two conveyor belts are guided over guide rollers, so that an inlet slot for weft threads is produced in conjunction with the supporting surface. The conveyor belts move to capture the weft threads in the direction of rotation of the rotors. The distance of the supporting surface is increased within the angle of rotation from a first distance to a greater distance, whereby the weft thread is gripped between the clamping slots and moves away with respect to the center of rotation of the rotor to a release point with respect to the rotating rotor.

68 Weft thread preparation device US675237 1984-11-27 US4592393A 1986-06-03 Alois Steiner
The weft-preparation device for superposed shed type weaving machines comprises a weft measuring drums, a weft-severing device with a plurality of shears and a weft insertion device. Each shear comprises a blowing tube which conveys a weft yarn. The insertion or picking device has a guide duct for the weft which is open on one side and which is closable by a closure member. The severing device places before the guide duct entry whichever shear is guiding a weft for severance. The duct is then closed. When a weft has been fully picked in a picking comb, it is severed. The weft then remaining is conveyed by the blowing tube by way of the picking device into the next picking comb which has meanwhile entered. The severing device is then lowered one step at a time and the subsequent wefts are severed and picked.

71 Multiple longitudinal traversing shed weaving machine containing a weaving rotor US555592 1983-11-28 US4531553A 1985-07-30 Alois Steiner
At the weaving rotor there are alternatingly arranged with respect to the direction of rotation thereof first lamellae combs formed by beat-up lamellae for the weft threads and second lamellae combs formed by guide lamellae for the warp threads and including shed-retaining elements for the upper shed position of the wrap threads. The shed-retaining elements for the lower shed position are arranged within each pair of lamellae combs formed by a first lamellae comb and a second lamellae comb at the intersection point of the two groups of warp threads which assume the upper and the lower shed positions, respectively, and are formed by an element extending essentially parallel to the lamellae combs. In the lower shed the warp threads are thus always located in a common plane and the elements forming the shed-retaining elements for the lower shed position can be installed and disassembled without interference with the lamellae combs.
72 Apparatus for guiding a fluid medium driven weft thread in the shed of a weaving machine and use of the apparatus at a multiple longitudinal traversing shed weaving machine US575466 1984-01-30 US4492254A 1985-01-08 Alois Steiner
An apparatus for guiding a weft or filling thread in the shed of a weaving machine, the weft thread being driven by a flowing fluid medium, comprises two lamellae combs which can dip into and out of the warp threads. The lamellae or equivalent plate-like guide elements of the lamellae combs each possess a throughpass opening for guiding the weft thread and a thread exit or outlet opening. When the lamellae are in a position completely immersed in the shed they are interleaved or shoved into one another and form a guide channel for the weft threads, this guide channel being coherent or continuous in the weft insertion direction. Hence, the thread exit or outlet openings are sealed, so that the guide channel also is continuously closed in radial direction. The closed guide channel renders possible, on the one hand, a controlled flight of the weft thread, a reduced energy consumption and driving of the weft thread both by a blowing action and also by a suction action and, on the other hand, can be particularly advantageously employed at a multiple longitudinal traversing shed loom containing a weaving rotor.
73 Serial shed weaving machine with a weaving rotor US463022 1983-02-01 US4484603A 1984-11-27 Alois Steiner
The present invention relates to a serial shed weaving machine with a weaving rotor. Guide channels for weft threads transported by a flowing fluid are mounted on the weaving rotor. The guide channels are formed from a plurality of elongated, tube-like channel elements having a closable weft thread exit gap. The channel elements have complementary end configurations such that they can be moved together to form a closed guide channel. The channel elements are movable back and forth in the weft insertion direction. When the channels are moved in a first direction, the closed guide channel is opened and gaps are formed between the channel elements and each channel element is moved out of its associated part of the warp shed. When the channel elements are moved in a second direction, each channel element is moved back into its associated part of the warp shed and the guide channel is closed. The total excursion of each channel element in each direction is at least as great as the length of the element. Since the motion of the channel elements is exclusively back and forth in the weft insertion direction, the drive for such motion is relatively simple. Further, since the channel elements are each several centimeters long, the number of possible leak locations is sharply reduced over the prior art such that the weft threads may be inserted by suction air pressure.
74 Beat-up system US149479 1980-05-13 US4351367A 1982-09-28 Thomas F. McGinley
The present invention provides a method and apparatus for an improved beat-up system for beating up the weft threads into the fell of the fabric. The improved beat-up mechanism includes a plurality of spacer elements which are moved into and out of position between the warp threads for maintaining the spacing between the warp threads. The beat-up mechanism further includes a plurality of beat-up elements which are inserted into and out of position between the warp threads for beating up the weft threads onto the fell of the fabric. The beat-up elements also operate to maintain the spacing between the warp threads when the spacer elements are withdrawn from between the warp threads. In addition, the present invention discloses apparatus for increasing the spacing between adjacent groups of warp threads in the same plane so that weft-advancing arms or shed-retaining elements may be more easily inserted into the plane of the warp threads.
75 Shed retainer US58790 1979-07-19 US4285370A 1981-08-25 Thomas F. McGinley
