摘要： A method to control the speed of the weft feed spool in weaving looms includes feeding at least two items of detected data related to weft delivery and supply, and loom operation, into a control mechanism, and using the data to calculate as a number of windings, the variation of the weft length reserve from the average minimum desired weft length reserve as determined by an average weft length reserve sensor and adjusting the speed of the feed spool in response to such calculations. A maximum weft length detector may be used as a control for the feed spool as well as a sensor for the time and number of unwindings of weft from the feed spool.

摘要： A device for supplying weft threads in airjet weaving machines includes at least one nozzle connected to a compressed air source, a buffer tank, a cutoff valve placed in a funnel between the compressed air source and the nozzle, and a controlled throttling device. The throttling device is mounted downstream from the buffer tank and in the immediate surroundings of the cutoff valve, and includes the funnel, a rotary throttling element, and a motor for rotating the throttling element. The funnel is divided into an inlet funnel and an outlet funnel connected to the inlet funnel. The rotary throttling element fits within the inlet funnel and rotates to selectively block an entry to the outlet funnel according to the degree of rotation of the throttling device.

摘要： A method for regulating the supply of weft thread on weaving machines includes the steps of winding the weft thread from a thread supply by means of a draw-off roller driven by a motor, supplying the thread to an accumulator, and controlling the draw-off roller motor by a pulse train generated on the basis of a set value and a second pulse train whose frequency is proportional to the main shaft of the weaving machine. By adjusting the set value, the speed of the draw-off roller can be adjusted to account for such factors as thread type, thickness extensibility and diameter, and also thread supply package diameter and variations in thread draw-off speed. A device for implementing the method of the invention includes, in a preferred embodiment, a cam, a set value setting unit, a shaft pulse generator for generating the second pulse train, a buffer, and a counter which adds the set value and the second pulse train to generate the first pulse train.

摘要： An auxiliary nozzle for an air jet loom is configured as straight tubule closed and tapered blade-like at its free end and moveable with the loom batten into and out of the formed sheds. At least one blow aperture near the closed end of the tubule is provided in the shape of a slot extending essentially transverse to the tubule axis. The slot has a width not exceeding 0.8 mm and lateral walls configured so that the least or critical cross-section is bounded at least on one side by an edge having a thickness not exceeding 0.2 mm. If one edge is provided, it is located on the lower side of the slot toward the air supply and away from the closed end of the tubule. Various aperture configurations are disclosed.

摘要： A drive system for weaving machines includes normally coupled main and auxiliary drive shafts for at least the batten and heddles of the weaving machine, respectively, with the shafts driven by main and auxiliary drive motors at different speeds through appropriate speed reducers and couplings. The shafts are coupled together at one point by an adjustable coupling that is controllable remotely so as to permit fine adjustment between the relative angular positions of the main and auxiliary drive shafts and therefore between the batten and heddle positions. This system has particular application during weaving machine start-up after a weaving interruption; e.g., when a thread break occurs. Various embodiments are described.
