摘要: A loom operating apparatus and method involving the use of an inverter device interposed between loom motor and power supply. The inverter device is controlled so as to make the motor torque greater than a rated value from immediately after start-up up to the completion thereof, and equal to the rated value thereafter. This eliminates contact wear and other disadvantages associated with the use of contact circuits, and allows the loom to be started up free of staggered weaves.

摘要: A shedding controlling apparatus for a loom wherein each of a plurality of heald frames is driven by a drive motor for the exclusive use therefor. During steady operation of the loom, when a crank angle is inputted to a position instructing section, the position instructing section produces an aimed amount of rotation, and a position controlling section controls the drive motor to rotate in accordance with the aimed amount of rotation to eliminate a deviation thereof from a crank shaft of the loom to establish a synchronized relationship between them. Then, when an operation instruction signal is generated during stopping of the loom, a movement instructing advice drives the drive motor by a predetermined amount of rotation by way of an OR gate and the position controlling section in accordance with a shedding pattern designated by way of a shedding instructing and shedding pattern instructing so that a leveling operation of the heald frame, a pick finding operation and a starting preparing operation may be performed automatically.

摘要: A seersucker loom is arranged such that puckering warp yarns are divided to form a shed during the weaving of a seersucker. The tension of the puckering warp yarns is maintained on a level below that of the tension of the ground warp yarns. The puckering warp yarns are slackened positively at least during a slackening period from a shed closing operation to a beating-up operating of every turn of the main shaft of the seersucker loom so that the tension of the puckering warp yarns are reduced to a value which below a predetermined tension of the yarns during a period other than during the slackening period. This enables the loom to slacken portions of the puckering warp yarns near the cloth fell sufficiently during the beating-up operation so that the puckering warp yarns are satisfactorily puckered.

摘要: A picking method and apparatus for a multicolor picking loom to provide changes in the number of rotations of the loom in order to pick a desired weft. In particular, a signal generation unit outputs a weft selection signal for each weft corresponding to a picking number, and a number-of-rotations selection signal also corresponding to a picking number. A plurality of number-of-rotations patterns are preset and each pattern corresponds to one of the number-of-rotations selection signals. In addition, a plurality of picking conditions are preset which correspond to the particular weft selection signal for the selected weft and to one of the number-of-rotations patterns. Of the plurality of picking conditions, the picking condition is selected which corresponds to the weft selection signal and the number-of-rotations selection signal, which allows the desired and selected weft to be picked.

摘要: In an electric shedding control apparatus, shedding patterns are stored in memories in such a manner that the shedding patterns are compressed and the time required to read the shedding patterns is shortened. An electric shedding apparatus is provided for driving each of a plurality of heddle frames independently and in synchronization with a rotation of a main shaft of a loom. Constituents of the shedding operations are set in advance, and the constituents are selected for each shedding step. Also, in order to drive the heddle frame, shedding amount instruction for the heddle frame is output in accordance with the rotation of the loom main shaft based on a shedding curve which includes the selected constituents.

摘要: A pile warp tension controller for controlling the pile warp yarn tension control mechanism of a pile fabric loom controls the position of the tension roller of the pile warp yarn tension control mechanism or the torque acting on a tension lever supporting the tension roller according to the operating state of the pile fabric loom so that the tension of the pile warp yarns is regulated at an optimum value. The control mode of the pile warp tension controller is changed over from a tension control mode to a speed control mode in forming loops of the pile warp yarns to ensure the satisfactory formation of loops having a predetermined loop length and to prevent defective loops.

摘要: A take-up control system for controlling a take-up motion included in a loom controls the take-up motion according to the diameter of a roll of cloth being woven on the loom so that a proper tension is exerted on the cloth. A take-up controller included in the take-up control system controls a torque-controllable motor for driving a cloth roller to take up the cloth in the roll on the basis of an electric signal representing the diameter of the roll according to a control program to exert a properly adjusted tension on the cloth. The take-up controller can also control an actuator for pressing a pressing member against the circumference of the roll according to weaving conditions, or weaving conditions and the diameter of the roll, to apply a properly adjusted pressure to the roll by the pressing member.
