Abstract
A control technique is capable of adjusting a weight of a pile fabric by adjusting consumption of a pile warp at a proper range with a more simplified system. In a pile loom, a tolerance relative to a value associated with consumption of the pile warp is set, and the value associated with consumption of the pile warp is measured during a pile weaving period. If the value associated with consumption of the pile warp exceeds the tolerance, the weaving condition parameter associated with the weight of the pile is corrected in a direction to approach a target value of the weight of a pile fabric.
Claims22
A method of controlling a pile loom that is provided with a device for calculating a pile scale factor based on a ratio between consumption of a ground warp and consumption of a pile warp during pile weaving, said method comprising:
- setting a tolerance relative to the pile scale factor;
- correcting at least one weaving condition parameter associated with a weight of pile so as to change the pile scale factor in a direction toward returning the pile scale factor to a value within the tolerance when a calculated pile scale factor deviates from the tolerance;
- and
- not correcting the weaving condition parameter when the calculated pile scale factor is within the tolerance.
