| (54) | Method and device for determining weight data for weaving operation and weight controller for weaving operation |
| (57) According to a method for determining weight data during a weaving operation, the
weight of a cloth roller (14) disposed in a loom (1) or the weight of a feeding beam
(3, 50, 64) is measured for every measurement interval to determine a weight change
of the cloth roller (14) or the feeding beam (3, 50, 64) in a corresponding measurement
interval. The length of cloth (8) woven during the measurement interval is determined.
Based on the determined weight change and the cloth-length data in the measurement
interval, a relationship between the weight and the length of the woven cloth (8)
or between the warp weight and the length of the woven cloth (8) is determined. A
weight-data determining device (100) for a weaving operation includes a weighing unit
(30) for detecting the weight of the cloth roller (14) for every measurement interval;
a cloth-length measuring unit (32) for detecting the length of cloth (8) woven during
a corresponding measurement interval; and a weight/length rate determining unit (33)
which determines the relationship between the weight and the length of the cloth (8)
based on a weight change of the cloth roller (14) in the measurement interval and
on the cloth-length data in the measurement interval. The weight change is determined
based on detected weight values of the weighing unit (30). |
