Title:
ジャカード式織機のヒ口の異常を検知するための方法
Document Type and Number:
Japanese Patent JP4878696
Kind Code:
B2
Abstract:
In a weaving loom of the Jacquard type comprising electrical actuators for displacing heddles controlling the position of the warp yarns, the following steps are carried out:a so-called "normal effort" is determined, exerted by at least one actuator on at least one harness cord in order to displace, between two positions of its normal stroke, at least one heddle connected to a normally taut warp yam;from this normal effort, at least one threshold value representative of a limit of a range of values of normal weaving effort is determined;while the loom is in operation, a so-called "operational effort" exerted by this actuator on the harness cord is determined;at least one value representative of this operational effort is compared with the threshold value, anda first, so-called "anomaly signal" is generated when the value representative of the operational effort is outside the afore-mentioned range.The device comprises a logic unit incorporating a comparator and associated with a memory and a display means.
