率を計算する着糊率計算手段とを設けた装置が提案され
ている（特開昭６１−６３６７号）。(Prior art) As a sizing rate measuring device for a warp sizing machine, it detects when the sizing liquid in the cavity box is consumed and the sizing liquid level reaches a predetermined level, and dispenses a predetermined amount of sizing liquid. a means for supplying a fixed amount of size liquid to the cavity box; a length measuring means for measuring the length of the warp threads running within the time period in which the predetermined amount of size liquid is consumed; An apparatus has been proposed that is equipped with a sizing rate calculation means for calculating the sizing rate from the warp length, preset size liquid concentration, warp yarn count, number of warp yarns, etc. -6367).
しかし、この装置における設定濃度はあくまでも机上の
計算であって、たて糸糊付の分野における糊煮機で糊液
を調製する際は、その都度濃度が変動するのが常であり
、糊液が供給されるキャビティボックスには蒸気が吹き
込まれ、通常９０℃以トに保たれているため−キセビテ
ノボ、、クス肉の糊液の濃液は吹き込まれる蒸気のドレ
ンにより濃度が低下し、湿り蒸気が少ないときは逆に水
分蒸発によって濃度が上昇することもある。However, the concentration set in this device is just a theoretical calculation, and when preparing size liquid with a size boiler in the field of warp sizing, the concentration usually fluctuates each time, and the size liquid supplied Steam is blown into the cavity box where it is stored, and the temperature is usually kept above 90°C. Conversely, the concentration may increase due to water evaporation.
また、前記のようにキャビティボックスには蒸気が吹き
込まれており、液面は上下しているので液面は正確に検
知できないという問題点もある。Further, as mentioned above, steam is blown into the cavity box, and the liquid level rises and falls, so there is a problem that the liquid level cannot be detected accurately.
したがって、実際の濃度と設定濃度がズしていたり、消
費量か正確に測定されないという欠点を有している。Therefore, there is a disadvantage that the actual concentration and the set concentration may deviate from each other, and the consumption amount may not be measured accurately.

The weight of the sheet-like material after drying was measured and calculated, but
Since the moisture content after drying fluctuates, conventional calculations using the formula below, which ignores the moisture content, sometimes produce abnormal values.
正確な着糊率を測定するには、糊付後の試料をサンプリ

抜処理をして、前記糊付シート状物の着糊率を補正する
必要があり、時間がかかるという欠点がある。In order to accurately measure the sizing rate, sample the sample after sizing, perform desizing treatment, and calculate from the weight before and after the process.Furthermore, unsizing blanks should also be subjected to desizing treatment. Then, it is necessary to correct the adhesive rate of the adhesive sheet, which has the disadvantage of being time consuming.
