のである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an instrument for measuring the air permeability (air permeability) of textiles, felts, etc. More specifically, it is an inexpensive portable air permeability meter that can easily and quickly measure industrial fabrics such as dryer canvases used in paper machines, felts, and filter cloths for gases and liquids at the site of use. It is related to.

紙から蒸発した多湿の空気が溜り、これがカンバ
スを通して新鮮な乾燥空気と入れ変つて乾燥を促
進する。 It is well known that the air permeability of industrial fabrics is an extremely important function depending on its purpose. For example, in the dryer canvas used in the drying section of a paper machine, weakly moist paper is dried by being pressed against many drying tubes, but the canvas is wrapped around the drying tubes in a staggered manner. Humid air that evaporates from the wet paper accumulates in the space, and this is exchanged with fresh dry air through the canvas, promoting drying.

て紙に含まれる異物、汚染物によつて汚され目づ
まりしてくる。従つて通気度が低下し部分的に不
均一になり乾燥度も影響してくる。 However, as this canvas is used for a long time, it becomes dirty and clogged with foreign matter and contaminants contained in the paper. Therefore, the air permeability decreases and becomes partially non-uniform, which also affects the degree of dryness.

These can be easily detected on site, and the fabric can be removed from the machine and thoroughly cleaned with chemicals, etc., and then reused.

ゆる感等によつて判定をしていた。(b) Prior Art Generally, the air permeability of fabrics is measured by the Frazier method specified by JIS. However, although this measuring device is a stationary type and has a fairly high degree of accuracy, it is very difficult to measure fabric that is still attached to the machine at a paper mill or the like. There are also some portable ones, 100c.c./cm 2 /
It cannot be applied to a wide range from min to 40,000 cc/cm 2 /min or more, and it is necessary to use a correction table, which is also heavy and cannot be easily operated. In addition, since the cost is quite high, it is not possible for each site to have their own, and whether the fabric is dirty or clogged has to be determined based on the so-called impressions of the site staff.

て測定した値に相当するよう刻印されている。 The suction port 2 serves as a measurement reference opening. A thin synthetic resin adjustment plate 6 called an adjuster is attached to this suction port. This adjustment plate has a curved ball-shaped oblique hole 8, and has a structure in which the opening area of the tube can be adjusted by rotating the adjustment plate about the mounting shaft. The adjustment plate is also engraved with a scale, and the movement of the adjustment plate can be read by means of a pointer 9 attached to the main body of the tube. The scale is engraved to correspond to a value measured using a known measuring object or gauge.

測定面積が定置式のものに比較して広いことは
測定誤差の入る要素を一つ減らすことが可能であ
る。 The fact that the measurement area is wider than that of a stationary type makes it possible to reduce the number of factors that introduce measurement errors by one.

る。 Also, this measuring instrument can be used at any angle, which is advantageous for field measurements. Although the suction tube is arranged in a T-shape in the embodiment, it can be freely arranged in a Y-shape, a 〓-shape, etc., and the structure and dimensions of each part are also made in accordance with the spirit of the present invention. All such items are included in the present invention.

この様な僅かな変動は意に介することはない。 FIG. 2 is a curve showing the characteristics of this measuring device. According to this, when the float is stabilized on the center line, it has a certain width, so the measurement with this device shows the air permeability of the object being measured by having a certain width compared to a stationary type pointing at a single point. However, such slight variations do not matter when measuring in the field.
