ラス糸の加工に対してはほとんど使用できない。The unbraced loom is used not only for making Italian gauze items, but also for making gold and glass dolls. As is customary in unprotected looms, the trap, which processes the glass thread, also requires that the glass thread unwound from the fixed storage roll be cut off at each weft threading at the insertion f1° of the binding machine. Pull out g at the opposite position like P1
It is necessary to cut the protruding long yarn ends in 11, or in some cases it is also necessary to cut multiple strips of fabric running parallel to each other.The conventional weft thread cutting equipment used in textiles is rarely used for processing glass threads. Can not.

を生ずる。This is especially true because the glass thread can tilt and deviate between the blades of the cutting shears p, as well as cause bends and thus the cutting or separation process to be carried out unreliably and inaccurately. Research is underway to develop a special weft thread cutting device for this purpose.A proposal in line with this objective is an improvement on the well-known weft thread cutting device of Isei Industries, in which the weft thread is placed on a flat plate used as an anvil. It becomes. The cutting of the thread is carried out by means of a cutting key which rests flatly and without play against the flat plate and crushes the exfoliation on the flat plate. To process the glass threads, a flat plate made of hard synthetic resin and a wear-resistant 91119 cutting edge are used. This method has a major drawback in that the lifespan of the cutting device is too short when processing glass threads, specifically when processing thin glass threads, so-called hair IP counterfeits. I had to replace it. This not only means a considerable amount of material wear, but also a large cost and working time due to ##4N processing and especially production stoppages. Furthermore, fragments of the plate can cause undesirable contamination.

記空隙の中に挿入できる＃ＩＦいフ。Book 9F! The aim of fi is to eliminate the above-mentioned drawbacks and to create a new weft thread cutter that can be used on glass threads with a very long service life. Various types of glass threads are used, such as simple threads of tl twisted, threaded with a neck attached to one strong thread, or many threads tied together in one string. The purpose is to cut the so-called lantern thread made of short capillary threads accurately.
In addition, in a weft thread cutting device for a bonding machine for glass thread processing, which consists of a shaft part and a movable shaft part, it is fixed. 1
#IF type, in which the movable shaft portion is comprised of a pair of wear-resistant plates separated from each other by a gap, and the movable shaft portion can be inserted into said gap.

に挿入されｆｃままである。The gap between the image plates is narrow enough to allow a straight safety razor blade as part of the movable shaft to be inserted therein. In this case, it is advantageous if the blades of the movable shaft part are guided in such a way that even when the shear is completely opened and the shaft is fully opened, part of the blade still remains inserted between the plates of the fixed shaft part. For this purpose, each plate has a projection at its bare end, with a portion of the movable shaft part always remaining fc inserted between said projections.

カミソリの刃が用い才することか挙げられる。According to the weft thread cutting device according to the present invention, the glass thread can be opened.
No cutting is achieved. The first advantage is that the glass thread does not bend at the cutting point and is cut at the exact length by the blade that enters the vacant house. applies equally to all conceivable types of glass threads and in all cases between 1N? In that case, whether or not the blade has a sharply honed edge is important.
Not g. Any contamination of the shaft portion by debris is prevented by the cutting device of the invention and does not settle into the voids. This cut I! The lifespan of one product is actually several times longer than what could be achieved conventionally, reaching more than 3 months. Additional advantages include the fact that blades can be replaced in less than 2 μm of time, and that a plain safety razor blade can be used instead of a special cutting blade.

A cutting blade consisting of a safety razor blade is supported at the top. The attachment of the cutting blade is carried out by means of fastenings that can be easily tightened and fixed like a bath.Therefore, the blade can be easily tightened. A contact roller is rotatably supported on the other arm b of the double-arm reperco, which drives the movable shaft part. This roller 1 is in contact with a roller t which is rotated in a relative rotational manner by a mechanism lIh7. Furthermore, a return coil is also placed on the arm t, and this

Pjil is removed by the upper part of l12, so it is removed at the 11th point (hidden tF).

In this fishing area, Fred 7 always sticks out to a certain extent between the plates LT/Qa and the inside of the dormitory. Like this lK4.
If you do this in the correct way, there will be no additional stress or damage to the thin frame. Even if the 7-ray dota comes out from the main hair part of the 9-gap that decides the t'l rib in the open fund, the blade is always guided by the 71"C. Even if the shear vibrates as it closes or moves to another four positions, the blade will never collide with the fixed part of the anvil and cause damage.
