Claims (11)

Form molten glass into filaments, store glass filaments as glass wool aggregates on a conveyor while spraying with a treatment agent that does not have binding properties but has water repellency and dust resistance, and evaporates the water content of the treatment agent supplied to the glass wool assembly. And a step of cutting the glass wool aggregate into small irregular shape materials with a garnet cutting machine and transferring the small materials to the packaging step, wherein the glass wool is blown to form an insulating material. The method of claim 1 wherein the mixture of liquid paraffin and silicone is used as a treatment agent in admixture with water and the precipitation of the liquid paraffin and silicone after heating and drying is adjusted to be in the range of 0.5-3.0% of the weight of the glass filaments. A housing; A garnet cutting roller; A roller for supplying the glass wool aggregate positioned to face the garnet cutting roller, and a plate for guiding the glass wool aggregate leading to the supply end of the conveyor for conveying the glass wool aggregate, and the guide plate in a nip between the two rollers. It has its feed end positioned and its position is installed on the housing in such a way that it can be adjusted in the machine direction to adjust the gap between its feed end and the peripheral surface of the feed roller, and the bearing of the garnet cutting roller has its position on the guide plate. It is installed on the housing in such a way that it can be adjusted in the machine direction to adjust the clearance from the feed end: a drive unit for the feed roller with adjustable rotational speed: a drive unit for a garnet cutting roller with also adjustable rotational speed For the production of glass wool to be blown to form a thermal insulator, etc. Three cutting machine for. 4. The machine according to claim 3, further comprising means for adjustably biasing the feed roller to adjust the compressive force acting on the glass wool aggregate between the feed roller and the upper surface of the guide plate. 4. The apparatus of claim 3, further comprising means for removing fibers adhering to the teeth of the garnet cutting roller, wherein the removing means is adapted to adjust the position of the removal means relative to the garnet cutting roller. Machine installed on the floor. 4. A machine according to claim 3, wherein the feed roller is made of hard rubber with flaws formed in its circumferential surface in its axial direction. 4. A machine according to claim 3, wherein the guide plate is made of metal with ceramic coating on the upper surface thereof. The machine according to claim 3, wherein the feed end of the guide plate has a thickness of 1 mm. 4. The machine according to claim 3, wherein the gap between the feed end of the guide plate and the outer circumferential surface of the feed roller is set within the range of 0.5-1.5 mm. 4. The machine according to claim 3, wherein the gap between the feed end of the guide plate and each of the teeth on the garnet cutting roller is set in the range of 1-3 mm. The ratio between the circumferential speeds of the feed roller and the garnet cutting roller is set in the range of 1: 4-1: 6 when the garnet rollers rotate at a circumferential speed in the range of 25-35 m / s. machine. ※ Note: The disclosure is based on the initial application.
