た。However, these conventional ones have the following problems. In addition, it is difficult to cut into 3 mm square by mass processing, and there is a problem that die is clogged because the adhered fiber is extruded as it is in a long state. In the case of resin, the fibers are difficult to cut and are long, so they remain as they are even after granulation, so they tend to be extruded and clog the die. Since the fibers enter the sheet as they are, the physical properties deteriorate when the amount of fibers is large and the fiber length is long. However, even if a compatibilizer is added, there is a problem that the effect is small and the cost becomes high. The present invention has a problem that productivity is low due to clogging of dies due to fibers and that quality is deteriorated due to mixing of fibers.

The end material of an automobile carpet used in the present invention is a tuft carpet having a nylon fiber pile as a surface fiber layer and a polyester spunbond as a base fabric, and a needle carpet made of polyester cotton and / or polypropylene cotton, and an ethylene / vinyl acetate resin on the back surface thereof. (EVA resin) with an inorganic filler, for example, calcium carbonate highly blended, coated at about 2 kg / m 2 and having excellent sound insulation, and a polyethylene resin on the back surface of the carpet of 0.3 to

ベルトコンベア上に落下する。First, the cutting process requires scraps. Although not particularly limited, a method of shearing with a blade cut in a mountain shape is preferable to pressure cutting with a sharp blade or fusion cutting with a blade heated. Since it is compressed and sheared from both sides, it can be gently cut with a small amount of force and the cutting section is not sharp, so there is an advantage that the fibers can be easily peeled from the resin in the subsequent cutting. In the cutting process, the pallet containing the scraps was hydraulically inverted into the receiver and the rear wall of the container was intermittently pushed forward by a certain size. It is sheared by a vertically-moving cutting blade having an upwardly moving tip and is intermittently dropped onto a belt conveyor which moves to the next crushing step.

室の中で行なうのが望ましい。The crushing is carried out in two steps from large to small with a crusher of large and small meshes. The small mesh is a 3-5 mm mesh. If it is less than 3 mm, there is some effect on the fiber removal surface, but the productivity is low, and if it is more than 5 mm, the fiber removal is reduced and the productivity and the quality are adversely affected. Grinding in two steps is done to prevent problems such as clogging of the mesh due to resin melting due to long residence time and large heat generation when crushing with a small mesh at a time so that crushing can be performed smoothly and with good productivity. Is. The number of small mesh pulverizers to be used later should be selected to be almost equal to that of the large mesh pulverizer, or the processing capacity of one machine should be selected.
Further, since the crushing process generates a lot of noise and heat, it is desirable to carry out the crushing process in a cooled adiabatic sound insulation room.

It can also be used for 0% melt coating. Further, when it is used as a chip with a virgin raw material, it is subjected to a pelletizing process. The pelletizing step may be a common extruder, but a granulator equipped with a heating kneader is preferred. The cut is hot cut, and the vibration transfer cooling device does not take up space and does not absorb water, which is advantageous in terms of cost.
