<p>PURPOSE:To easily granulate the surface of fibrous sheets such as marginal material of carpet by roughly crushing fibrous sheets, melting the resin component at low melting point with friction heat on a crusher and further crushing the component, while cooling, into a granulated object containing fibers. CONSTITUTION:Fibrous sheets 1 having heat-melting resin constituent at high melting point heat deposited or adhered in the form of raising on a lining 11 mainly consisting of heat-melting resin constituent at low melting point are roughly crushed and then are fed into a crusher. Only the constituent at low melting point among other roughly crushed materials is softened and melted by friction heat generated by shearing action on the crusher. If the temperature of the treated material reached close to the melting point of fibrous material, the treated material is cooled. The crusher is further driven to crush to produce granulated object containing fibers.</p> |
