To prevent a die from clogging at a melt coating of a regenerated resin from the scrap material of an automobile carpet containing fibers, improve the productivity of the regenerated resin and, in addition, prevent its physical properties from lowering due to the mixing of the fibers.

In the regenerating method of the scrap material of an automobile carpet through its cutting, crushing, separation and pelletization, its crushing is carried out with crushers, the particle sizes obtained with which range from larger meshes to smaller meshes. The smaller meshes are set to be 3-5 mm mesh. More preferably, the cutting is carried out by shearing. By the above- mentioned method, the quality and productivity of the obtained resin are improved. Further, by interlocking respective processes with one another, its productivity can be enhanced.
