摘要： A feeding method and apparatus are provided for a extruder which is used for processing of rubber, plastic and cellulose etc. The feeding apparatus comprises an inlet, through which the materials enter the apparatus; a screw for transferring the materials from the inlet by rotating, which has helical flights and extends along the transfer direction of materials; a feeding roller at the inlet which has helical flights and extends along the transfer direction of materials. The helical flights of the screw and the helical flights of the roller are engaged untightly. The method comprises: providing a feeding roller at the inlet, the roller extending along the transfer direction of materials and having helical flights which mesh with the helical flights of the screw; making the helical flights of the roller engage the helical flights of the screw untightly; making the roller and the screw rotate in opposite directions when the extruder operates.
