Abstract
PURPOSE:To provide a high degree kneading type screw capable of obtaining a screw with high resin sending capacity and high melting capacity of a solid phase resin after break-up, by comprising specified instituting position of a dam and a depth of a groove. CONSTITUTION:In such a manner that a dam 3a between a first line flight 1 and a second line flight 2 is provided to just a midway position between dams 3b, 3b between the second line flight 2 and the first line flight 1, a dam instituting position is mutually set to a midway of a front and a rear dams in an adjacent groove due to multiple line flights. A depth of the groove provided between multiple line flights and the dam is adjusted so as to be made shallower toward a part nearer to the front and the rear dams along a lead of a screw S and made deepest at the midway part between dams. A resin in the multiple line grooves is moved and flowed always from one end to other end and mixing action of the resin is carried out.
