    • The invention relates to a single screw extruder comprising a barrier screw and a barrel in which the barrier screw is held in a manner that permits to rotate and comprising at least one feed zone longitudinal section and at least one melting zone longitudinal section (23). The extruder (10) is characterized in that the barrel (11), on the inner wall (50) thereof in the area of the melting zone longitudinal section (23), has at least one groove (52) which runs in a longitudinal direction. The invention also relates to a method for extruding plastic material using a single screw extruder (10) comprising a barrier screw (40) which is held inside a cylinder (11) in a manner that permits it to rotate, whereby the extruder (10) comprises a feed zone (21, 22) and a melting zone (23), and the barrier screw (40) has at least one solid matter channel (49) and a melting channel (48). The method is characterized in that solid plastic material (solid matter) is transported in the area of the melting zone (23) in a defined quantity out of the solid matter channel (49) and into the melt channel (48).
    • 本发明涉及一种单螺杆挤出机,其包括阻挡螺钉和筒体,其中阻挡螺钉以允许旋转并且包括至少一个进料区纵向段和至少一个熔融区纵向段(23)的方式被保持。 挤出机(10)的特征在于,在熔化区纵向部分(23)的区域中,其内壁(50)上的筒体(11)具有至少一个沿长度方向延伸的凹槽(52) 。 本发明还涉及一种使用单螺杆挤出机(10)挤出塑料的方法,所述单螺杆挤出机(10)包括以允许其旋转的方式保持在气缸(11)内的阻挡螺杆(40),由此挤出机(10) 包括进料区(21,22)和熔化区(23),并且阻挡螺杆(40)具有至少一个固体物质通道(49)和熔化通道(48)。 该方法的特征在于,将固体塑料(固体物质)在固体物质通道(49)中的限定量的熔融区(23)区域内输送到熔体通道(48)中。
