1. A strand pelletizer for pelletizing a strand of material with
at least one cutting edge,
an opposite cutting edge, wherein
the opposite cutting edge is arranged on a base body and
the base body is linearly displaceable relative to a support body for adjusting the opposite cutting edge,
a feeding device for feeding a material strand into a cutting gap between the at least one cutting edge and the opposite cutting edge,
a first adjustment screw and a first pin which forms a first pivot axis and is displaceable by means of the first adjustment screw,
a second adjustment screw and a second pin which forms a second pivot axis and is displaceable by means of the second adjustment screw,
wherein the first adjustment screw is arranged on the support body and is connected to the first pin which is mounted on the base body so that the base body is pivotable relative to the support body about the second pivot axis, and
wherein the second adjustment screw is arranged on the support body and is connected to the second pin which is mounted on the base body so that the base body is pivotable relative to the support body about the first pivot axis.
