Abstract

A caterpillar track drawing method includes drawing a workpiece through a drawing die using a caterpillar track disposed behind the drawing die as seen in a drawing direction; and drawing a workpiece along a drawing line aligned parallel to the drawing direction while forming the workpiece by the drawing die. The caterpillar track includes circulating first and second drawing chains including chain links circulating parallel to a drawing plane. Each drawing chain is guided around first and second chain wheels having first and second axes aligned perpendicular to the drawing plane At least one measurable variable, inherent to the caterpillar track, of modules of the caterpillar track that resist or apply drawing force is recorded and optionally used for activation of a manipulated variable. In another aspect, a caterpillar track drawing machine includes the drawing die, the caterpillar track, and at least one measurable variable recorder.
