Apparatus and method for determining a roller with a contact condition of a compressor is to be compacted ground when size representing

摘要

A device for determining a contact condition between a compressor roller and is to be compacted ground difficulty, representing the size (α) comprises, on at least one detection circumference region (18, 20, 22, 24) of a compressor rollers axis of rotation (d) rotatable compressor roller (12) at least one hand, a contact signal generating a contact sensor (1, 2, 3, 4), wherein the contact signal a contact the beginning (a) and a contact end (e) of a detection circumference region (18, 20, 22, 24) to be compacted with the substrate (14) to be indexed.
