Abstract

A processing unit for processing at least one filter tow strip to produce filters for rod-shaped smoking articles includes at least one tow guidance section along which the filter tow strip is moved in a direction of a longitudinal extension of the filter tow strip. The tow guidance section includes processing devices used for processing the filter tow strip. The processing devices are arranged in a sequence essentially one above the other, so that at least a segment of the tow guidance section that is located in a region of the processing devices is oriented at an angle to a horizontal line.
