In this case however, the operator must assess the possibledangers which may arise (DÜRKOPP ADLER AG will be happy to offerits assistance), since such applications are relatively rare and at thesame time can be so varied that no single set of criteria can coverthem all. The outcome of this assessment may require appropriatesafety measures to be taken.Generally only dry material may be sewn with this sewing unit.
