Such material is generally made of textilefibers, but it may also be leather. It is used in the clothing industry andfor domestic and motor-vehicle upholstery.This special sewing machine can also be used to produce so-calledtechnical seams. In this case, however, the operator must assess thepossible dangers which may arise (with which DÜRKOPP ADLER AGwould be happy to assist), since such applications are on the onehand relatively unusual and, on the other, so varied that no single setof criteria can cover them all. The outcome of this assessment mayrequire appropriate safety measures to be taken.Generally only dry material may be sewn with this machine. Thematerial may be no thicker than 10 mm when compressed by thelowered sewing feet. The material may not contain any hard objects,since if it does the machine may not be operated without aneye-protection device. No such device is currently available.The seam is generally produced with textile-fibre sewing thread ofgauge up to 11/3 NeB (cotton), 11/3 Nm (synthetic) or 11/4 Nm(covering yarn).Before using any other thread the possible dangers arising must beassessed and appropriate safety measures taken if necessary.5
