Drop Feed

Durkopp Adler 281-140342 drop feed machinedrop feed machines

With an energy-saving and maintenance free direct sewing drive integrated in the machine head the new generation of high speed sewing machines 281 sets new standards. The Semi-Dry-Head with minimum lubrication of the needle bar and hook lubrication avoids stains on the work pieces and guarantees quiet running and durability.  Push button for manual back tacking, improves the handling in case of difficult sewing operations. The hand wheel for adjusting the sewing foot pressure allows a quick and reproducible adaptation to various materials. Apart from the thread nipper for a neat seam beginning, the thread trimmer and the automatic back tacking the basic equipment of the 281 also includes the motor control panel as well as sewing equipment for light-weight to medium weight material. The machine is also equipped with an electromagnetic sewing foot lift.

Needle Feed

Needle Feed 001The combination of bottom feed and needle feed of the lockstitch machine ensures absolutely displacement-free seams in thick and thin material. As in case of all machines, the sophisticated sewing kinematics provides an exemplary stitch pattern, even at maximum speed and with minimum thread tension and stress. Because of its durable, robust and service-friendly design the machine should be available as basic machine wherever trousers, jackets and coats are produced. With integrated sewing drive.

Puller Feed

Puller Feed 001Single needle lockstitch machine with bottom feed and top puller feed. Energy-saving, integrated sewing drive. Top puller feed with constant speed, working extremely behind the sewing foot. Usual clearance due to top puller feed to be swiveled upwards. Reproducible adjustment of the top puller feed via hand wheel. Neat seam beginning by means of thread nipper. Oil-free sewing point for work pieces without oil stains. Automatic sewing foot lift, thread trimming and back-tacking. Typical field of application. Long seams in all sectors of the apparel industry, especially for difficult-to-feed materials.
Puller Feed 002
The lockstitch machine is particularly powerful when processing difficult-to-sew materials like velvet. In order to achieve constant sewing results it is equipped with a “stroke level adjustment”. By means of this equipment the sewing foot can be moved in a position to hold the material safely without damaging the pile. Besides the needle feed, especially the top puller feed working extremely close to the needle ensures a displacement-free material feed and tension-free seams. With integrated sewing drive.

Top Feed

Top Feed 001Lockstitch machine with bottom feed, differential foot top feed for preassembly and assembly seams. Flat seams due to bottom feed and differential foot top feed, even in fine or difficult-to feed-material. Push-button for preprogrammed fullness. No feed marks in the material by means of patented light stroke system. Great variety of sewing equipment and optional attachments for optimum adaption to the sewing task. Excellent climbing properties when sewing over transversal seams. Easy and reproducible adjustment of top feed and stitch length via dials. Neat seam beginning by means of thread nipper.
Top Feed 002
Lockstitch machine with top feed for preassembly and assembly seams Maximum flexibility and quality for the ideal use e.g. in the production of men’s jackets and coats. Flat, displacement-free seams, even in difficult-to-feed materials. Integrated fullness control with sequence control for up to 8 steps. Digital fullness programming in steps of 0.1 mm. Great variety of sewing equipment and optional attachments for optimum adaption to the application. Neat seam beginning by means of thread nipper. No feed marks in the material by means of patented light.

Edge Trimmer

Edge trimmer sewing machineDoublelockstitch – machine with needle feed and edge trimmer. The machine is equipped with an edge trimmer to produce neatly cut seam edges. The trimming margin of the edge trimmer is between 3,5 and 8mm, depending on the sewing equipment. Also in fine fabrics the state-of-the -art sewing kinematics allows exemplary lockstitching. Even when sewing at maximum speed, with lowest thread tension and minimum thread strain every stitch is completed with precision and uniformity. Seam backtacking, thread trimmer and sewing foot lift are controlled electromagnetically so that the machine can flexibly be used without compressed air. The integrated DC direct drive enables a smooth and quiet running and guarantees a sensitive operation, especially when sewing “stitch in stitch”.

Edge Trimmer 002Lockstitch machine with top feet and separately driven edge trimmer. Energy-saving, integrated sewing drive. Separately driven edge trimmer with to trimming speeds for always neatly cut edges, even in corners and radi. Flat seams due to bottom feed and differential foot top feed, even in fine or difficult-to feed-material. Push-button for pre-programmed fullness. No feed marks in the material by means of patented light stroke system. Excellent climbing properties when sewing over transversal seams. Easy and reproducible adjustment of top feed and stitch length via dials. Neat seam beginning by means of thread nipper.

Edge Trimmer 003High Speed, 1-Needle, Needle Feed, Lock Stitch Sewing Machine with Vertical Edge Trimmer and Automatic Thread Trimmer. Since the knife operation device is mounted to the inside of arm, the work environment is simple. And with the use of the lever method that sufficiently considers the upper/lower knife clutch operation, it is easy to switch general sewing process into cutting sewing process.
