Our loopers fit exactly in the sewing machine - one as the other Our loopers are made for exact fitting, all alike. This means simple exchange, without readjustment of the machine or resetting of the looper. We guarantee the closest manufacturing tolerances by using profile projectors with ten-fold enlargement. Tolerance of position looper point to looper shaft 0,05 mm = 0,002". MAIER-loopers made of high-alloy tool steel are fully hardened through. This means high stability at maximum speed and less wear especially in comparison with loopers which are only surface-hardened. MAIER-loopers are free from burrs at the critical points (with smooth thread contact surface) and highly polished.

Compact short-arm blind stitch sewing machine with skip stitch device and spring-loaded rib shaft (plunger). Compact and therefore vibration-free construction. Accurate stitching also at high speeds. Adequate working width for most of the blind hemming works. Retractable workplate. Small cylinder arm for sleeves, gloves etc. With skip stitch device 1:1 / 1:2 reversible (on request 1:3) With spring-loaded rib shaft (plunger) which is automatically depressed at changing cloth layers, e.g. cross seams, pockets etc. so that the needle pierces the upper cloth layer only. The spring pressure of the spring-loaded rib shaft (plunger) can be modified by means of 3 springs supplied with the machine.

Universal blind stitch sewing machine with skip stitch device and spring-loaded rib shaft (plunger) High performance blind stitch sewing machine. Modern shape with ample working width (17 cm). Retractable workplate. With skip stitch device 1:1 / 1:2 reversible (on request 1:3). Spring-loaded rib shaft (plunger); spring resistance adjustable infinitely variable to the kind of material. The presser foot shoe works like a tracer and is adjustable to the material thickness. When sewing over a cross seam, a pocket or any other thickness, it depresses the rib shaft (plunger) and the needle pierces the upper cloth layer only, i.e. no marks on the outside from thread pull.

No thread tension marks. Very flexible seam, invisible inside and out. Hem edge can be pressed down. The double blind stitch sewing machine with two independently adjustable, spring-loaded plungers. The material is fed through the machine in S-pleats. The needle penetrates once to the right and once to the left of the material break above it (zigzag stitch). The needle can be at any distance from the edge of the hem. It is very flexible and loose, and is invisible both inside and out. The loose seam prevents thread tension marks. On delicate materialsthe hem edge can be pressed down so that the seam does not make an impression visible on the outside. When sewing over cross-seams, the plungers automatically spring down, so that the needle only stitches the upper layer of fabric. Here, the two cloth retainers operate as sensors and can be adjusted to work with the most diverse fabrics. Result: no thread take-up marks on the outside over cross-seams.

Höhere Produktivität Die Verarbeitung von technischen Textilien stellt erhöhte Anforderungen an die Verschleißfestigkeit der eingesetzten Messer und Nähwerkzeuge, zum Beispiel Greifer. Durch den Einsatz von besonders geeigneten Stahlsorten und optimalen Fertigungsverfahren können wir die Standzeit deutlich verlängern. In der Praxis wurde schon eine bis zu 4-fache Standzeit erreicht. Renommierte Hersteller von Maschinen für den Automobil-, Flugzeugbau und anderen anspruchsvollen Branchen in Europa, Amerika und Asien vertrauen auf unser Know-how.

Better productivity The fabrication of technical textiles has to meet great demands on the capacity of resistance to wear of the knives and sewing tools applied, for example in regard to loopers. By using of especially suitable steel qualities and an optimal manufacturing process, we are in the position to prolongate the tool life in a significant manner. In practice, it happens that a tool life of up to the fourfold has been reached. Most renowned automobile manufacturers, aircraft constructors and other demanding branches in Europe, the United States and Asia are fully convinced of our know-how.

Double blind stitch sewing machine with 2 spring-loaded rib shafts (plungers) springing down when sewing over cross seams. For medium to thick material. Double blind stitch sewing machine with two spring-loaded rib shafts (plungers) independently adjustable from each other. S-shaped fabric feed to the machine. The needle enters the upper fold alternately from the right and left (zig-zag-stitch). The seam can be at any required distance from the edge of the hem. It is highly resilient loose and neither visible outside nor inside. The loose seam eliminates marks from thread tension. The edge of the hem can be underpressed so that it does not show outside. When sewing over cross seams the rib shafts (plungers) automatically spring down so that the needle pierces the upper cloth layer only. The two presser foot shoes act like a scanner and are adjustable to the different thicknesses of the fabrics. Result: over cross seams no thread pull marks on the outside. For medium to thick material
