Slitting lines
Slitting
Coils produced in rolling mills are slit on slitting lines to narrow strands. They are the pre-product for punching and bending of final goods like razor blades, hose clips, flat cables and connectors for electronic wires, automotive stampings, rotor and stator lamination of electro motors, and many other goods.
NOBAG slitting lines fulfill the highest requirement regarding edge quality, precision, and productivity. Each slitting line is customized to the individual needs of the customer.

Slitter Types
Competencies
NOBS® slitter represent our worldwide reputation and they are the benchmark for the future. The first slitter was delivered in 1922. Since then, we combine engineering know how and experience with new innovative solutions, redefining technical limits with every delivery.

#coil_processing
Coil processing lines
In addition to the high-precision slitting lines, other machines and components complete the portfolio in coil processing to meet the needs of our customers in the best possible way.
Strip edge conditioning lines
Rounding refers to the reworking of the edges of slit strips (produced on slitting lines). The edges can be rounded, chamfered or according to other customer geometry requirements. The processing can be carried out by cutting (dry or wet) or without cutting.
Skiving lines
Skiving machines can be used to skive a geometry into a slit strip. The machine concept is similar to that of an edge processing machine. Skived strips are often used in the electrical industry.
Edge trimming lines / trimming shears
NOBAG trimming shears are used in particular for their precision and robustness. Separately driven cutter heads, absolute measurement of all movements and settings as well as an automatically adjustable gap are just some of the many special features.
Spooling lines / Traverse winders
Strips are wound onto spools (oscillating with many layers) so that the longest possible wire length per unit (spool) can be processed with narrow strips. This increases the line running time on downstream machines (e.g. automatic punching presses). Traverse winders can be used in slitting lines, edge processing lines, annealing lines and other coil processing lines
Slip-Tech friction winding systems
The major advantage of Slip-Tech recoiling systems is that a loop pit is no longer necessary. This leads to a significant reduction in construction costs and also increases the flexibility of the machine location. In many applications, it is also possible to dispense with a tension stand, which prevents damage to delicate material surfaces.
Rewinding systems
Umspulen von Material, damit die Coil Dimensionen auf die Anforderungen der Kunden angepasst werden können. Umspulanlagen können in Kombination mit Querteilen, Schweissen und/oder Verlegespuler ausgeführt werden.
Packaging systems / binding lines
We design packaging systems for slit strips according to the needs of our customers, from simple tilting and stacking units to complex systems with automatic strapping, weighing, labeling and automatic stacking to the desired storage location.

Slitting line SMM 125
The SMM 125 slitting line for transformer sheets is equipped with a high level of operating convenience. Components such as coil turners have been integrated to enable safe positioning and loading of the coils, regardless of the type of delivery.
Automatic infeed of the belt guarantees short downtimes. The ROTO waste strip cutter used fulfils all expectations in terms of performance and noise.
