This is a used bending and forming machine — specifically a complete coil line system — manufactured by Kohler and dating from 1990. Coil lines of this type, sometimes referred to as coil feed lines or straightener-feeder systems, are used in sheet metal processing to uncoil, straighten, and feed strip or sheet material into downstream forming, stamping, or cutting equipment. Kohler is a German manufacturer with a long-standing reputation in the field of coil handling and sheet metal feed technology, supplying equipment to pressing, stamping, and metal fabrication industries.
The line consists of three main components: a Kohler decoiler (type 3000.1) complete with a coil chair, a Kohler straightening machine (type KRM 50.260/2), and a hydraulically operated transfer bridge measuring 6,970 mm in length. Feed direction runs from right to left.
Overall, the line accepts sheet widths of up to 260 mm and sheet thicknesses of up to 6.5 mm, with a maximum coil weight of 3 tonnes throughout. Maximum feed velocity is 20 m/min.
The decoiler is a single-reel, traversable unit. It handles sheet widths to 260 mm and coil weights to 3 tonnes, with a mandrel expansion range spanning 460 mm to 530 mm, making it suitable for a practical range of coil bore sizes. A coil chair is included to support and load coils onto the mandrel, rated to the same 3-tonne capacity.
The leveller unit within the straightening machine is equipped with 21 leveller rolls, each 50 mm in diameter, providing a high degree of straightening correction across the material width. Maximum sheet thickness capacity is 6.5 mm, and the maximum material cross section is 1,500 mm² at a material tensile strength of 450 N/mm². Loop control is fitted, enabling the system to regulate material flow between the decoiler and straightener automatically. The machine is offered in used condition.
