Expanded bunching machine portfolio

Niehoff's D1001 type double twist buncher ▲ ▲

due to the one-bow design of the machines. State-of-the-art three-phase drive technology and contactless machine data transfer reduce maintenance to a minimum. NBAT – Niehoff Bunching Automatic Traverse – automatically detects spool flanges and controls the traverse width of empty and full spools using optoelectronic sensors, without machine operator intervention. NBAT is offered as a standard on the D401 buncher and as an option on the remaining buncher sizes. All production parameters are set on the HMI touch screen, in the operator’s native language, and are clearly displayed together with all service messages. Maschinenfabrik Niehoff GmbH – Germany

Maschinenfabrik Niehoff has announced the addition of two new double twist buncher sizes to its buncher family product line: the D401 and the D1001. The product line now starts with type D401 designed for strands of 0.013 to 2.5mm² with continuous lay length and a maximum number of 9,000 twists per minute. The D401 enables the production of strands with 7 x 0.05mm construction as smallest strand variant, while the second type D1001 is the new powerful double twist-bunching machine. This machine completes the product line and is designed for strands of up to 50mm² with a lay length of 300mm maximum and a maximum rotational speed of 3,200 twists per minute. It is optimally suitable for large wire rope lay strands and battery cables of copper and aluminium. Both new bunching machines feature the technical advantages of the entire product line. Compared to conventional bunching machines, energy consumption and noise emission are reduced

Universal fault detector

automatically executes the measurement functions. The RS232 interface provides the connection to the host PC, which serves as the operating interface for the system and provides visualisation of all measurement values. A parallel interface and fieldbus interface are available for communication with the production equipment PLC.

1mm to 90mm. The UFD40 has features typically available in classic eddy current fault detection systems designed for automated production processes. These include adjustable frequencies, high and low pass filters as well as y-component and vector analysis. This makes the system suitable to monitor many different discontinuities with one type of hardware. UFD40 is of a modular design and offers several operating modes. The complete electronic circuitry for two independent measuring channels is housed in one IP65 module enclosure. Each channel

Roland Electronic GmbH has introduced a newly designed digital UFD40 system as a successor to its proven analogue UFD detector. The system has been designed to detect faults, butt welds and mechanical connections in wires, cables and small tubing made of metallic materials such as steel, stainless steel, copper, brass and aluminium. The UFD40 is based on the eddy current measurement principle; the material to be monitored passes through the orifice of an encircling coil sensor. Roland Electronic offers sensors suited for materials ranging in diameter from
