Kolb offers different feeding devices from Ulmer to optimally feed the cable from the coil or from cable drums to the manufacturing process.

Coil unwinder system SAR

Abroller_SAR_01_q_1200The SAR coil unwinder system was developed as a cable dispenser that delivers material to the processing machines without back-pull. The possibility of a material damaging elongation of the insulation casing in conjunction with the touchless operation sag controller, through this system, is excluded.

The material coil is lifted via a pneumatically activated lift shell (option) and rolled by the operator to the two drive axes that close together. One of the axes can be moved through motor power (option) so that the coil slowly lowers into the unwinder. The support cones mounted on the side are moved into the coil bore and thus also permit the processing of slightly defective wooden or plastic coils.

Through the possibility of regulating the unwinding speed either via the touchless DHS1000D loop control or a cable accumulator of the KSP/LSP type series, the overall system can be adapted individually to the respective work process.
