Precision stranding and laying of multi-core cables with uniform pitch control
The JP-LM Series Laying Machine is a heavy-duty cable stranding and laying unit designed for assembling multi-core power cables, control cables, and instrumentation cables. Individual insulated cores are simultaneously drawn from supply bobbins on a rotating cradle, brought together through a forming die, and twisted to a precise lay pitch before entering the outer sheathing process. Consistent lay pitch is critical for cable electrical performance — variation in twist angle directly affects capacitance balance, crosstalk, and bend performance.
Three models scale for different cable constructions and production volumes. The JP-LM 630 handles smaller multi-core constructions up to 12 cores on 630 mm supply bobbins — suited to control and instrumentation cable. The JP-LM 1000 extends to medium power cable constructions with a larger bobbin cradle and adjustable lay pitch. The JP-LM 1250 is the full production model for large power and control cables — up to 36 cores on 1250 mm bobbins, with independent tension control per bobbin and automatic pitch compensation for consistent stranding at variable line speeds.

Stranding 3, 4, and 5-core low-voltage power cables for building wiring and industrial distribution — precise pitch control ensures consistent cable geometry and electrical balance across all cores.
Precision laying of multi-core control cables for industrial automation and process control — uniform lay pitch maintains shielding effectiveness and reduces electrical interference between cores.
Pre-sheathing core assembly for SWA and AWA armoured cables — consistent core geometry before the armour application stage ensures uniform armouring and prevents core deformation under mechanical load.
Stranding flexible multi-core trailing cables for mining, port, and crane applications — soft strand formation and controlled lay ensures consistent bending performance and cable longevity in dynamic applications.
