Drive and feeding units WITELS-ALBERT NA and NAB series

Haul-off and feeding units of NA 60, NA 100, NA 120, NA 160 and double-driven NAB configurations supply steady wire and profile conveyance. The mechanism guarantees stable pulling traction without slippage through synchronized heavy-duty drive roller shafts.

Pneumatic or mechanical roller clamping assemblies with finely tunable clamping pressure
Synchronized dual-axle roller transmission preventing material slip during acceleration
Standardized motor mounting flanges accommodating servo motors and planetary gearheads
Seamless integration into automated PLC lines supporting continuous and indexing feed

Preform heads and strand forming units series VB

Preforming heads of the VB series impart controlled helical deformation to individual wires and strands within stranding and cabling lines. The tooling prevents flare-out of wire ends during trimming and maintains uniform pitch across multi-wire wire rope layouts.

Multi-roller preform assemblies including VB 102, VB 122, and VB 142 strand geometries
Prompt adjustment of helical radius and twist pitch without dismantling forming heads
Hardened guide rolls with polished groove finishes preserving galvanized wire coatings

Strip, flat wire, and busbar straighteners series EB and BKV

Dedicated straighteners of EB and BKV series rectify longitudinal camber and transverse bow in flat strip, copper busbars, and profile stock. These units serve stamping operations, electrical sheet processing, and e-mobility busbar fabrication with high precision.

Wide cylindrical rollers ground to tight tolerances for flat strip and slit material
Symmetric gap regulation between upper and lower roller rows via calibrated dial screws
Processing conductive copper and aluminum busbars for e-mobility and switchgear builds
Prevention of edge wave defects and longitudinal twist ahead of precision press tools

Engineering principles of WITELS-ALBERT precision wire straighteners

Precision multi-roll straightening by WITELS-ALBERT eliminates internal residual stresses and curvature from continuous process materials. Wire stock progresses through offset rows of precision rollers arranged in mutually perpendicular planes, undergoing controlled elastic-plastic bending.

Upper roll positions are set via calibrated adjusting spindles with fine vernier dials. Proper adjustment of entrance rolls introduces necessary plastic strain to outermost material fibers, while trailing exit rolls establish final line straightness without surface work-hardening.

This mechanical methodology delivers continuous feed into high-speed spring coilers and welding units.

Selection of profile geometry and materials for WR and CA rolls

Operating longevity in roll-type straighteners depends directly on matching roller groove profiles to process wire diameter and metallurgical hardness. WITELS-ALBERT rollers are manufactured from hardened 100Cr6 bearing steel heat-treated to 60-62 HRC or premium tungsten carbide for high-wear runs.

Standard V-grooves feature opening angles of 90 degrees for stiff high-carbon wires and 100 to 110 degrees for copper and ductile non-ferrous alloys to prevent lateral pinch marks.

Precision internal bearings utilize labyrinth contact seals that exclude abrasive scale across production speeds reaching 70 meters per second.

Guiding roller boxes RK series for tracking and surface integrity

Roller boxes and guide assemblies of the RK, AR, and BZ series ensure stable spatial orientation for moving stock entering automated processing machines. Independent radial and axial roller positioning spindles permit accurate alignment with the pass line of rolling mills or drawing blocks.

Incorporating wear-resistant rollers with micro-polished finishes prevents vibration, axial misalignment, and longitudinal scoring on wire surfaces. Robust steel housings preserve rigid alignment under intense technological line tension.

Integration of WITELS-ALBERT NA series drive and haul-off modules

Motorized feeding units NA 60, NA 100, and NA 160 provide uniform pulling traction when advancing wire, tube, and structural shapes without slippage. Mechanical or pneumatic upper roller clamping allows technicians to dial in contact force based on raw material yield limits.

Synchronized rotation across upper and lower roller drive shafts eliminates wheel spin and prevents surface galling on drawn products. The modules connect easily to servo drives across automated stamping lines, high-speed cutoff machines, wire forming presses, and spooling winders.

Helical strand formation using VB series wire rope preformers

Preform heads of the VB series impart predetermined helical curvature to single wires and multi-wire strands immediately ahead of the stranding point in rope-making machinery.

Controlled three-dimensional pre-deformation neutralizes elastic torsional springing, ensuring the finished rope stays intact during cutoff operations without requiring end-welding.

Rotating forming rollers with ground guide tracks minimize frictional drag and protect galvanized and polymer coatings. Individual adjustment on forming shafts allows rapid adaptation of helical pitch to meet strict industry standards.

Maintenance schedule and replacement of fast-wearing straightening tooling

Consistent preventive maintenance on WITELS-ALBERT straightening equipment preserves final wire surface quality and minimizes downtime. Standard wear items include straightening and guide rolls, precision bearings, elastomeric oil seals, and guide slide blocks.

Checking radial runout and groove contour is carried out using optical templates or mechanical feeler gauges. Timely replenishment of high-temperature grease via exterior lubrication points prevents bearing overheating during round-the-clock industrial operations.
