Accessories

Right operating side SLMSS 1250

As an alternative, the machine may be controlled from the right operating side.

Continuously rubber-coated feed rollers (polished finish)

The continuously rubber-coated feed rollers improve the passage of sensitive material and prevent transportation marks on the material.

Additional paired blades

In addition to the standard set of 4 paired blades, the machine may be extended to a max. of 10 pairs of blades (depending on material).

Double guide roller to feed the material gently

A pair of guide rollers in front of the intake guides facilitate the infeed of material to the slitting machine. This prevents damage to the material (e.g., bending of the strip material in front of the machines intake area).

3 roller drag-straightening unit RIA3 (not driven)

The 3 reel drag-straightening unit can rotate by 180° and is suitable to straighten the coil twist of strip material being uncoiled from the bottom or the top. The target straightening position is easily adjusted by a single level pressure controller.

Reinforced 3 roller drag-straightening unit RIA3S (not driven)

The reinforced 3 reel drag-straightening unit can rotate by 180° and is suitable to straighten the coil twist of strip material being uncoiled from the bottom or the top. The target straightening position is easily adjusted by a single level pressure controller. The material is fed gently by double guide rollers that are attached in front of the unit.

6 roll straightening unit in a driven design (standalone machine)

In the 6 roller straightening unit facilitates 3 independently adjustable pairs of rollers for precise straightening of strip or sheet material. The straightening unit can be used in stand-alone mode or as an integrated part of a production line.

Protective foil unwinder SFB (not driven)

The protective film unwinder can unwind a self-adhesive protective film and apply to the top surface of the material.

Decoiler AH1250A1

A decoiler for metal coils with a max. weight of 1,000 kg and a max. coil width of 1,250 mm. The decoiler consists of a welded frame and a continuously adjustable mandrel on ball bearings with centre adjustment. The clamping range of the mandrel ranges from a min. of 280 mm to a max. of 530 mm inner coil diameter (optionally up to 650 mm). The manual braking assembly prevents metal coil overtravel. The decoiler is mobile because the decoiler is equipped with four swivelling castors. Extendable supports may be used to clamp the decoiler on site.

Decoiler AH1250K5

A decoiler for metal coils with a max. weight of 5,000 kg and a max. coil width of 1,250 mm. The decoiler consists of an exceptionally stable welded frame and a continuously adjustable mandrel on ball bearings with centre adjustment. The clamping range extends from a min. of 380 mm to a max. of 530 mm inner coil diameter. A standard braking assembly prevents metal coil overtravel.

Decoiler AH-PFL

A decoiler with pneumatic clamping for metal coils with a max. weight of 2,000 kg and a max. coil width of 800 mm. The decoiler consists of a solid, welded base frame, and a pneumatically actuated floating mandrel (6 bar working pressure). Because of the one-sided, floating support, the decoiler may be loaded from the front by a forklift or crane. The clamping range extends from a min. of 380 mm to a max. of 420 mm inner coil diameter. The support plates that are supplied with the unit extend the clamping range of the mandrel from a min. of 480 mm to a max. of 520 mm. The max. permissible outer diameter of the coil is 1,100 mm. A pneumatic brake prevents any overrun of the metal coils. Four pneumatic cylinders can extend the castors when the decoiler must be moved manually. When the castors are retracted, the decoiler is placed on four stands, i.e. it is secured on site against it rolling away.
