DIMECO roll feeder range results from a combination of 5 mechanical models and 3 numerical control packages. They fulfil your needs for strips from 0,1mm to 10 mm thickness and up to 2000mm wide.
Cutting edge roll performances are reached thanks to an optimized inertia to reach up to 1000 rpm and 150m/mn. Rolls are hardened, chromed and sand blasted for a better grip.
The use of a comprehensive electronic package (sensors, motors, controls) provided by the same supplier selected among worldwide leading O.E.M. provides outstanding positioning accuracy and reliability (+/- 0,05mm).
You can select the HMI that most fits your needs: simple but efficient with ECODRIVE, sophisticated with SIMOSTAR370, which offers access to the entire operating and maintenance data on a 12” colour touch screen.
With PFS and ADA functions, feeding line machines speeds and accelerations are synchronized according to press rate, feeding angle and pitch. Material strains are therefore avoided, loop length may be reduced and machine lifetime is increased.
Built-in electronic cams and active safety device controls are programmed directly from the feeder terminal.

This system is made up of two roller conveyors. The rollers are covered with an elastic PVC sleeve. One conveyor receives the sheet while the other evacuates the finished material. The silent traction of the rollers is by means of a traction-belt.
The first conveyor has a pneumatic stop and is equipped with a lifting system which positions the sheet on its longest side. Gravity centres the sheet on its short side. The arms of the lifting system have built-in rollers which position the product to be withdrawn by a robot.

Roll feeder for high precision in feeding and high speed strokes.
A-WVS roll feeder series
have been developed to achieve high precision in feeding and high speed strokes. This garanted by large dimension of feeding rolls, which are pivoted in bearings without clearance. Drive force is supplied from AC-Motor, which provides the drive for upper and lower feeding rolls through pre tensioned gears mechanism
All gears are hardened and surface grinded.
The upper feeding roll can be lifted with support of pneumatic or hydraulic drive. This attachment can be used for to intermediate lifting as well.
The feeding length are freely adjustable. Different stepping modes can be choosen.
The roll feeder sytem is because of high feeding power and solid design prefered to be equipped with roll straighteners. Band cleaning and lubricate units can be added as well.
Wanzke first develeoped this roll feeder system AC-motors driven.
This roll feeder are used on new presses or as optimization of normal presses in use to increase the productivity.
Further applications: Cut to length lines , sheet production for transformer
Technical data:
Thickness of material: from 0,1 up to 20 mm.
Roll feeder sizes from 50 up to 1800 mm

RKB multi row bearings have low cross section, high load carrying capacity, stiffness and are used for metal rolling equipment in mills.
They are of separable design that considerably simplifies mounting, maintenance and inspection.
They can tolerate moderate to high shaft speeds. The rollers and outer races are carefully matched to ensure the best load distribution.
Inner rings (designation L) are interchangeable with other assemblies (designation R).
They have cylindrical bore and some sizes are also available with tapered bore.
The use of them in metal rolling mills exposes them to very heavy stresses.The rings and rollers can be manufactured with very high quality case hardened carburizing alloy steels. Deep case depth and special heat treatment ensure superior size stability, fracture toughness and reliability.
Where the bearings are mounted with a loose fit on the roll neck, RKB multi row cylindrical roller bearings have C2 internal radial clearance and are supplied with a helical groove in the bore and/or lubrication grooves in the side faces of the bearing rings for the efficient lubrication (e.g. suffix AC).
RKB produces the multi-row cylindrical roller bearings in several construction.
The various designs differ basically in the number of inner and outer rings, in the number of loose or integral flanges on the outer ring, in the cage type, and in the number of rollers in the cage pocket.
Furthermore, on order, RKB can produce the bearings sealed at both sides by radial rubbing seals or with wider inner ring.
They are produced with the normal precision grade for roll neck bearings, conform to class P6 for dimensional and running accuracy to ISO 492.

Four-row and six-row cylindrical roller bearings are used almost exclusively in the metal industry. Their friction is relatively low when compared with other roller bearings. As they are normally mounted with an interference fit on the roll neck, they are particularly suitable for rolling mill applications where the rolling speed is high.
Since very many rollers can be incorporated, the radial load carrying capacity is exceptionally high. Multi-row cylindrical roller bearings are unable to accommodate axial loads but they can be mounted together with deep groove or angular contact ball bearings or with tapered roller bearings to help accommodate any axial loads.

Spiracon is a high efficiency planetary roller screw which converts rotary motion to linear movement. Spiracon provides high dynamic load carrying capability up to 1200kN with high duty, life and positional accuracy ratings.
|
|
In roller screws, the load is transmitted from the nut to the shaft through the barrelled surfaces of all the engaged rollers. The diameter of the contact surface is substantially increased as is the number of points of contact.
Benefits
High load ratings (SR-SV)
Very high rotational speed (SR)
High acceleration and deceleration rates (SR)
Long life at high cycling rates (SR)
High reliability (SR-SV)
Resistance to hostile surroundings (SR)
Ability to survive shock loads (SR)
Small displacements with very good repeatability (SV)
Rotating the nut when speed becomes critical (SR)
Frequently removing the nut from the screw shaft (SR-most SV)
|
|
|
Nook Planetary Roller Screws are used in the most demanding and precise linear motion applications. With a greater number of contact points a roller screw provides stiffness and higher load ratings compared to a ball screw.
|
|
The screws with satellite rollers Rollvis are elements of machines of precision which are used to transform rotation movements into linear displacements and reciprocally.
The elements of bearing are threaded rollers laid out between the screw and the nut. The great number of contact points makes it possible the screw with satellite rollers to support very strong loads
The programme of sale of Elitec includes/understands screws with satellite rollers without recirculation of the rollers (constructions RV and BRV) and with recirculation of the rollers (construction RVR), that in various classes of precision.
In partnership with various types of nuts, Elitec delivers screws to satellite rollers for all the cases of application where high number of revolutions and/or strong loads are necessary.
